I have the following code:
#using (Html.BeginForm("FolderChange", "EdiSender", FormMethod.Post, new {id = "ediFilesForm"}))
{
var directoriesSelectList = new SelectList(Model.Directories);
#Html.DropDownListFor(m => m.SelectedDirectory, directoriesSelectList, new {#Id = "Directories",
#style = "width:Auto;", #size = 20, onchange = "$('#ediFilesForm').submit()", name = "action:FolderChange"})
var ediFilesSelectList = new SelectList(Model.EdiFileNames);
#Html.DropDownListFor(m => m.SelectedEdiFile, ediFilesSelectList, new {#Id = "EdiFileNames",
#style = "width:Auto;", #size = 20})
}
<br/>
<form action="" method="post">
<input type="submit" value="Send" name="action:Send" />
<input type="submit" value="Delete" name="action:Delete" />
<input type="submit" value="Refresh" name="action:Refresh" />
</form>
Here is a part of the controller:
[HttpPost]
[ActionName("FolderChange")]
public ActionResult FolderChange(EdiFileModel ediFileModel)
{
ediFileModel = Load(ediFileModel.SelectedDirectory);
return View("Index", ediFileModel);
}
...
[HttpPost]
[MultipleButton(Name = "action", Argument = "Send")]
public ActionResult Send(EdiFileModel ediFileModel)
{
....
return View("Index", ediFileModel);
}
[AttributeUsage(AttributeTargets.Method, AllowMultiple = false, Inherited = true)]
public class MultipleButtonAttribute : ActionNameSelectorAttribute
{
public string Name { get; set; }
public string Argument { get; set; }
public override bool IsValidName(ControllerContext controllerContext, string actionName, MethodInfo methodInfo)
{
var isValidName = false;
var keyValue = string.Format("{0}:{1}", Name, Argument);
var value = controllerContext.Controller.ValueProvider.GetValue(keyValue);
if (value != null)
{
controllerContext.Controller.ControllerContext.RouteData.Values[Name] = Argument;
isValidName = true;
}
return isValidName;
}
}
When I press any of the buttons, I get the following message:
The current request for action 'FolderChange' on controller type 'EdiSenderController' is ambiguous between the following action methods:
System.Web.Mvc.ActionResult Send(EdiSimulatorWebSender.Models.EdiFileModel) on type EdiSimulatorWebSender.Controllers.EdiSenderController
System.Web.Mvc.ActionResult FolderChange(EdiSimulatorWebSender.Models.EdiFileModel) on type EdiSimulatorWebSender.Controllers.EdiSenderController
Could you please help me understand what is wrong with my view?
Thanks.
make sure on your controller you add the post attribute to your post method
public ActionResult FolderChange ... for the get
[HttpPost]
public ActionResult FolderChange... for the post

I want to use #AjaxExtensions.ActionLink(AjaxHelper, String, String, String, RouteValueDictionary, AjaxOptions) in cshtml file (ASP.Net 6 MVC).
#model List<Shift>
#using System.Web.Mvc.Ajax;
#{
AjaxOptions deleteOptions = new AjaxOptions()
{
InsertionMode = InsertionMode.Replace,
UpdateTargetId = "table"
};
}
#foreach (Shift shift in Model)
{<td>
#AjaxExtensions.ActionLink( ???,"Delete", "DeleteShift", "MainDoctor", new{id=shift.Id}, deleteOptions)
</td>
}
As this document said, AjaxExtensions.ActionLink is only applies to ASP.NET MVC 5.2, and the correct usage should be:
#Ajax.ActionLink("Delete", "DeleteShift", "MainDoctor", new { id = shift.Id }, deleteOptions)
In ASP.NET 6, you need use an alternative way like below:
<a data-ajax="true" data-ajax-mode="replace" data-ajax-update="#table" data-ajax-url="#Url.Action("DeleteShift", "MainDoctor", new { id = shift.Id})">Delete</a>
A simple working demo you could follow:
Model:
public class Test
{
public string Id{ get; set; }
}
View(Views/Home/Index.cshtml):
#model Test
<div id="table">
#Model.Id
<a data-ajax="true" data-ajax-mode="replace" data-ajax-update="#table" data-ajax-url="#Url.Action("DeleteShift", "MainDoctor", new { id = 1 })">Delete</a>
</div>

Result:
I am trying to access my page at: https://localhost:44319/Analyze/Index/6
The problem is that my drop down list always selects the first item in the list instead of the one provided by ID. While stepping through the debugger, before the View() is returned, I see that the SelectList was populated correctly.
