I have a button which add individualSearch partial view and individualSearch partial view also have a add button which adds individualSearcharacteristic partial view in it.
I want to bind BMRTestData model with individualSearch partial so that i can get the characteristic partial view data. So i store that data in IndividualSearch's list public List<Characteristic> Characteristics { get; set; } = new List<Characteristic>();
Please guide me to do same as i am new to .net .

Update
You can add onclick event in Add Search Individual button:
<button id="add-search-individual" type="button" class="btn btn-success" onclick="addSearch(this)">Add Search Individual</button>
Add an action in controller to return IndividualSearchPartial partial view:
[HttpPost]
public ActionResult IndividualSearchCharacteristic()
{
IndividualSearch individualSearch = new IndividualSearch() { };
return PartialView("IndividualSearchPartial", individualSearch);
}
Here is all the js in main view:
#section Scripts
{
<script>
function add(element){
var action = ' #Url.Action("NewIndividualSearchCharacteristic", "Default")';
$.post(action)
.done(function (partialView) {
$(element).parents('#individual-details').find("#Characteristics").append('<div class="form-group">' + partialView + '</div>');
ResetName();
});
}
function addSearch(element){
var action = ' #Url.Action("IndividualSearchCharacteristic", "Default")';
$.post(action)
.done(function (partialView) {
$(element).parents('.mb-3').find('#searchindividuals').append('<div class="form-group search">' + partialView + '</div>');
ResetName();
});
}
function ResetName() {
var index = 0;
$(".search").each(function () {
var nameIndex = 0; var valueIndex = 0;
$(this).find(":input[type='hidden']").each(function () {
$(this).removeAttr("name");
});
$(this).find(":input[type='text']").each(function () {
if ($(this).attr("name").indexOf("Characteristics") > -1 && $(this).attr("name").indexOf("Name") > -1) {
$(this).attr("name", "IndividualSearches[" + index + "].Characteristics[" + nameIndex + "].Name");
nameIndex++;
return;
}
if ($(this).attr("name").indexOf("Characteristics") > -1 && $(this).attr("name").indexOf("Value") > -1) {
$(this).attr("name", "IndividualSearches[" + index + "].Characteristics[" + valueIndex + "].Value");
valueIndex++;
return ;
}
if ($(this).attr("name").indexOf("IndividualSearches") > -1) {
$(this).attr("name", "IndividualSearches[" + index + "].SearchPostcode");
return;
}
});
index++;
})
}
</script>
}
After submit, it will enter into following action to receive BMRTestData data:
[HttpPost]
public IActionResult TestData(BMRTestData bMRTest)
{
return View();
}
Here is the test result:

How to display .cshtml content based on ActionLink in .NET MVC?

My Register.cshtml page contains both Patient and Doctor registration. I have written a script to check if the user is Patient then displays only information relevant to patient and vice-versa.
If click on register patient then patient information only should insert into the database and the vice-versa for doctor registration.
Currently, If I register patient then it should not take specialization data into database because it is doctor's specific information.
Another problem is that, If I change the specialization or city value from drop down then it throws error:
The ViewData item that has the key 'Specialization' is of type
'System.String' but must be of type 'IEnumerable'.
Exception Details: System.InvalidOperationException: The ViewData item
that has the key 'Specialization' is of type 'System.String' but must
be of type 'IEnumerable'.
Source Error: #Html.DropDownListFor(x
=> Model.Specialization, Model.Specializations, htmlAttributes: new { #class = "form-control form-control-sm" })

I think the best way to solve it write two register action(doctor,Patient)that doctor and Patient have own view

How to fix 'System.Data.SqlClient.SqlException' error in ASP.NET MVC?

I have problem uploading videos in ASP.NET MVC. I m using HttpPostedfile base class to upload videos and I have a model for my videos to add extra field. I'm getting this error and don't know how to fix it.
The error I am getting is;
System.Data.SqlClient.SqlException: Procedure or function 'sAddNewVideoFile' expects parameter '#CourseName', which was not supplied.
Here is my code
Model
namespace eLearning.Models
{
public class FileModel
{
public int ID { get; set; }
public string Name { get; set; }
public Nullable<int> FileSize { get; set; }
public string FilePath { get; set; }
public int CourseID { get; set; }
public string CourseName { get; set; }
}
}
Controller
public ActionResult UploadVideos()
{
return View();
}
[HttpPost]
public ActionResult UploadVideos(HttpPostedFileBase fileupload)
{
if (fileupload != null)
{
var file = new FileModel();
string fileName = Path.GetFileName(fileupload.FileName);
int fileSize = fileupload.ContentLength;
int Size = fileSize / 1000;
fileupload.SaveAs(Server.MapPath("~/VideoFileUpload/" + fileName));
int CourseId = file.CourseID;
string CourseName = file.CourseName;
string CS = ConfigurationManager.ConnectionStrings["DefaultConnection"].ConnectionString;
using (SqlConnection con = new SqlConnection(CS))
{
SqlCommand cmd = new SqlCommand("sAddNewVideoFile", con);
cmd.CommandType = CommandType.StoredProcedure;
con.Open();
cmd.Parameters.AddWithValue("#Name", fileName);
cmd.Parameters.AddWithValue("#FileSize", Size);
cmd.Parameters.AddWithValue("#FilePath", "~/VideoFileUpload/" + fileName);
cmd.Parameters.AddWithValue("#CourseID", CourseId);
cmd.Parameters.AddWithValue("#CourseName", CourseName);
cmd.ExecuteNonQuery();
}
}
return View();
}

