For example: I have to two roles in my application.
1.Administrator // Can perform all CRUD operations on data.
2.Customer // Can only Read the existing data.
In case of returning view to the User according to there role ?
Now I have a choice that create two separate views according to roles.
Let see some Code.
public ActionResult Index()
{
var customers = _dbContext.Customers.Include(c => c.Type).ToList();
if (User.IsInRole(userRole.IsAdministator))
{
return View("Admin_List_View", customers);
} else
{
return View("Customer_ReadOnlyList_View" , customers);
}
}
In the above code.I have two view.
1.Admin_List_View // This view contains all the Data along with Add,Delete,Update,Edit options.
2.Customer_ReadOnly_View // This view will only contains Readonly list.
So my question is that:
In case of simple view i have to follow this approach by writing a separate view for a target roles.
But as it Possible to have a single view and assign the specific section of that to specfic role ?
Note:
I am asking this question is that...In case of complex view that i don't have a choice to create another view from scratch for a particular role. So i am wondering that there is any way to play with the existing view.
For example:
I have to roles.
Admin & customer
and
i have one view.
How to manage that one view for these to roles?
Possible to have a single view and assign the specific section of that to specfic role ?
Yes. You can achieve this with Razor syntax which allows C# in your HTML. Prefix your C# statements with "#". See here.
In your View:
<button>Do Regular User Stuff</button>
#if(User.IsInRole("Admin") {
<button>Do Admin Stuff</button>
}
More Detailed Answer:
public ActionResult Index()
{
var customers = _dbContext.Customers.Include(c => c.Type).ToList();
if (User.IsInRole(userRole.IsAdministator))
{
return View("Admin_List_View", customers);
} else
{
return View("Customer_ReadOnlyList_View" , customers);
}
}
In the above example.
when have two roles and both roles have specfic view.
1.One way is:
to create two view for separate role
for the above example: i had created two views
1.Admin_List_View
2.Customer_ReadOnlyList
2.2nd ways is:
to create sample view and assign html contents based on a user role.
For example:
I have to roles:
again i will say that:
1.AdminList
2.CustomerList.
and now i have only one view:
index.cshtml
index.cshmtl
#model IEnumerable<Vidly.Models.Customer>
#{
ViewBag.Title = "Index";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<h2 id="heading">Customers</h2>
// This Button is accessible to only admin.
#Html.ActionLink("Add New Customer" , "Add" , "Customer" )
#if (Model.Count() == 0)
{
<p>No Customer is found.</p>
}
else
{
<table id="customers" class="table table-bordered table-hover">
<thead>
<tr>
<th>Full Name</th>
<th>Email Address</th>
<th>Physical Addrses</th>
<th>Type</th>
<th>Actions</th> // This Column will be only accessible to
admin role.
}
</tr>
</thead>
#foreach (var item in Model)
{
<tbody>
<tr>
<td>#item.FullName</td>
<td>#item.EmailAddress</td>
<td>#item.PhysicalAddress</td>
<td>#item.Type.TypeName</td>
// These Button will be only accessible to Admin
// This is the Edit Button.
<td><button data-customer-id="#item.Id" class="btn btn-link js-delete">Edit</button></td>
// This is the Delete Button.
<td><button data-customer-id="#item.Id" class="btn btn-link js-delete">Delete</button></td>
</tr>
</tbody>
}
</table>
}
#section Scripts{
<script type="text/javascript">
$(document).ready(function () {
$("#customers").DataTable();
$("#customers").on("click", ".js-delete", function () {
var button = $(this);
var result = confirm("Are you sure you want to delete this customer?");
function (result) {
if (result) {
$.ajax({
url: "/api/customers/" + button.attr("data-customer-id"),
method: "Delete",
success: function () {
button.parents("tr").remove();
},
error: function (xhr) {
alert("Something goes wrong." + " " + " Error Details " + xhr.status);
}
});
}
});
});
});
</script>
}
So This the entire view.
