     We have a radtreeview with check boxes. Now we want to support radcontextmenu on checked items and dragdrop on selected items. But when we implement context menu , we are getting even on selected item.

    How can we disable contextmenu on selected item and enable only if it checked. Please provide your inputs.

    Hello Subhashini,

    You can prevent the context menu from opening by handling the ContextMenuOpening event of the element on which the menu is attached. For example, if the context menu is attached on the RadTreeView control you can subscribe for its event and set the argument's Handled property to True. Here is an example:
    <telerik:RadTreeView ContextMenuOpening="RadTreeView_ContextMenuOpening">
                <!-- menu items -->

    private void RadTreeView_ContextMenuOpening(object sender, ContextMenuEventArgs e)
        if(the item is selected and is not checked)
            e.Handled = true;           

    Please try this approach and let me know if it works for you.