AnalyzeController.cs
public IActionResult Index(int? Id)
{
return Index(Id ?? getStatementEndingById(Id).StatementEndingId);
}
[HttpPost]
public IActionResult Index(int StatementEndingId)
{
var statementEnding = getStatementEndingById(StatementEndingId);
ViewBag.StatementEndingId = new SelectList(
_context.StatementEnding.OrderByDescending(s => s.StatementEndingId),
"StatementEndingId",
"Name",
statementEnding);
return View(getPayments(statementEnding));
}
private StatementEnding getStatementEndingById(int? statementEndingId)
{
StatementEnding statementEnding;
if (statementEndingId.HasValue)
{
statementEnding = _context.StatementEnding.FirstOrDefault(s => s.StatementEndingId == statementEndingId);
}
else
{
statementEnding = _context.StatementEnding.OrderByDescending(s => s.StatementEndingId).FirstOrDefault();
}
return statementEnding;
}
Setting DropDownList in Razor
#Html.DropDownList("StatementEndingId", null, new { #class = "form-control mb-2 mr-sm-2" })
I am using ASP.NET Core 2.1.
Any suggestions are much appreciated. Thanks in advance.
First i would recomend to create a typed model, something like this one :
public class StatementViewModel
{
public int StatementEndingId { get; set; }
public List<SelectListItem> StatementEndings { get; set; }
}
Second fill the Model with all dropdown options (StatementEndings) and the selected one (StatementEndingId)
public IActionResult Index()
{
var model = new StatementViewModel();
model.StatementEndingId = getStatementEndingById(Id).StatementEndingId;
model.StatementEndings = _context.StatementEnding.OrderByDescending(s => s.StatementEndingId).Select(p => new SelectListItem() { Text = p.Name, Value = p.StatementEndingId }).ToList();
return View(model);
}
And for the last, in the view
#model StatementViewModel
#Html.DropDownListFor(m => m.StatementEndingId, Model.StatementEndings, null, new { #class = "form-control mb-2 mr-sm-2" })
I've looking all over for something similar, couldn't find nothing..
I'm using ASP.NET MVC 4. I'm building a page so the users in my app can manage the permissions associated with each role.
So i have a view with #htmlDropDownList to show all the available roles, and below, one #Html.CheckBox for each Permission of the role wich is selected above.
The first time the view is rendered, the checkboxes are all set to true or false, according to the permission of that role.All is fine, life is good :) . When the value of the drop is changed, i post the SelectedRoleId using $.ajax. Then, i fetch all the permissions of the new selected role.
While in debug, in the razor view, i can confirm the new values (true or false) inside the model are correct. The problem is that the checkboxes show the old values, before the role was changed..
This is my first question asked, so i'll have to apologize if the question is not being made the best way.
And thx in advance to all of you :)
So here's my Controller:
public ActionResult Index(int ? SelectedRoleId)
{
ManagePermissionsViewModel model = new ManagePermissionsViewModel();
if (SelectedRoleId == null)
{
model.SelectedRoleID = 1; // value 1 is the supervisor Role
}
else
{
model.SelectedRoleID = SelectedRoleId;
}
//values for the dropdownlist of Roles
var items = from x in db.UserRoles
select x;
model.RoleList = new SelectList(items, "Id", "DESCRIPTION");
//gets all the permissions of the selected role
model.EntirePermissionList = (from k in db.Permissions
select new Permission
{
IdPermission = k.Id,
PermissionDescription = k.Description,
IsSet = db.RolePermissions.Any(n => n.RoleId == model.SelectedRoleID && n.PermissionId == k.Id),
PermissionGroupId = (int)k.PermissionGroupId
}).ToList();
//Gets all the groups of Permissions
model.ListPermissionGroups = (from l in db.PermissionGroups
select new PermissionGroup
{
Id = l.Id,
