Hello,

I'm trying to open a popup editor for a grid that resides inside a kendoWindow.  I can open the window and display the grid.  I can also have an "Add New" button on the grid's toolbar that works, and adds new content to the grid, however, the edit and delete buttons on each row of the grid are not clickable (nothing happens when I click them).

My grid resides inside <div> tags that I open as a kendoWindow via a JavaScript function.

Here's my grid markup:

Why won't the edit/delete command of a kendo Grid buttons work inside the kendoWindow?

Any help is appreciated.  Thanks.

Grid content shown as undefined all the cells of the grid after upgrade to .Net core 3.0.

I can see the data sent properly from Controller Action, Please see the attached document.

I was required to change my controller action (as part of .Net core 3.0 upgrade)From: return Json(datatable..ToDataSourceResult(request)); To: return Json(datatable.AsEnumerable().ToDataSourceResult(request));

I am attempting to invoke the Kendo mvc extensions from an automated test.

It builds fine, but at runtime I get an exception when I invoke Kendo.Mvc.Extensions.QueryableExtensions.ToDataSourceResult(...)

The exception is:

System.IO.FileNotFoundException : Could not load file or assembly 'Microsoft.AspNetCore.Mvc.Abstractions, Version=3.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. The system cannot find the file specified.
   at Kendo.Mvc.Extensions.QueryableExtensions.ToDataSourceResult

I am running this in both .NET Framework 4.6.2 and .NET Core 3.0. It works fine in .NET Framework, it's just the .NET Core build which fails.

Here is the complete .csproj file:

I can't find where to indicate the model i.e what's the equavalent of  @(Html.Kendo().Grid<Model> in the TagHelper syntax.

Without the model I can't get intellisense for my grid columns and inferred column names (DataAnnotation) are missing.

Can i set a default preset filter value for a grid at runtime? 

I'd like to add a isEqualTo value from jquery or similar

.Filter(f => f.Add(a => a.OperatorID).IsEqualTo( ? ))

Hi, 

I want to bind a label to a combobox using the tag '<label asp-for="test"></label>'.

I followed the online demo example exactly and it didn't work.

Is this a bug in the code for .NET CORE? 

Hi,

I am using the scheduler but would like to pass the entered values in the scheduler (name, description, etc) to my C# controller, ideally within the kendo code in my view.

Could someone advise how to do this? I need to invoke a C# controller method on creation of an appointment.

I am a complete newbie to Kendo UI. I am trying to follow the getting started exercise https://docs.telerik.com/aspnet-mvc/helpers/data-management/grid/binding/custom-binding

Step 1

public ActionResult Index([DataSourceRequest(Prefix = "Grid")] DataSourceRequest request)

{

    IQueryable<Order> orders = new NorthwindEntities().Orders;

}

It does not recognise Prefix = "Grid".   The type of namespace 'Prefix' could not be found.

I cannot work out what namespace I need to resolve this.

Any help greatly appreciated.

I am using core 2.2 , VS 2017 and Kendo-UI 2019.3.1023