The error can point out that the CourseName is null, try change it to:
cmd.Parameters.AddWithValue("#CourseName", CourseName ?? "");
if null is not allowed you have to check your model binder or model validation.

mabey about CourseName value if CourseName is null change it to string.Empty!

ActionResult:
[HttpPost]
public ActionResult AddCompany(MainModel mainModel)
{
try
{
Country_Bind();
if (ModelState.IsValid)
{
dp obj = new dp();

Country code:
public void Country_Bind()
{
DataSet ds = dblayer.Get_Country();
List<SelectListItem> coutrylist = new List<SelectListItem>();
foreach (DataRow dr in ds.Tables[0].Rows)
{
coutrylist.Add(new SelectListItem { Text = dr["CountryName"].ToString(), Value = dr["CountryID"].ToString() });
}
ViewBag.Country = coutrylist;
}

You are currently calling the Country_Bind() method as the first statement inside your httppost action method. You actually need to do that when you want to rerender the dropdown list when re rendering the same view.
If you are not doing an ajax post,You should follow the PRG pattern. On successful save of the data, you should redirect to the GET action method which render the view. If the Modelstate validation fails, that is when you return the same view (so that you can show the validation message to user) and you need to repopulate the dropdown data before that.
When you do a Redirect, ViewData does not work to transfer messages.Use TempData instead.
[HttpPost]
public ActionResult AddCompany(MainModel mainModel)
{
try
{
if (ModelState.IsValid)
{
dp obj = new dp();
if (obj.AddNewCompany(mainModel))
{
TempData.Message = "Company added successfully";
return RedirectToAction("CompanyList");
}
}
// We need to repopulate the data needed for rendering dropdown
Country_Bind();
return View(mainModel);
}
catch(Exception ex)
{
// to do : Make sure to log the error
return View("Error");
}
}
In your case, when you do an ajax post returning a redirect result does not makes sense. You may return the url to the next page if needed as part of a json response and use that in your ajax calls success/done event handler and do appropriate things (redirect to the new page/show a message to user)
[HttpPost]
public ActionResult AddCompany(MainModel mainModel)
{
try
{
if (ModelState.IsValid)
{
dp obj = new dp();
if (obj.AddNewCompany(mainModel))
{
return Json(new { Message="Company added successfully"});
}
}
return Json(new { Message="Validation errors!"});
}
catch(Exception ex)
{
// must log the exception
return Json(new { Message="Error "});
}
}
Make sure to update your success/done event handler of your ajax call to read the response (the json and do something like showing message to user/hiding or showing the next tab)
I also noticed an issue with your ajaxifying code. Since you are making an ajax form submission, you should prevent the default form submit behavior by calling the event.preventDefault method.
$("#SaveCompany").click(function (e) {
e.preventDefault();
GetInfo();
});
I would also recommend to use a flat-lean view model specific for the view. So your properties will not be nested level and when you use the helper methods (TextBoxFor etx), It will generate the correct input field names and you do not need to manually build the Js object you want to send. You may simply use the jquery serialize() method on your form object and send that as the data for the ajax call.

Adding roles in the create user view ASP Identity MVC

I´m writing a project to manage a pool of users of asp.net identity 2.0, and i want to create a user and add roles to the user in the same view, so when i post the model just simple create the user and add the roles in the same action.
I don't know how to generate the roles list for the user, for example i have a dropdownlist for with the roles and id´s and my view is something like this
<div class="form-horizontal">
<div class="col-md-6">
<div class="panel panel-info">
<div class="panel-heading">Datos personales</div>
<div class="panel-body">
<div class="form-group">
<div class="col-md-4">
#Html.DisplayNameFor(m => m.User.Nombre)
</div>
<div class="col-md-8">
#Html.TextBoxFor(m => m.User.Nombre, new { #class = "form-control" })
</div>
</div>
<div class="form-group">
<div class="col-md-4">
#Html.DisplayNameFor(m => m.User.Apellido)
</div>
<div class="col-md-8">
#Html.TextBoxFor(m => m.User.Apellido, new { #class = "form-control" })
</div>
</div>
<div class="form-group">
<div class="col-md-4">
#Html.DisplayNameFor(m => m.User.DependenciaId)
</div>
<div class="col-md-8">
#Html.DropDownListFor(m => m.User.DependenciaId, new SelectList(ViewBag.ListaDependencia, "Id", "Descripcion"), "Ninguno", new { #class = "form-control" })
</div>
</div>
</div>
</div>
</div>
<div class="col-md-6">
<div class="panel panel-info">
<div class="panel-heading">Datos usuario</div>
<div class="panel-body">
<div class="form-group">
<div class="col-md-4">
#Html.DisplayNameFor(m => m.User.UserName)
</div>
<div class="col-md-8">
#Html.TextBoxFor(m => m.User.UserName, new { #class = "form-control" })
</div>
</div>
<div class="form-group">
<div class="col-md-4">
#Html.DisplayNameFor(m => m.User.NetUser)
</div>
<div class="col-md-8">
#Html.TextBoxFor(m => m.User.NetUser, new { #class = "form-control" })
</div>
</div>
</div>
</div>
</div>
<div class="panel panel-info">
<div class="panel-heading">Datos usuario</div>