Now assigning specfic content to specfic Role:
#model IEnumerable<Vidly.Models.Customer>
#{
ViewBag.Title = "Index";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<h2 id="heading">Customers</h2>
#if(User.IsRole("Admin")) // Checking that if the LoggedIn User is Admin or Not? if The User is Admin Dispay this "Add New Customer Link" Otherwise don't display it.
{
// This Button is accessible to only admin.
#Html.ActionLink("Add New Customer" , "Add" , "Customer" )
}
#if (Model.Count() == 0)
{
<p>No Customer is found.</p>
}
else
{
<table id="customers" class="table table-bordered table-hover">
<thead>
<tr>
<th>Full Name</th>
<th>Email Address</th>
<th>Physical Addrses</th>
<th>Type</th>
#if(User.IsRole("Admin")) // Again Checking That the User is Admin or not? if the User admin Display the table Header otherwise don't display it.
{
<th>Actions</th> // This Column will be only accessible to admin role.
}
</tr>
</thead>
#foreach (var item in Model)
{
<tbody>
<tr>
<td>#item.FullName</td>
<td>#item.EmailAddress</td>
<td>#item.PhysicalAddress</td>
<td>#item.Type.TypeName</td>
#if(User.IsRole("Admin")) // Checking that the LoggedIn User is Admin or Not. If the User is Admin the Display these buttons otherwise don't Display it.
{
// These Button will be only accessible to Admin
// This is the Edit Button.
<td><button data-customer-id="#item.Id" class="btn btn-link
js-delete">Edit</button></td>
// This is the Delete Button.
<td><button data-customer-id="#item.Id" class="btn btn-link
js-delete">Delete</button></td>
}
</tr>
</tbody>
}
</table>
}

I am working on an ecommerce site where I am stuck on the cart management. Basically before login, products are kept in a session and I am trying to update the product quantity stored in the session using Ajax. I mean whenever I write in the 'Quantity To Change', the changed value should be reflected in the 'Quantity' column.
Note: I've shortened the post and figured out why it wasn't firing while debugging. Actually I was unable to get the id of the associated product. Now it passes the id. That's it. Now I've another issue - The TextBox are being created dynamically with a for loop. I used developer tools to figure out how the TextBoxes are generated dynamically and it is something like this:
For Product 1: cartDetails_0__Quantity
For Product 2: cartDetails_1__Quantity
I am wondering how to grab the quantity or values from the dynamically generated TextBoxes. If I put the generated id from HTML directly to Ajax, then it updates the quantity. Otherwise it doesn't. I've tried to use a loop in Ajax but I think, I am getting it wrong. Please see the View.
The view:
<table border="1" width="100%" cellpadding="4">
<thead>
<tr>
<th style="text-align:center;">Name</th>
<th style="text-align:center;">Price</th>
<th style="text-align:center;">Quantity</th>
<th style="text-align:center;">Quantity To Change</th>
</tr>
</thead>
<tbody>
#if (ViewBag.CartDetails != null)
{
for (int i = 0; i < cartDetails.Count(); i++)
{
<tr>
<td style="text-align: center; display:none;">#Html.DisplayFor(model => cartDetails[i].ProductId)</td>
<td id="ID" style="text-align: center;">#Html.DisplayFor(model => cartDetails[i].ProductName)</td>
<td style="text-align: center;">#Html.DisplayFor(model => cartDetails[i].Price)</td>
<td style="text-align: center;">#Html.DisplayFor(model => cartDetails[i].Quantity, new { #class = "quantityUpdate" })</td>
<td style="text-align: center;">#Html.TextBoxFor(model => cartDetails[i].Quantity, new { #class = "quantity", data_id = cartDetails[i].ProductId } )</td>
</tr>
}
}
</tbody>
</table>
<script src="~/Scripts/jquery-1.10.2.min.js"></script>
<script type="text/javascript">
var url = '#Url.Action("UpdateCart")';
$(".quantityUpdate").change(function () {
var id = $(this).data('id');
var i = 0;
$('.quantityUpdate').each(function (i, item) {
$.post(url, { id: id, Quantity: $("#cartDetails_"+i+"__Quantity").val() }, function (response) {
if (response) {
$("#TotalPrice").load(window.location + " #TotalPrice");
}
});
})
alert(id);
alert($("#cartDetails_"+i+"__Quantity").val());
});
Here is an image sample that I am trying:
$('.quantity').change(function(){
$('.quantityUpdate').val($('.quantity').val());
// put code here
});
Instant Change
$('.quantity').keyup(function(){
$('.quantityUpdate').val($('.quantity').val());
// put code here
});
If the idea is to call ajax when you change the value in .quality textbox then this is how you should do:
$('.quantity').change(function(){
//your ajax call
});
I have a similar question about jQuery button click handler code not being fired at all here.
