ScrollIntoView When Finding Node

[Tahereh]

HI
I have a RadTreeView inside RadAjaxPanel, I also have a textbox and button inside AjaxPanel, when the user clicks the button, Server side method executes and find appropriate node according to the text in textbox and select the first item.I want to scroll to selected node and I use ScrollIntoView with the following format:

<script type="text/javascript">
function OnResponseEnd(sender, arguments)
{
      var treeviewInstance = <%=RadTreeView1.ClientID %>;
      var selectedNode = treeviewInstance.SelectedNode;
       if (selectedNode != null)
       { 
          selectedNode.ScrollIntoView();
       }
}
</script>

<radA:RadAjaxPanel
    ID="RadAjaxPanel1"
    runat="server"
    ClientEvents-OnResponseEnd="OnResponseEnd">
</radA:RadAjaxPanel>

But it doesn't work and it can not find treeviewInstance.SelectedNode. What should I do?

Thanks In Advance

Hello Tahereh,

Please make sure the TreeView has set Height and that the Node is visible before calling ScrollIntoView(). Additionally you can try to call the method with a timeout:

setTimeout(function() {selectedNode.ScrollIntoView();}, 0);

I hope this helps.

All the best,