<table>
Here must present the roles to add to the user

I found a way
first a helper for offline collections, that a i found on internet
public static class HtmlPrefixScopeExtensions
{
private const string idsToReuseKey = "__htmlPrefixScopeExtensions_IdsToReuse_";
public static IDisposable BeginCollectionItem(this HtmlHelper html, string collectionName)
{
if (html.ViewData["ContainerPrefix"] != null)
{
collectionName = string.Concat(html.ViewData["ContainerPrefix"], ".", collectionName);
}
var idsToReuse = GetIdsToReuse(html.ViewContext.HttpContext, collectionName);
var itemIndex = idsToReuse.Count > 0 ? idsToReuse.Dequeue() : Guid.NewGuid().ToString();
var htmlFieldPrefix = string.Format("{0}[{1}]", collectionName, itemIndex);
html.ViewData["ContainerPrefix"] = htmlFieldPrefix;
// autocomplete="off" is needed to work around a very annoying Chrome behaviour whereby it reuses old values after the user clicks "Back", which causes the xyz.index and xyz[...] values to get out of sync.
html.ViewContext.Writer.WriteLine("<input type=\"hidden\" name=\"{0}.index\" autocomplete=\"off\" value=\"{1}\" />", collectionName, html.Encode(itemIndex));
return BeginHtmlFieldPrefixScope(html, htmlFieldPrefix);
}
public static IDisposable BeginHtmlFieldPrefixScope(this HtmlHelper html, string htmlFieldPrefix)
{
return new HtmlFieldPrefixScope(html.ViewData.TemplateInfo, htmlFieldPrefix);
}
private static Queue<string> GetIdsToReuse(HttpContextBase httpContext, string collectionName)
{
// We need to use the same sequence of IDs following a server-side validation failure,
// otherwise the framework won't render the validation error messages next to each item.
var key = idsToReuseKey + collectionName;
var queue = (Queue<string>)httpContext.Items[key];
if (queue == null)
{
httpContext.Items[key] = queue = new Queue<string>();
var previouslyUsedIds = httpContext.Request[collectionName + ".index"];
if (!string.IsNullOrEmpty(previouslyUsedIds))
foreach (var previouslyUsedId in previouslyUsedIds.Split(','))
queue.Enqueue(previouslyUsedId);
}
return queue;
}
private class HtmlFieldPrefixScope : IDisposable
{
private readonly TemplateInfo templateInfo;
private readonly string previousHtmlFieldPrefix;
public HtmlFieldPrefixScope(TemplateInfo templateInfo, string htmlFieldPrefix)
{
this.templateInfo = templateInfo;
previousHtmlFieldPrefix = templateInfo.HtmlFieldPrefix;
templateInfo.HtmlFieldPrefix = htmlFieldPrefix;
}
public void Dispose()
{
templateInfo.HtmlFieldPrefix = previousHtmlFieldPrefix;
}
}
then using an editor template
<tr>
#using (Html.BeginCollectionItem("ListaObraSocialPrepagasSeleccionadas"))
{
<td>
<input type="radio" name="RolesUserTableRadio" />
#Html.HiddenFor(model => model.Id, new { #readonly = "readonly" })
</td>
<td>
#Html.HiddenFor(model => model.Id, new { #readonly = "readonly" })
#Html.DisplayTextFor(model => model.Name)
</td>
}
a partial view to manage the list
<script type="text/javascript">
$(document).ready(function () {
$("#btnAddRoles").click(function () {
var rolId = $("#ddRoles").val();
if (rolId == null || rolId == '') {
alert("Debe seleccionar un rol.");
return;
}
var foundRol = $("#RolesUserTable").find("input[value='" + rolId + "']");
if (foundRol.size() > 0) {
alert("Ya se ha agregado el rol.");
return;
}
$.ajax({

});
});
$("#btnDeleteRoles").click(function () {
var myRadio = $('input[name=RolesUserTableRadio]');
var radio = myRadio.filter(':checked');
if (radio.size() == 0) {

return;

if (!confirm("¿Confirma que desea eliminar el rol seleccionado?")) {
return;

<table id="RolesUserTable" class="table table-striped">

and finnaly the dropdown and the table
<div class="form-group">