In this case, it is being fired (when the jQuery is added to a static page (Index.cshtml)), but my REST method is still not being reached. The console message explaining why is:
The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.
Requested URL: /LandingPage/GetQuadrantData
Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.6.1055.0
This is the jQuery, which indeed gets fired when the button is clicked, but the REST call is not being made:
<script>
$(function () {
var btnGetData = document.getElementById('btnGetData');
btnGetData.addEventListener("click", function () {
alert("It works");
var unitval = 'ABUELOS';
var begdateval = '2016-08-07';
var enddateval = '2016-08-13';
$.ajax({
type: 'GET',
url: '#Url.Action("GetQuadrantData", "LandingPage")',
data: { unit: unitval, begdate: begdateval, enddate: enddateval },
contentType: 'application/json',
cache: false,
success: function (returneddata) {
},
error: function () {
alert('hey, boo-boo!');
}
});
});
});
</script>
The REST method is set up like so, in LandingPageController.cs:
[Route("{unit}/{begdate}/{enddate}")]
public HttpResponseMessage GetQuadrantData(string unit, string begdate, string enddate)
{
_unit = unit;
_beginDate = begdate;
_endDate = enddate;
. . .
I have a breakpoint on the "_unit = unit;" line, but it is not being reached; why not? What am I missing here?
The REST controller class under discussion begins like so:
[RoutePrefix("api")]
public class LandingPageController : ApiController
Note: If I use this in the jQuery ("Controller" appended):
url: '#Url.Action("GetQuadrantData", "LandingPageController")'
...both "GetQuadrantData" and "LandingPageController" are red in the IDE (Visual Studio) editor - the letters are red.
OTOH, if I use this (sans "Controller" appended):
url: '#Url.Action("GetQuadrantData", "LandingPage")'
(which has worked for me in the past, leaving the "Controller" off the Controller name), both "GetQuadrantData" and "LandingPage" are UNDERLINED in red, but the font remains the normal color.
UPDATE
Using Nico's link in his comment below, I changed the jQuery "url" line to this:
url: '#Url.Action("GetQuadrantData", "LandingPage", new { httproute = "" })',
...but it still didn't cause the Controller method to be reached.
UPDATE 2
Stepping through the javascript in the (Chrome) browser, I see that the "url" line has been dynamically changed from what it is at design time:
url: '#Url.Action("GetQuadrantData", "LandingPage", new { httproute = "" })',
...to:
url: '/api/LandingPage?action=GetQuadrantData',
I reckon what it should really have been resolved to is more like:
url: '/api/ABUELOS/2016-08-14/2016-08-20',
Am I right? Why isn't it being resolved like so?
If I manually enter that URL in the browser, so that the URL bar reads "http://localhost:52194/api/ABUELOS/2016-08-21/2016-08-27" it works - the method is reached and it "does its thing."
