I want to insert data into SQL Server database when I click "Insert" button in excel.
The data is in Cells A2 and B2 and here is the code behind the "Insert" button in excel:
Dim HttpReq As New WinHttp.WinHttpRequest
HttpReq.Open "POST", "http://localhost:11121/Student/Insert/", False
HttpReq.Send "jsmith112"
Here is my code for the Controller action in VS:
[HttpPost]
public ActionResult Insert(string id)
{
try
{
student.AddToStudents(id);
student.SaveChanges();
return RedirectToAction("Index");
}
catch
{
return View();
}
}
This doesn't seem to be working, could anyone guide me into finishing this?
Thanks in advance
Just change the POST to
"http://localhost:11121/Student/Insert/" + id
and then map the route
routes.MapRoute(
"InsertStudent",
"Student/Insert/{id}",
new { controller = "Student", action = "Insert", id = "" }
);
and then in your controller you can check if id is empty, if not then make a new user
also, sometimes I do things like this
routes.MapRoute(
"Resource",
"{resource}/{operation}/{id}",
new { controller = "Resource", action = "Index", resource = "", operation = "" id = "" }
);
and then you could parse out what the things are..
as a side note and if you were making more end points for your service, you might consider using GET, POST, PUT, DELETE instead of actually having "Insert" in the URI. REST.
I don't think your controller action would see the data in this case. It has no way of knowing that the 'jsmith112' you sent should correspond to the string id parameter. Inside of your controller action, use the Request.InputStream object to grab the posted data and send that into the database.
A better way to do this would be to either send it through as url-encoded form data (so the post body would be 'id=jsmith112'), or to change the request to a GET (or a PUT, if you want to be properly RESTful) and hit this URL:
http://localhost:11121/Student/Insert/jsmith112
In that case it should be picked up by the string id parameter.
Also, put a breakpoint inside the controller action to be sure you're actually hitting it, then use the debugger to verify your web service has the data it needs.

I'm trying to hide the data from begin watched in the url, For example here is my route :
routes.MapRoute(
"Viewer",
"viewer/{id}",
new { controller = "Viewer", action = "Index" }
);
and here is the controller method:
public ActionResult Index(int id)
{}
as you see when i call the method it's gonna route and show the url like this :
www.domain.com/viewer/1234
I want to remove the Id from begin watched and i want keep the method running as expected like this
www.domain.com/viewer
So how i can do that ?
As you, Since you want to pass data with GET request, you have to send id or everything else that you can search and find that data. I suggest you hash URL. To hashing URL:
url hash
I want to change:
www.testurl.com/sports/blog/1
Where sports is my area, blog is my action and 1 is an ID of a blog post, to:
www.testurl.com/sports/blog/test-title-of-blog
Where blog is still my action but the id is not shown, but instead the title/permalink of the blog is.
Here is my AreaRegistration for this action:
context.MapRoute(
"sports",
"sports/{action}/{content}",
new { area = "Sports", controller = "Sports", action = "", content = "" });
Here is my action at the moment:
[HttpGet]
public ActionResult Blog(string content)
{
int contentId;
if (Int32.TryParse(content, out contentId))
{
model = service.GetBlogById(contentId);
}
else
{
model = service.GetBlogByTitle(content);
}
//Change URL to be: www.testurl.com/sports/blog/ + model.SEOFriendlyTitle
return View(model);
}
Users are able to search via the ID of the blog, but also by the title of it, but I only want the title to appear in the url bar, never the id.
I cannot do this via Redirect rules due to the continuing maintenance that would cause.
Is the controller the right place to do this? -Remember I may not have my title until after I retrieve it from the database using the ID
How would I go about changing the URL to display the title vs. the ID?
I think what you should do is return a RedirectResult to the new Url if the ID is numeric and is a valid contentId :
int contentId;
if (Int32.TryParse(content, out contentId))
{
model = service.GetBlogById(contentId);
if(model != null)
{
return RedirectResult(/*url using the title*/);
}
}
else
{
model = service.GetBlogByTitle(content);
}
//Change URL to be: www.testurl.com/sports/blog/ + model.SEOFriendlyTitle
return View(model);
Of course, that will cause another round trip to the server but I can see a way to change the browser URL without a page redirect. You should also make sure that all published urls on your site are using the title instead of Id.
I hope it will help.
I suggest giving this a quick read.

