Mysterious Height Added to Sliding Pane

[Robert]

I've constructed a sliding pane inside of which is just a user control that contains a RadTreeView.  I've added code such that when a bottom-level node is clicked then the  RadSlidingPane collapses.  It works well except for one thing: When I then reopen the pane the height of it is suddenly much larger than before.  Please note that if I just open & close the pane without touching the treeview then this does not occur.  Here's a short video illustrating the problem: http://mwtech.com/downloads/public/ExcessiveHeight.zip

Here's the layout code:

  <telerik:RadSplitter ID="radSplitter" runat="server" LiveResize="false" Height="449">
    <telerik:RadPane ID="radPaneLeft" runat="server" Scrolling="None">
      <telerik:RadSlidingZone ID="radSlidingZone" runat="server" Width="22" ClickToOpen="true" DockedPaneId="radSlidingPane">
        <telerik:RadSlidingPane ID="radSlidingPane" runat="server" Title="Rates" Width="272" BackColor="#F0F8FF" TabView="ImageOnly" IconUrl="~/Images/hierarchy.gif">
          <asp:PlaceHolder ID="placeHolderHierarchy" runat="server" />
        </telerik:RadSlidingPane>
      </telerik:RadSlidingZone>
    </telerik:RadPane>

And here's the code to programmatically collapse the pane:

    public void CollapseHierarchyPane()
    {
      RadSlidingZone radSlidingZone = (RadSlidingZone)this.FindControl("radSlidingZone");
      if (radSlidingZone != null)
        radSlidingZone.DockedPaneId = null;
    }


Why is this occurring and how do I correct it?

Hi Robert,

I tried to reproduce the reported problem with the provided information but to no avail. Could you please provide more detailed information?

• Which version of RadControls and .NET Framework are used in the application?
• Under which browser and its version the problem occurs?
• Could you please provide a sample runnable project and / or a Live URL reproducing the problem so we can investigate it further?

In addition, if you are not using the latest version of RadControls for ASP.NET AJAX (2010.2.826) could you please upgrade to it and see if the problem still occurs?
Looking forward to hearing from you,