UPDATE 3
I tried this, too:
$(function () {
$("#btnGetData").click(function () {
document.body.style.cursor = 'wait';
$.ajax({
type: "GET",
url: '#Url.Action("GetQuadrantData", "LandingPage")',
success: function (retval) {
$("body").append($(retval));
document.body.style.cursor = 'pointer';
},
error: function () {
alert('error in btnGetData');
}
}); // end AJAX
}); // end click
}); // end ready function
...but only saw "error in btnGetData"
UPDATE 4
My most recent failure is this:
$("#btnGetData").click(function () {
document.body.style.cursor = 'wait';
var unitval = $('#unitName').val();
var begdateval = $('#datepickerFrom').val();
var enddateval = $('#datepickerTo').val();
$.ajax({
type: 'GET',
url: '#Url.Action("GetQuadrantData", "LandingPage")',
data: { unit: unitval, begdate: begdateval, enddate: enddateval },
cache: false,
success: function (returneddata) {
alert($(returneddata));
},
error: function () {
alert('error in ajax');
}
});
});
Again, I see only "error in ajax"
UPDATE 5

UPDATE 6
I know there's more to Arturo's answer than this, but so far just adding this:
config.Routes.MapHttpRoute(
name: "QuadrantData",
routeTemplate: "api/{unit}/{begdate}/{enddate}"
);
...has helped, as the breakpoint in my method is being reached. Unfortunately, it squawks "SyntaxError: Unexpected token < in JSON at position 0"
Personally not a big fan of using #Url.Action in javascript code; this is how I make ajax calls:
Create a hidden field in layout page to store the root url - <input type="hidden" id="hdnRoot" value="#Url.Content("~/")" />
Have a constants json file to keep my client side constants (constants.js) - assigns the hidden field value to serviceRoot variable:
(function () {
window.constants = {
serviceRoot: $("#hdnRoot").val() + "api/",
objectState: {
added: "Added",
modified: "Modified",
unchanged: "Unchanged",
deleted: "Deleted"
},
..other values...
};
})();
Will modify your ajax call as:
var root = window.constants.serviceRoot;
$.ajax({
type: 'GET',
url: root + 'LandingPage/GetQuadrantData/'+unitval+'/'+begdateval+'/'+enddateval,
// data: { unit: unitval, begdate: begdateval, enddate: enddateval },
contentType: 'application/json',
cache: false,
success: function (returneddata) {
},
error: function () {
alert('hey, boo-boo!');
}
});
[RoutePrefix("api")]
public class LandingPageController : ApiController {
[HttpGet]
[Route("GetQuadrantData/{unit}/{begdate}/{enddate}", Name="GetQuadrantDataFromLandingPage")]
public HttpResponseMessage GetQuadrantData(string unit, string begdate, string enddate)
Ok, this solution solves your problem but imply some changes in your code:
In the view, when you call Url.Action, you're trying to generate a webapi route from a mvc controller. You can see this question where I say how to do this.
Basically the idea is using Url.RouteUrl with an extra route value httproute = true.
Now, you need to change some parts in your code to be able to use this:
Firstly, you are using attributes to define your web api routes, therefore this routes will be added after the routes defined in your WebApiConfig class, and as I mencioned in the answer of the referenced question, Url.RouteUrl will return the first route that match the route values. So, you need to declare the route in WebApiConfig before the default route:
/* attributes removed */
public class LandingPageController : ApiController
{
public HttpResponseMessage GetQuadrantData(string unit, string begdate, string enddate)
{
...
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
config.MapHttpAttributeRoutes();
/* Route added before the default one */
config.Routes.MapHttpRoute(
name: "QuadrantData",
routeTemplate: "api/{unit}/{begdate}/{enddate}"
);
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
}
}
If you don't do this, the default route will be matched since {id} is optional and unit, begdate and enddate will be passed as query params.
Once fixed this issue, you have another problem, to be able to use Url.RouteUrl you need to know all the route values (unit, begdate, enddate), that are availables only when the script function is executed. But all razor code in your .cshtml is processed in the server when the html is generated for the client.