If you are really can't have the ID in Url and don't want to do redirects then I think storing Url as Slugs in the database is the only other option.
*Some points if you are going to do this.*
Add a Unique Constraint to the column at the Database Level to avoid duplicates.
Create a Database Index on this column to speed up you reads.
So with this Url
www.testurl.com/sports/blog/test-title-of-blog
This is your unique slug that you will query the database for instead of an ID
test-title-of-blog
I am beginner for .net MVC. I guess my problem is related to route setting.
What I want to do is :I get data from database, in controller transfer data to json format and pass to view, use javascript decode json data and show on the html.
When I write methods under TechnologyController, type localhost:portnumber/Technology/Index, no decoded json data in html format, but if I type localhost:portnumber/Technology/GetJson
It show me a page with pure json data (which means if I call GetJson() method separately, it works)
I write the same code in HomeController, it runs correct, all the route setting is default:
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
//This is my controller
public class TechnologyController : Controller
{
public ActionResult Index()
{
return View();
}
public JsonResult GetJson()
{
Technology myTech = new Technology(); //get data from database (Tested correct)
return Json(myTech.select(), JsonRequestBehavior.AllowGet);
}
}
//This is Javascript:
<script type="text/javascript">
$(document).ready(function() {
$.getJSON("Technology/GetJson/", null, function(data) {
sss.innerHTML+=data["title"];// this part is correct (I already tested,please ignore), the purpose is to parse json data to html.
.......
}
)};
)};
I understand if I call "localhost:portnumber/Technology/Index", it only execute index method, that is why GetJson method is not called, but what url should I call in order to call index() as well as GetJson.
something like:
$.getJSON("#Url.Action("GetJson","Technology"), null, function(data) {
edit 2-
Without Razor it would look like this:
$.getJSON("<%= Url.Action("GetJson","Technology") %>, null, function(data) {
Edit-
Wait you want to call Index AND GetJson? That should already be happening, just load the /index page which calls index controller action, then in the rendered script from there your invoking the GJson action. Why would you think you need to call Index again?
I imagine your method isnt getting hit because the url is incorrect. Grab fiddler*, and take a look at the acutal http traffic and see if it is 404'ing on the request.
*(once fiddler is running change your url to http://localhost:port/..... to http://localhost.:port/.....)
I guess you could modify the "index" method inorder to get the data from "GetJSon" method something like below.
public ActionResult Index()
{
return View("GetJson");
}
Hope this helps!!
I have a requirement to add specific functionality to an asp.net mvc2 web site to provide addtional SEO capability, as follows:
The incoming URL is plain text, perhaps a containing a sentence as follows
"http://somesite.com/welcome-to-our-web-site" or
"http://somesite.com/cool things/check-out-this-awesome-video"
In the MVC pipeline, I would like to take this URL, strip off the website name, look up the remaining portion in a database table and call an appropriate controller/view based on the content of the data in the table. All controllers will simply take a single parameter bieng the unique id from the lookup table. A different controller may be used depnding on different urls, but this must be derieved from the database.
If the url cannot be resolved a 404 error needs to be provided, if the url is found but obsolete then a 302 redirect needs to be provided.
Where the url is resolved it must be retained in the browser address bar.
I have had a look at the routing model, and custom routing and can't quite work out how to do it using these, as the controller would not be predefined, based on a simple route. I am also unsure of what to do to provide 404, 302 back to the headers also. Perhpas I need a custom httpmodule or similar but going there went beyond my understanding.
This must be possible somehow... we did it years ago in Classic ASP. Can anyone help with some details on how to achieve this?
Well, the simplest way would be to have an id somewhere in the url (usually the first option)
routes.MapRoute(
"SEORoute", // Route name
"{id}/{*seostuff}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional, seostuff = UrlParameter.Optional } // Parameter defaults
);
In your controller you'd have something like
public class HomeController {
public ActionResult Index(int id) {
//check database for id
if(id_exists) {
return new RedirectResult("whereever you want to redirect", true);
} else {
return new HttpNotFoundResult();
}
}
}
If you don't want to use the id method you could do something else like...
routes.MapRoute(
"SEORoute", // Route name
"{category}/{page_name}", // URL with parameters
new { controller = "Home", action = "Index", category = UrlParameter.Optional, pagename = UrlParameter.Optional } // Parameter defaults
);
public ActionResult Index(string category, string page_name) {
//same as before but instead of looking for id look for pagename
}
The problem with the latter is that you would need to account for all types of routes and it can get really difficult if you have a lot of parameters that match various types.
This should get you in the right direction. If you neeed some clarification let me know and I'll see if I can write a specific route to help you

You could probably do what you're looking for like
public ActionResult Index() {
//Create and instance of the new controlle ryou want to handle this request
SomeController controller = new SomeController();
controller.ControllerContext = this.ControllerContext;
return controller.YourControllerAction();
}
but I don't know any of the side effects by doing that...so it's probably not a good idea - but it seems to work.
I'm having some trouble with ASP.NET MVC Beta, and the idea of making routes, controller actions, parameters on those controller actions and Html.ActionLinks all work together. I have an application that I'm working on where I have a model object called a Plot, and a corresponding PlotController. When a user creates a new Plot object, a URL friendly name gets generated (i.e.). I would then like to generate a "List" of the Plots that belong to the user, each of which would be a link that would navigate the user to a view of the details of that Plot. I want the URL for that link to look something like this: http://myapp.com/plot/my-plot-name. I've attempted to make that happen with the code below, but it doesn't seem to be working, and I can't seem to find any good samples that show how to make all of this work together.
My Route definition:
routes.MapRoute( "PlotByName", "plot/{name}", new { controller = "Plot", action = "ViewDetails" } );
My ControllerAction:
[Authorize]
public ActionResult ViewDetails( string plotName )
{
ViewData["SelectedPlot"] = from p in CurrentUser.Plots where p.UrlFriendlyName == plotName select p;
return View();
}
As for the ActionLink, I'm not really sure what that would look like to generate the appropriate URL.
Any assistance would be greatly appreciated.
The answer is pretty simple: You have to supply enough values in your "ActionLink" that will fulfill your Route. Example:
<%= Html.ActionLink("Click Here", "ViewDetails", "Plot", new { name="my-plot-name" }, null)%>
If you leave out the "name=" part of the ActionLink method, then the RouteEngine won't see this link as being good enough to "match"... so then it would go to the default route.
This code above will make the URL look the way you want it.
How about this code-fix? (Note the name = null, appened to the end of the 4th line....)
routes.MapRoute(
"PlotByName",
"plot/{name}",
new { controller = "Plot", action = "ViewDetails", name = null }
);
and this should be renamed.. (notice plotName is renamed to name)
public ActionResult ViewDetails(string name ) { ... }
does that help?
