I am trying to access the selected node value and text when i double click on node

Javascript function

function SetPlaceHolders(sender, args) {
        var TreeView = $find("<%=RadTreeView_CommonControls.ClientID%>");
        var SelectedNode_Tree = TreeView.get_selectedNode();
        SelectedNode_Tree = TreeView.SelectedNode;
        debugger;

    }

var SelectedNode_Tree = TreeView.get_selectedNode(); //This is displaying Null


        SelectedNode_Tree = TreeView.SelectedNode; // This raising as Undefined


Will u please help me to fnd out this?

Hello Bhuvan,

Try the following code snippet to get the selected node.

Java Script:

<script type="text/javascript">
    function SetPlaceHolders(sender, args) {
        debugger;
        var TreeView = $find("<%=RadTreeView_CommonControls.ClientID%>");
        var SelectedNode_Tree= TreeView.get_selectedNodes()[0].get_text();
    }
</script>

Thanks,
Princy.

Hello rajaganapathi,

Here is another way to access the text or value of a node:

function SetPlaceHolders(sender, args) {
          var SelectedNode_Tree = args._node.get_text();
          alert(SelectedNode_Tree);
      }

As a matter of fact the option that was offered by Mr. Princy Philip worked fine as well in my simple project.

Hope this works for you.
