    Hello Sandeep,

    In order to remove all nodes from a DropDownTree, you can call its EmbeddedTree NodeCollection's Clear() method as shown below:

    If you want to remove the nodes based on a selection made in another DropDownTree you can use its OnEntryAdded server-side event and call the method posted above in its handler.
