Hi Deep,

Actually "local" should reference the namespace where the CustomDragDropBehavior class is placed. You should define it in the Page tag. Here is an example:

xmlns:local="clr-namespace:Final.Telerik.Windows.Examples.GanttView.Programming.DragResizeConfigurator"

Hello ,
I read your reply.It gives me error in CLr "Undefined clr namespace"

 xmlns:local="clr-namespace:Final.Telerik.Windows.Examples.GanttView.Programming.DragResizeConfigurator"