Description = l.Description
}).ToList();
return View(model);
}
[HttpPost]
public ActionResult Index(FormCollection form) {
switch (form["SubmitButton"])
{
case "Save":
SavePermissions();
break;
default:
return RedirectToAction("Index", new RouteValueDictionary(new { controller = "ManagePermissions", action = "Index", SelectedRoleId = Convert.ToInt32(form["SelectedRoleId"]) }));
}
return View();
}
And here is my View:
'#model AML.Web.Models.ManagePermissionsViewModel
#using (Html.BeginForm("Index", "ManagePermissions", FormMethod.Post, new { id = "MyForm" }))
{
#Html.Label("Role :", htmlAttributes: new { #class = "control-label col-md-2" })
#Html.DropDownList("RoleId", Model.RoleList, new { id = "RoleId" })
<div>
#foreach (var item in Model.ListPermissionGroups)
{
<h3> #item.Description</h3>
foreach (var permission in Model.EntirePermissionList.Where(n => n.PermissionGroupId == item.Id))
{
<h5>
#permission.PermissionDescription
#Html.CheckBox("Chk_Permisssion", permission.IsSet)
</h5>
}
}
</div>
<input type="submit" value="Save" name="SubmitButton" class="btn btn-default" />
}
#section Scripts {
<script type="text/JavaScript">
$(document).ready(function () {
$("#RoleId").change(function (e) {
e.preventDefault();
$.ajax({
url: "/ManagePermissions/Index",
cache: false,
type: "POST",
data: { 'SelectedRoleId': $(this).val() },
dataType: "json",
success: function (result) { console.log("Sucess!"); },
error: function (error) { console.log("Error!"); }
})
});
});
</script>
}
And my viewModel:
public class ManagePermissionsViewModel
{
public int? SelectedRoleID { get; set; }
public string SelectedRoleDescription { get; set; }
public SelectList RoleList { get; set; }
public List<Permission> EntirePermissionList { get; set; }
public List<PermissionGroup> ListPermissionGroups { get; set; }
}
public class Permission
{
public int IdPermission { get; set; }
public bool IsSet { get; set; }
public string PermissionDescription { get; set; }
public int PermissionGroupId { get; set; }
}
public class PermissionGroup {
public int Id { get; set; }
public string Description{ get; set; }
}
UPDATE 1 -
Well, i think i got it. Let me post my approach
In the View:
#Html.DropDownListFor(n => n.SelectedRoleID, Model.RoleList,null,
new { onchange = "document.location.href = '/ManagePermissions/Index?SelectedRoleId=' + this.options[this.selectedIndex].value;" })
<div>
#foreach (var item in Model.ListPermissionGroups)
{
<h3> #item.Description</h3>
foreach (var permission in Model.EntirePermissionList.Where(n => n.PermissionGroupId == item.Id))
{
<h5>
#permission.PermissionDescription
<input type="checkbox" id="#permission.IdPermission" checked="#permission.IsSet">
</h5>
}
}
</div>
And in the Controller:
public ActionResult Index(int? SelectedRoleId)
{
ManagePermissionsViewModel model = new ManagePermissionsViewModel();
ModelState.Clear();
if (SelectedRoleId == null)
{
model.SelectedRoleID = 1;
}
else
{
model.SelectedRoleID = SelectedRoleId;
}
var items = from x in db.UserRoles
select x;
model.RoleList = new SelectList(items, "Id", "DESCRIPTION");
model.EntirePermissionList = (from k in db.Permissions
select new Permission
{
IdPermission = k.Id,
PermissionDescription = k.Description,
IsSet = db.RolePermissions.Any(n => n.RoleId == model.SelectedRoleID && n.PermissionId == k.Id),
PermissionGroupId = (int)k.PermissionGroupId
}).ToList();
model.ListPermissionGroups = (from l in db.PermissionGroups
select new PermissionGroup
{
Id = l.Id,
Description = l.Description
}).ToList();
ModelState.Clear();
return View(model);
}
Now each time the Drop changes value, the permissions in the checkboxes are updated. I got it to work with the attribute on the drop, "on change = Document.location.hef = URL". Is this a good approach? Or should i use something like ajax request ?
