    I have RadTreeView which supports drag and drop facilty. But I want to allow drag drop only within the tree nodes and not anywhere else in the page.

    As currently Drag and Drop of Tree View is on th whole page which should not be the case and because of this application is getting crash throwing a follwoing error.

    Application - Manage App Menu Screens(Presentation)System.NullReferenceException: Object reference not set to an instance of an object.

       at Administration_Application_ManageAppMenuScreens.RadTreeView1_HandleDrop(Object sender, RadTreeNodeDragDropEventArgs e) in c:\Redux_Code\net\web\Administration\Application\ManageAppMenuScreens.aspx.cs:line 105

    Can any one help me in solving this problem?
