    Is there any way to get the number of nodes an object of type RadDropDwonTree contains?

    Hi Giorgos,

    I guess you want to access the number of nodes in the RadDropDownTree. Please check the following JavaScript code.

    <script type="text/javascript">
        function getNodeCount() {
            var raddropdowntree = $find('<%=RadDropDownTree1.ClientID %>');
            alert("Count " + raddropdowntree.get_embeddedTree().get_allNodes().length);

    Hello ,

    I need same functionality to count the number of nodes in raddropdowntree from serverside.

    I didnt get any option for it.

    also can not set the value by selectedIndex

    Hello Sandeep,

    In order to get the Nodes count you can still use the Embedded TreeView control of the DropDownTree, but at server-side. In addition, regarding the SelectedIndex that you need to set - you can access the NodesCollection (index-based) of the Embedded TreeView and use the SyncEmbeddedTree method.

    In the attachment you can find a simple example demonstrating the above suggested approaches.

    Hope this would help.
