Scenario #1

I want my users to confirm the update of a cell value with the built-in Confirmation Dialog for Blazor. If I use the keyboard (Enter, Tab) to close the edit the Confirmation dialog will popup, but after closing it the Grid hangs. 

Scenario #2

If I edit a cell and press enter very quickly, the grid is not able to get the new value inserted after confirming it through the dialog.

Scenario #3

If you press Enter very quickly to confirm the value for deletion, the value is not always removed.

Hello

What is the purpose of this (https://docs.telerik.com/blazor-ui/components/grid/selection/overview#row-drag-and-drop);

Row Drag and Drop

If the user drags selected rows, the current row selection will be cleared on row drop.

Is this a bug? As when you select multiple rows, then drag and drop the rows, it clears the bound selectedItems object (but the rows still remain ticked in the UI). Just confirming this is something that will be fixed?

Cheers

When using the Filter Menu inside the Column Menu filter value is reset if Rebind is called. For reference, if using FIlter Row or a standalone Filter Menu value is not reset upon invoking Rebind.

Reproduction: https://blazorrepl.telerik.com/mdOJYHas48vPCPUv47.

Are there any plans to have the datagrid be both groupable and draggable?

Thanks,

Andy

The value of the FileName parameter is not updated properly in the OnBeforeExport event handler.

In this example.  Select a cell in column C.  Then double click on another cell in column C.  The unhandled exception will show up and a null reference exception is logged in the console.  

https://blazorrepl.telerik.com/QHuSQBlj170zO4u130

The exception message is:

System.InvalidOperationException: TelerikValidationComponent requires a cascading parameter of type EditContext. You can use Telerik.Blazor.Components.TelerikValidationTooltip`1[System.String] inside a EditForm or TelerikForm.

I am binding a Grid to a collection of ExpandoObjects. In the collection, there are decimal values. When I try to add Aggregates for the decimal values the Grid throws an exception. 

<AdminEdit>

As a workaround, you can cast the decimal values to double instead.

Hello,

I'm having issues trying to figure out how to change values (from the model) when I'm Incell Mode without triggers the OnRead events after.  The actual code is working great since I was able to remove the Incell mode on the OnChangeModel event below,  but OnRead is keeps call after (which I didn't need and slow user experience)

Is there a way to cancel the OnRead ?

 <TelerikGrid OnRead="ReadItems" EditMode="GridEditMode.Incell"
                     @ref="@GridRef">
    <GridColumns>
      <GridEditDropDownColumn Field="Test1" Data="@Eval?.ListEvaluationTypes" Title="Title" Width="130px" OnChange="OnChangeModel" />
    </GridColumns>
</TelerikGrid>

   private TelerikGrid<EvaluationListDTO> GridRef { get; set; }

   protected async Task OnChangeModel(object model)
        {
            var item = (EvaluationListDTO)model;

            var state = GridRef?.GetState();

           //Save in the Database  

                // use the state to remove the edited item (close the editor)
                state.EditItem = null;
                state.OriginalEditItem = null;
                await GridRef.SetStateAsync(state);
        }

===ADMIN EDIT===

Currently, we use groups for calculating all aggregates in Grid. We can optimize the process so that when there are no groups, specific aggregates are still calculated.

The problem is when filtering programmatically, the X that is normally used to clear the search box disappears.
I am following the Telerik guide here. https://docs.telerik.com/blazor-ui/components/grid/filter/searchbox

The problem is actually demonstrated in the example from that page.

Thanks.

When you combine frozen column with row selection and horizontal scrolling is applied (due to column and grid widths), column content are not hidden under frozen columns when a row is selected, as seen bellow in lines 2,3 and 4.

Checkbox, Product Name & Command columns are frozen. "Quantity per Unit" values are clearly visible behind frozen "Product Name" values. You can find a test scenario here (Telerik REPL for Blazor).

All themes suffer from this issue except Fluent theme. With default and bootstrap themes it happens on all odd selected lines and with material theme it happens on all selected lines.

The Blazor TelerikGrid component should support a dropdown column.  It should be exactly the same as the dropdown column in the Ajax grid.
