Hello Raja,

Based on your requirement, I guess its is easy to handle the RadMenuItems in RadMenu's client event. Here is the approach that you can try.

    Attach 'OnClientShowing' event to RadContextMenu and check for the selecteditems' count in the handler. Now based on the count, access the menu item and set it disabled/enabled. You can use the findItemByValue/findItemByText/findItemByUrl methods to get reference to menu items.

Also the following docuemnatation shows more on the client methods and poropeties.

RadMenu and RadContextMenu objects

A sample code is shown below:

function OnClientShowing(sender, args) {

var master = $find("<%=RadGrid1.ClientID %>").get_masterTableView();

if (master.get_selectedItems().length > 1) {

alert('Disable some items');

}

}

Cheers,

Shinu.