As you can see, when the javascript is executed you are not executing '#Url.RouteUrl...' or '#Url.Action...', at this time you are just handling a string with value returned when the razor expression was processed.
One thing you can do is pass "template" values to the Url.RouteUrl call, and replace it when the script is executed with the real values:
var url = '#Url.RouteUrl(new
{
unit = "(unit)",
begdate = "(begdate)",
enddate = "(enddate)",
httproute = true
})'
url = url.replace("(unit)", unitval)
.replace("(begdate)", begdateval)
.replace("(enddate)", enddateval)
$.ajax({
type: 'GET',
url: url,
contentType: 'application/json',
cache: false,
success: function (returneddata) {
},
error: function () {
alert('hey, boo-boo!');
}
});
After the replaces the value of the variable url will be like this /api/ABUELOS/2016-08-07/2016-08-13.
If you don't want to move the routes to WebApiConfig, you can set a name in RouteAttribute:
[RoutePrefix("api")]
public class LandingPageController : ApiController
{
[Route("{unit}/{begdate}/{enddate}", Name = "QuadrantData")]
public HttpResponseMessage GetQuadrantData(string unit, string begdate, string enddate)
{
...
And specify the route name in Url.RouteUrl call:
var url = '#Url.RouteUrl("QuadrantData", new
{
unit = "(unit)",
begdate = "(begdate)",
enddate = "(enddate)",
httproute = true
})'
This way is less intrusive in your code, but you need to know the name of the route you want to use.
Hope this helps.
You have a few issues with how you are generating the route and how you are trying to access it.
You Web API action is using attribute routing so by default there is no route name to match like in the convention-based routing.
Update the route attribute to include a name to find in the route table.
[RoutePrefix("api")]
public class LandingPageController : ApiController {
[HttpGet]
[Route("{unit}/{begdate}/{enddate}", Name="QuadrantData")]
public HttpResponseMessage GetQuadrantData(string unit, string begdate, string enddate) {
_unit = unit;
_beginDate = begdate;
_endDate = enddate;
//...other code
}
//...other code
}
Next even though you have the name you also need to include the template parameters in order to get a match from MVC and have it generate the url in the template you defined on the action.
To generate link to Web API, it would look like this
#Url.RouteUrl(routeName : "QuadrantData", routeValues : new { httpRoute = true , unit = "ABUELOS", begdate = "2016-08-07", enddate = "2016-08-13" })
or
#Url.HttpRouteUrl(routeName : "QuadrantData", routeValues : new { unit = "ABUELOS", begdate = "2016-08-07", enddate = "2016-08-13" })
which would add the httpRoute to the route values.

Now with your approach out of the way, I would suggest the following alternative approach.
KISS principle. Change Web API (REST) endpoint to POST and change its template.
[RoutePrefix("api")]
public class LandingPageController : ApiController {
//eg POST api/QuadrantData
[HttpPost]
[Route("QuadrantData", Name="GenerateQuadrantData")]
public HttpResponseMessage QuadrantData(string unit, string begdate, string enddate) {
_unit = unit;
_beginDate = begdate;
_endDate = enddate;
//...other code
}
//...other code
}
and send the data in the body of a JSON POST request
$(function () {
$("#btnGetData").click(function () {
document.body.style.cursor = 'wait';
var unitval = "ABUELOS"; //$('#unitName').val();
var begdateval = $('#datepickerFrom').val();
var enddateval = $('#datepickerTo').val();
var jsonBody = JSON.stringify({ unit: unitval, begdate: begdateval, enddate: enddateval });
$.ajax({
type: 'POST',
url: '#Url.HttpRouteUrl("GenerateQuadrantData", null)',
contentType: 'application/json',
dataType: 'json',
data: jsonBody,
cache: false,
success: function (returneddata) {
alert($(returneddata));
},
error: function () {
alert('error in ajax');
}
});
});
}); // end ready function
Regarding your point:
If I manually enter that URL in the browser, so that the URL bar reads
"http://localhost:52194/api/ABUELOS/2016-08-21/2016-08-27" it works -
the method is reached and it "does its thing."
