Get number of nodes

[Giorgos]

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.

JavaScript:

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

Thanks,
Shinu.

Hello ,

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

I didnt get any option for it.

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.