UPDATE 2
The Controller:
public async Task<ActionResult> Index(int? SelectedRoleId)
{
if (SelectedRoleId == null)
{
SelectedRoleId = 1;
}
var model = await GetSelectedPermissions(SelectedRoleId);
return this.View("Index",model);
}
[HttpGet]
public async Task<ActionResult> GetPermissions(string Id)
{
var SelectedRoleId = int.Parse(Id);
var model = await this.GetSelectedPermissions(SelectedRoleId);
return PartialView("_ManagePermissions", model);
}
private async Task<ManagePermissionsViewModel> GetSelectedPermissions(int? SelectedRoleId)
{
ModelState.Clear();
ManagePermissionsViewModel model = new ManagePermissionsViewModel();
model.SelectedRoleID = SelectedRoleId;
var items = from x in db.UserRoles
select x;
model.RoleList = new SelectList(items, "Id", "DESCRIPTION");
model.EntirePermissionList = await (from k in db.Permissions
select new Permission
{
IdPermission = k.Id,
PermissionDescription = k.Description,
IsSet = db.RolePermissions.Any(n => n.RoleId == model.SelectedRoleID && n.PermissionId == k.Id),
PermissionGroupId = (int)k.PermissionGroupId
}).ToListAsync();
model.ListPermissionGroups = await (from l in db.PermissionGroups
select new PermissionGroup
{
Id = l.Id,
Description = l.Description
}).ToListAsync();
return model;
}
The View
<h2>Permissions - Ajax with Partial View</h2>
#using (Html.BeginForm("SaveData", "ManagePermissions", FormMethod.Post, new { id = "MyForm" }))
{
#Html.Label("Role :", htmlAttributes: new { #class = "control-label col-md-2" })
#Html.DropDownListFor(n => n.SelectedRoleID, Model.RoleList, null, null)
<div id="target">
#Html.Partial("~/Views/Shared/_ManagePermissions.cshtml", Model)
</div>
<input type="submit" value="Save" name="SubmitButton" class="btn btn-default" />
}
#section Scripts {
<script type="text/javascript">

var SelectedRoleID = $("#SelectedRoleID").val();
$("#target").load('#(Url.Action("GetPermissions","ManagePermissions",null, Request.Url.Scheme))?Id=' + SelectedRoleID);
});
});
</script>
}
And the Partial View:
<div>
#foreach (var item in Model.ListPermissionGroups)
{
<h3> #item.Description</h3>
foreach (var permission in Model.EntirePermissionList.Where(n => n.PermissionGroupId == item.Id))
{
<h5>
#permission.PermissionDescription
<input type="checkbox" id="#permission.IdPermission" checked="#permission.IsSet">
</h5>
}
}
</div>
I've been trying to pass a model to a partial view with a form. Some of the model fields are already assigned in the GET request. When the form loads I can see the model fields values but after
submiting the form I get this error in this line: #Html.Hidden("From",Model.From):
Object reference not set to an instance of an object
Why these two fields are assigned with null on submit?
My controllers:
[HttpGet]
public ActionResult SendPrivateMessage(string from, List<string> to)
{
// two of the fields are already assigned
return PartialView("SendMessage", new MessageModel(from,to));
}
[HttpPost]
public ActionResult SendPrivateMessage(MessageModel m)
{
string fullname = "";
LoginModel loginData = (LoginModel)(Session["user"]);
if (Session["user"] != null)
{
fullname = loginData.LoginDS.Tables[0].Rows[0][loginData.LoginDS.Tables[0].Columns["fullname"].Ordinal].ToString();
}
m.fullname = fullname;
m.Send();
return PartialView("SendMessage");
}
The partial view:
#model HaifanetMobile.Models.MessageModel
<div id="contact_form">
<a id="back_contact" href="#" style="float:left">
<img style="height:20px; width:30px;" src="~/Images/back_btn.gif" alt="back" />.

The Model:
public class MessageModel
{
public string From { get; set; }
public List<string> To { get; set; }
public string Subject {get; set;}
public string Content { get; set; }
public string fullname { get; set; }

ServiceReference2.WebService1Soap ws = new ServiceReference2.WebService1SoapClient();
if (!ws.SendMessage(this.From, this.Content, this.Subject, this.To.ToArray() ,this.fullname))
throw new Exception();
}
}
Thanks in advance
You're forgetting to pass the model to your view.
When you return this view, instead of this:
return PartialView("SendMessage");
you must do this:
return PartialView("SendMessage", m);
Where m is your model. That's why the model is null inside your view.
