Disable collapse/expand in treeview

[Lubomir]

Hello,
i want to disable this functionality - expand and collapse. When i loaded my tree I using tree.ExpandAllNodes().
After that i hidden buttons(checkboxes) for this activity, but now they are invisible but they work.

Hi Lubomir,

I suppose you want to disable collapsing of the RadTreeNode. Try canceling collapsing in the OnClientNodeCollapsing event of RadTreeView.

ASPX:

<telerik:RadTreeView ID="RadTreeView1" runat="server" OnClientNodeCollapsing="OnClientNodeCollapsing">
    <Nodes>
      ...............
    </Nodes>
</telerik:RadTreeView>

JS:

<script type="text/javascript">
    function OnClientNodeCollapsing(sender, args) {
        args.set_cancel(true);
    }
</script>

Hope this helps.

Regards,
Princy.