Modifying your Ajax call like shown below should solve your problem and will send a GET request to the mapped url (Showing with button click event handler):
$("#btnGetData").click(function () {
var unitval = 'ABUELOS';
var begdateval = '2016-08-21';
var enddateval = '2016-08-27';
$.getJSON("api/" + unitval + "/" + begdateval + "/" + enddateval,
function (Data) {
// do what ever you want with the success response
})
.fail(
function (jqXHR, textStatus, err) {
// do what ever you want with the failed response
});
});
You're only giving your jQuery the controller and action names when it needs the full url to complete the request. Also, your end point has an 'api' prefix. You need your url property to be something like http://localhost:{port}/api/{controller}/{action} if your server is running locally.
I am working on asp.net MVC 4 application. I have created a list using foreach loop and declared a variable to show record number. Each row has a delete icon, which when clicked, deletes that record and hides that row. this works fine except one issue. When user deletes first record or any record in middle of list, I want the record number of all the rows to be updated accordinlgy.
Here is razor view code:
#{
int i = 1;
foreach (var item in cartItem.CartItemsByStore)
{
<tr id="cartrow-#item.CartItemID">
<td class="transaction">#i</td>
<td class="item-details">
<img src="/images/tmp/order-product.jpg" width="63" height="63">
<div class="desc">
<span>
<p>#item.ItemName</p>
</span>
</div>
</td>
<td class="date-time">15 Jun 2014</td>
<td class="action">
X
</td>
</tr>
<tr class="sp" id="sp-#item.CartItemID">
<td colspan="20"></td>
</tr>
i++;
}
}
and here is deletion code:
$(function () {
// Document.ready -> link up remove event handler
$(".removeCartItem").click(function () {
if (confirm("Click OK if you want to delete this record; otherwise, click 'Cancel'")) {
// Get the id from the link
var recordToDelete = $(this).attr("data-id");
if (recordToDelete != '') {
// Perform the ajax post
$.post("/Cart/DeleteCartItem", { "id": recordToDelete },
function (data) {
// Successful requests get here
$('#cartrow-' + recordToDelete).fadeOut('hide');
$('#sp-' + recordToDelete).fadeOut('hide');
$('#spCartCount').text(data);
$('#row-' + recordToDelete).fadeOut('hide');
});
}
}
});
});
Try this
Partial view : "Store.csthml"
#model IEnumerable<CartItemsByStore>
#{
int i = 1;
foreach (var item in Model)
{
<tr id="cartrow-#item.CartItemID">
<td class="transaction">#i</td>
<td class="item-details">
<img src="/images/tmp/order-product.jpg" width="63" height="63">
<div class="desc">
<span>
<p>#item.ItemName</p>
</span>
</div>
</td>
<td class="date-time">15 Jun 2014</td>
<td class="action">
X
</td>
</tr>
<tr class="sp" id="sp-#item.CartItemID">
<td colspan="20"></td>
</tr>
i++;
}
}
CartController:
public ActionResult ReturnView()
{
//populate model
IEnumerable<CartItemsByStore>model =db.GetItemsByStore();
return PartialView("Store",model)
}
public ActionResult DeleteCartItem(int id)
{
//delete
return RedirectToAction("ReturnView");
}
Main View:
<div id="divStore">
#Html.Partial("Store",cartItem.CartItemsByStore)
</div>
$(".removeCartItem").click(function () {
if (confirm("Click OK if you want to delete this record; otherwise, click 'Cancel'")) {
// Get the id from the link
var recordToDelete = $(this).attr("data-id");
if (recordToDelete != '') {
// Perform the ajax post
$.post("/Cart/DeleteCartItem", { "id": recordToDelete },
function (data) {
// Successful requests get here
$("#divStore").html(data);
});
}
}
});
