Clicking a command button on my grid and running the code the handler contains causes all command buttons in that row to disappear. Refreshing the page makes them reappear.

Perhaps I am not using it correctly.

     <TelerikGridCommandButton Command="Edit" OnClick="@OpenRequestEditWindow" Icon="edit">Edit</TelerikGridCommandButton>
     <TelerikGridCommandButton Command="Delete" OnClick="@DeleteRequestItem" Icon="delete">Delete</TelerikGridCommandButton>

Clicking the "Edit" button opens a window with controls on it. User edits the values in the controls and has a save button 

  <TelerikButton Icon="save" OnClick="@UpdateRequest">Save Purchase Request</TelerikButton><br /><br />

This event simply writes to the database and then rebinds the grid data.

 var grid = await service.GetRequests();
 RequestAddGrid = grid.ToList();

If you have those buttons in a command column, then firing the Edit or Delete commands have definitive meaning of their own in the grid, and you must, indeed, use different names for custom commands.
