Disabling contextmenu on a certain folder/file

[Claude]

Hie everyone,

I have a project with different permissions. I would like to disable contextmenu on a certain folder based on the permissions. I have tried using OnClientItemSelected to no avail. Any assistance will be greatly appreciated.

Regards,
Claude

Hi Claude,

You can cancel the menus by attaching handlers to the corresponding RadMenu controls (for the RadGrid and RadTreeView) and then cancel the menu using args.set_cancel(true) method

1. Attach the handlers in codebehind:
   

   RadFileExplorer1.TreeView.OnClientContextMenuShowing = "OnClientContextMenuShowing";
   RadFileExplorer1.GridContextMenu.OnClientShowing = "OnGridContextShowing";

2. Cancel the context menus:
   

   function OnClientContextMenuShowing(oTreeView, args)
   {
       args.set_cancel(true);
   }
   function OnGridContextShowing(oMenu, args)
   {
       args.set_cancel(true);
   }

I hope this helps.


Kind regards,