I am trying to use a variation of the code from this page:
Multiple button in MVC
But everytime I click on the buttons it goes to the index actionresult method and not one of the button methods. Index is the view name but the button clicks are happening in a partial view called "P_NewPersonForm.cshtml"
P_NewPersonForm.cshtml
#using (Html.BeginForm())
{
<div id="divClaimType">
#Html.Label("Claim type:")
#Html.DropDownListFor(m => m.modelClaim.ClaimType, new List<SelectListItem>
{
new SelectListItem{ Text="Legal", Value = "Legal" },
new SelectListItem{ Text="Immigration", Value = "Immigration" },
new SelectListItem{ Text="Housing", Value = "Housing" }
})
</div>
<div id="divClaimStatus" style="padding: 5px;">
#foreach(var item in Model.LinkerStatusOfClaim)
{
#Html.Label("Claim status:")
#Html.DropDownListFor(m => m.LinkerStatusOfClaim[0].ClaimStatusID, new SelectList(Model.modelClaimStatus, "ClaimStatusID", "ClaimStatus"))
#Html.LabelFor(m => m.LinkerStatusOfClaim[0].Notes)
#Html.TextAreaFor(m => m.LinkerStatusOfClaim[0].Notes)
#Html.LabelFor(m => m.LinkerStatusOfClaim[0].StartDate)
#Html.TextBoxFor(m => m.LinkerStatusOfClaim[0].StartDate, new { #id = "datepicker", #Value = DateTime.Now, #readonly = true, Style = "background:#cccccc;" })
<br />
#Html.ValidationMessageFor(model => model.LinkerStatusOfClaim[0].StartDate)
<br />
}
<input type="submit" value="Add another status to this claim..." name="action:add"/>
<input type="submit" value="Delete status." name="action:remove"/>
#* #Ajax.ActionLink("Add another status to this claim...", "AddClaim", "Client", new AjaxOptions { HttpMethod = "POST"})*#
</div>
}
</div>
I have one button for adding to the collection of claims and another to remove one from the collection.
ClientController
public ActionResult Index()
{
var Model = new modelPersonClaim();
// Add one item to model collection by default
LinkerStatusOfClaim LinkerStatusOfClaim = new LinkerStatusOfClaim();
Model.LinkerStatusOfClaim.Add(LinkerStatusOfClaim);
DataLayer.RepositoryClient RC = new RepositoryClient();
Model.isValidModel = true;
RC.GetClaimTypes(Model, PersonTypes.NewPerson.ToString());
return View(Model);
}
[HttpPost]
public ActionResult P_NewPersonForm(modelPersonClaim Model)
{
DataLayer.RepositoryClient RC = new RepositoryClient();
RC.GetClaimTypes(Model, PersonTypes.NewPerson.ToString());
Model.isValidModel = ModelState.IsValid;
if (ModelState.IsValid)
{
RC.CreatePerson(Model);
Model.SuccessfulInsert = true;
Model.InsertString = "Person data has been successfully inserted into the database.";
if (Model.modelClaim.ClaimMade)
{
RC.CreateClaim(Model);
}
}
else
{
Model.SuccessfulInsert = false;
Model.InsertString = "Person data could not be inserted into the database. Missing key fields.";
}
return View("Index", Model);
}
[AttributeUsage(AttributeTargets.Method, AllowMultiple=false, Inherited = true)]
public class MultiButtonAttribute : ActionNameSelectorAttribute
{
public string Name { get; set; }
public string Argument { get; set; }
public override bool IsValidName(ControllerContext controllerContext, string actionName, MethodInfo methodInfo)
{
var isValidName = false;
var keyValue = string.Format("{0}:{1}", Name, Argument);
var value = controllerContext.Controller.ValueProvider.GetValue(keyValue);
if (value != null)
{
controllerContext.Controller.ControllerContext.RouteData.Values[Name] = Argument;
isValidName = true;
}
return isValidName;
}
}
[HttpPost]

public ActionResult AddClaimStatus(modelPersonClaim Model)
{
Model.LinkerStatusOfClaim.Insert(Model.LinkerStatusOfClaim.Count, new LinkerStatusOfClaim());
return View("Index", Model);
}
[HttpPost]
[MultiButtonAttribute(Name = "action", Argument = "Delete status.")]
public ActionResult RemoveClaimStatus(modelPersonClaim Model)
{
// Can't remove IF only 1
if (Model.LinkerStatusOfClaim.Count == 1)
{
}
else
{
Model.LinkerStatusOfClaim.RemoveAt(Model.LinkerStatusOfClaim.Count);
}
return View("Index", Model);
}
When I click one the buttons it hits the public override bool IsValidName twice. Once for each button. But then because the action name is always index, it goes to the index method and not one of the button methods.
Does anyone have any ideas how to fix this?
Something is wrong with this part:
var keyValue = string.Format("{0}:{1}", Name, Argument);
var value = controllerContext.Controller.ValueProvider.GetValue(keyValue);
Your attribute is this:
[MultiButtonAttribute(Name = "action", Argument = "Add another status to this claim...")]
So in that case keyValue will become: "action:Add another status to this claim..." while your HTML states: <input type="submit" value="Add another status to this claim..." name="action:add"/>, so I think Argument in your attribute should be add.
