Hello,

I have an ajax bound grid and I have it set to be sortable.  But when I click a column heading all of the data in the grid disappears.  If I switch it to server binding the sorting works.  I need ajax binding because I am using a client detail template.  What am I missing??

Here is the view:



Here are the relevant controller methods:

Hello,

I'm a bit new to the MVC pattern and the Telerik ASP.NET MVC controls.  I've been working with ASP.NET Ajax for years now, but not the MVC stuff.  I finally had the opportunity to work on something MVC based, and find myself stuck already.  

I have a hierarchical menu driven by a stored procedure.  The procedure basically removes / disables items that a user doesn't have rights to based on a role and other information that's passed into the proc.  I'd like to implement its use in a partial view, but cant' for the life of me figure this out.  This may be more of a MVC question than a Menu specific question, but anyone can point me at an example that would be awesome.  

I've tried the sample applications generated by the Telerik template, but that uses a static menu in the _Layout file.  Not exactly what I want.

Thank you for your help!

I am using asp.net mvc grid with server wrappers and have 4 cascading dropdowns by utilizing custom editors.  I am using inline editing with the grid.  The grid is ajax and the dropdowns also get their data via ajax/json.

I am experiencing 2 symptoms which may or may not be related to the same problem:

1) When a change is made to the first dropdown, it's value is updated correctly in the database but the grid does not refresh.  I found this article but it didn't correct my issue. Simply hitting refresh on the page shows the new/correct value.  

2) The dropdowns are cascading correctly (ie when one is changed, the others get the correct choices).  However, only the first dropdown (not the cascaded ones) are updated correctly in the database.  The other's values are not updated.

Here's the Controller code that does the update:
Here's the grid cshtml:
Here's custom editor along with javascript:

I have the following code to bind a DropDownList for the Status property of a User Model. The Status is an enum.

The DropDownList for the first user (row 1 in the table) is rendered correctly - however subsequent rows the DropDownList is not rendered - it is rendered as an empty text box. If I use 'Vanilla Razor' DropDownList then the controls are rendered correctly - what is wrong?

Thanks

I am using asp.net mvc4 using kendo ui to complete my project i have few textboxes which should is hidden and it should only be enable when there is no record for the studentID . I am using autocomplete when a user enters the studentid then it searches the existing ids but i want to customize it so that if there is a unique id then only textboxes will be enable i am new here in asp.net mvc so please help me out help would be appreciated thanks

I am trying to conditionally disable fields in a grid popup editortemplate based on a value in the passed in Model.  The value is correct in the model if I use an Html helper like a hidden field, but if I try to access it using razor code it is not there.  I assume this has to do with the order of how things are loading but I'mm not sure how to fix it.  Here is the editortemplate code:


When I view the source I can see that the hidden for Model.Status has the correct value but when I try to set the razor variable so I can use it to display the fields disabled, it does not have the value at all.

What am I missing? 

Good afternoon. My Kendo Grid allows me to create new records, but when I try to update a record I get the following error:

"No parameterless constructor defined for this object"

I should note that if I do not change anything when the update popup appears and just click the update button, it works fine. Only if I change something and then click update do I get the error.

Here is my grid code:



Here is the controller code:




Does anyone know what's going on here? 

Hi,

I need to attach an autocomplete to  "ManagerName" and selected manager employeeId should be populated to "EmployeeId".

CSHTML
---------
@Html.TextBoxFor(m => m.ManagerName)
@Html.TextBoxFor(m => m.EmployeeId)

JavaScript
---------------
 $(function () {

 var GetManagerURL = '@Url.Action("GetManager", "Employee", new { Area = "Employee" })';

$("#ManagerName").kendoAutoComplete({
            placeholder: "Enter your manager name",
            minLength: 3,
            dataTextField: "EmployeeName",            
            dataSource: {
                transport: {
                    read: GetManagerURL,
                    parameterMap: function (data) {
                        return {
                            input: $("#ManagerName").val(),
                            take: data.take,
                            skip: data.skip
                        };
                    }
                },               
                select: onManager_select,               
                serverFiltering: true,
                serverPaging: true,
                pageSize: 10
            }
        });

});

  function onManager_select(e) { // debugger is not hitting this function
        alert("select");
        //debugger;
        var selectedOne = $("#ManagerName").dataItem(e.item.index());
        $("#EmployeeId").val(selectedOne.EmployeeId);

    }


Controller
-------------

public JsonResult GetManager(string input, int take, int skip)
       {
            List<EmployeeViewModel> mgrList = new List<EmployeeViewModel>();
            mgrList.Add(new EmployeeViewModel() { EmployeeId = 1, EmployeeName = "Prashad" });
            mgrList.Add(new EmployeeViewModel() { EmployeeId = 2, EmployeeName = "Ashreewad" });
            mgrList.Add(new EmployeeViewModel() { EmployeeId = 3, EmployeeName = "Sathish" });
            mgrList.Add(new EmployeeViewModel() { EmployeeId = 11, EmployeeName = "Prashad1" });
            mgrList.Add(new EmployeeViewModel() { EmployeeId = 21, EmployeeName = "Ashreewad1" });
            mgrList.Add(new EmployeeViewModel() { EmployeeId = 31, EmployeeName = "Sathish1" });
            mgrList.Add(new EmployeeViewModel() { EmployeeId = 12, EmployeeName = "Prashad2" });
            mgrList.Add(new EmployeeViewModel() { EmployeeId = 22, EmployeeName = "Ashreewad2" });
            mgrList.Add(new EmployeeViewModel() { EmployeeId = 32, EmployeeName = "Sathish2" });
            mgrList.Add(new EmployeeViewModel() { EmployeeId = 13, EmployeeName = "Prashad3" });
            mgrList.Add(new EmployeeViewModel() { EmployeeId = 23, EmployeeName = "Ashreewad3" });
            mgrList.Add(new EmployeeViewModel() { EmployeeId = 33, EmployeeName = "Sathish3" });
            try
            {
                if (!string.IsNullOrWhiteSpace(input))
                {

                    if (mgrList != null)
                    {
                        mgrList = mgrList.Where(e => e.EmployeeName.ToLower().StartsWith(input.ToLower())).Take(take).ToList();
                    }
                }
            }
            catch (Exception ex)
            {
                //
                return null;
            }
            return Json(mgrList, JsonRequestBehavior.AllowGet);
        }

AutoComplete is populated fine.
But when I select an item from the populated list it is not hitting the "select" event function.

So how can we get selected Employee Object?

Thanks & Regards,

All -

I have a multiselect and I would like to clear the "selected values" and bring the control back to its default state once I click the Add button. (see images for a better understanding). When viewing the images:

1. "1-DefaultState.png" shows what the control looks like on load.
2. "2-Add Clicked.png" shows what the control looks like after I select an item and click "Add"
3. Essentially, after I click the "Add" button I want the multi select control to look like it does in the image 1-DefaultState.png" 

I have tried several options such as changing the values array to null, but nothing seems to work.

Thanks,
Andrew
