We need your feedback, because we are considering changes in the release approach for Telerik UI for ASP.NET Core. Please provide your feedback in the comments section below:


1. Is it hard to understand the version numbers of our releases? If yes, what makes them hard to understand them?

2. Would semantic versioning (SemVer) of our releases make it easier to understand our version numbers and what's behind them?

3. If we go with SemVer, we might need to start with version 3000.0.0 as we currently use 2022.x.x. Please share your thoughts about this approach and ideas for what number versioning would work best for you.

Hi!

The ListView is breaking my web application, and I cannot make head or tail of the reason:

An unhandled exception occurred while processing the request.

NotSupportedException: "ClientTemplateId or ClientTemplateHandler" cannot be null or empty.

Kendo.Mvc.UI.ListView<T>.VerifySettings()

 

Also, you demos for the ListView are broken and the browser tab crashed after a while.

I need an urgent fix, as this is affecting the live application.

In our UI for ASP.NET Core R3 2020 (2020.3.915) release, the Column menu message of unsticking a column is "null".

This bug will be resolved in our next official release.

In the meantime, as a workaround, manually set the Unstick Column menu message:

.ColumnMenu(c => c.Messages(m => m.Unstick("Unstick Column")))

Hello,

I want to show, group and filter the Id field on one of the grid columns by connecting it to the Enum side.

I used ForeignKey column but it doesn't show the data.

The request is being sent. data is returning. But it doesn't show.

Important Note: I don't use inline editing on the grid. It'll only show.

What's wrong?

I have an AutoComplete control calling my Controller that has the [Authorize] attribute applied to it. When the session expires the control lets you still type in it and tries to call the controller. Nothing happens on the page to show an issue, but in the browser development tools console, there is a jQuery error reporting a 404 error.

The big question is why is it not either getting a 401 error code or following the redirect it is getting to go to the login page? If it was reporting the correct error code than at least I could capture it and redirect it myself or deal with it as I need to.

I am trying to filter through a model lets say:

 

public class Cat

{    

     public int Id {get; set;}

     public int ColorId {get; set; }

}

public class Color

{

    public int ColorId { get; set; }

    public string? Color { get; set; }

}

 

in the controller :

 

public IActionResult GetCatsColors([DataSourceReques] DataSourceRequest request)

{

    var catColor = (from c in _catContext..Cats.ToList()

                              join v in _colorContext.Colors.ToList() on c.ColorId equals v.ColorId

                              select new ColorCat

                             {

                                   Colori = v.Color,

                                   CatId = c.Id

                             }).ToList();

                var jsonCat = catColor.ToDatasourceResult(request);

                return Json(jsonCat);

}

 

the view:

 

 @(Html.Kendo().Grid<TelerikOrderBossProduction.ViewModels.ColorCat>()

      .Columns(col =>

      {

             col.Bound(t => t.Id);

             col.Bound(t => t.Colori);

     }

     .Filterable(f => f.Mode(GridFilterMode.Row))

     .etc

 

    Now when I try to filter through the Id I get the grid to respond but when I filter by Colori I do not get a response

    and I have noticed, Error 500. Server internal error.

 

   I also have tried creating a view in the database but the same result appears. It looks like it only filters from one class but not the other.

 

  ArgumentException: Invalid property or field - 'Colori' for type: Cat

We are trying to implement the Kendo grid to replace our previous framework tool (c1).

Now I am stuck on creating a particular grid. The grid has a group header over 2 columns. In a row, the data of a property is represented as a cell (span) over 2 columns. Below this span are 2 properties in their own cell. This almost succeeds me with a ClientTemplate. However, I do not know how to use the properties from the row data.
When the group header is clicked the first propery sorts. The headers of 2 other columns sort their own property (column). 
In the picture, "naam" is the groups head. "Adres" and "Plaats" are the subcolumns.

How can I make this with the Kendo grid? I am mainly concerned with sorting the data behind the group header.

I have a grid whose first column is a string column, and the 2nd and 3rd columns are sometimes dropdowns based on the value shown in the first column.

I have it mostly working except for a small issue. If I click slowly enough it seems to work but if i click around the different cells eventually my dropdown appears in a cell that it should not. What is the correct way to implement the described behavior?

Should I be looking for a cell template solution? Or do I need to subscribe to a custom grid event?

Any advice would be much appreciated.

Below code needs to be corrected for ASP.NET Core Grid Popup Editing : 

https://demos.telerik.com/aspnet-core/grid/editing-popup?autoRun=true&theme=default-main-dark

.DataSource(dataSource => dataSource .Ajax() .PageSize(20) .Events(events => events.Error("error_handler")) .Model(model => model.Id(p => p.ProductID)) .Create(update => update.Action("EditingPopup_Create", "Grid")) .Read(read => read.Action("EditingPopup_Read", "Grid")) .Update(update => update.Action("EditingPopup_Update", "Grid")) .Destroy(update => update.Action("EditingPopup_Destroy", "Grid"))

 

It seems create arrow function is called for update & destroy as well.

while editing the row data EditingPopup_Create create is called instead of update !!
