Hi Telerik Support
Facing an issue with Keyboard navigation in Telerik Grid component.
When we use TAB to navigate, the grid header gets focus only for the first time. After completing one round of navigation, second time after the Toolbar buttons, if we TAB out, focus goes to the pager sections skipping the grid header part.
Pls refer the REPL sample from Telerik website:
Steps to reproduce:
1) Use ALT + W and then use TAB key to navigate
2) First focus goes to the Toolbar button (Add Product), then goes to the Grid Header and then if we TAB again focus goes to the Pager section
3) After the Pager section, if we do steps 1 and 2 again, we can see that it skips the Grid Header focus second time onwards.
I am trying to add aggregation to the grouping and display them in the group footers. I am successfully returning the aggregated values but they are not displayed in the GroupFooterTemplate.
Using CheckBoxList filtering changes the filter menu for all columns. I would like to specify CheckBoxList only for certain columns, but that doesn't currently appear to be an easy option.
1) Leave as FilterMenuType "Menu" but implement a custom filter template for the columns I want. That would be the most obvious, but CheckBoxList is not a usable control on its own?
2) Or do the inverse, use FilterMenuType "CheckBoxList" and implement a custom filter template for all the columns where I don't want to use that. Seems like a lot of extra work to manually recreate default filters.
3) I guess I roll my own clone of the CheckBoxList control and use that like #1 on individual columns?
Any chance the CheckBoxList control could be publicly exposed for direct use?
I need to lock the "expand" column in the Grid(Locked=true).
When I scroll horizontally, the first column with the expand/collapse icon scrolls out of view. I would like a way to lock it.
When initial grouping is set through the state, the GroupFooterTemplate does not render. One has to perform some action for refreshing the Grid in order to display the template - for example, collapsing/expanding a group.
For reference, the GroupHeaderTemplate renders correctly.

The GroupFooterTemplate renders with a delay after the Grid. A possible workaround for the time being is to refresh the Grid after it has been initialized to ensure the GroupFooterTemplate will be displayed.
Grid with columns price1 and price2. Enter value in price1, switch to price2, enter value there, and editor is set to old value after async events finish.
The value entered in price2 is correctly set to the property, but the editor reverts to the previous value. If you escape edit mode of the cell, the value entered before the events finish will be shown.
On (fast) tabbing and entering values, this removes the first values entered before the async background events finish.
I tried reproducing the problem in REPL, but could not get the exact same behaviour. In our case no specific value is being set to price2, it just reverts.

How would you approach preventing the editor from being overridden by other cells' delayed events?
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);
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.

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

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.

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.
