title: How to disable contextmenu except in the grid of telerik FileExplorer?
body: <p>I tried to disable unnecessary context menu when I set a grid with ContextMenus. By default, if you click the blank part of the grid, it disables the Delete menu. </p>
  
  <p>However, after adding customized menu like Download, it shows in the context menu even there is no selected item (i.e., How can I download it?). So I want to disable the unnecessary menu or make it invisible except in the grid row context menu.</p>
  
  <p>I'm using telerik ASP.NET AJAX contorl 2009 Q2.</p>
  
  <p>Thanks in advance.</p>
