keyboard left/right expand collapse operations

[mirang]

The radtreeview node expands and collapses both using left arrow key and right arrow key. Is there a way to restrict the user to expand only using right key and collapse using left key, other than handling javascript events?

Hi Mirang,

 
The only way to achieve this functionality is to use the onClientKeyPressing event and cancel it the appropriate cases.
