Collapse SlidingZone inside an update panel.

[Kyle]

Hello,

I have an iframe surronded by an update panel.  In my iframe i load, there is a SlidingZone that I use ExpandedPanelID to expand the one RadPane I have inside the sliding zone.  Inside the Pane is a Tree and when a user clicks on a node in the tree I want the slidingzone to close.  I've seen solutions to this but they all utilize javascript like so:

 var slidingZone = $find("<%= SlidingZone1.ClientID %>");
         slidingZone.UndockPane(paneid);

I can't use the "$find("<%= SlidingZone1.ClientID %>")" inside an updatepanel.  Is there another way to close a slidingzone either with javascript or code behind?

thank you.

Hi Kyle,
I am not quite sure why you cannot use the code with an UpdatePanel. In case you get the "The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>). " error, you can wrap the code in a RadCodeBlock:

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
<script type="text/javascript">
function Test()
{
    var slidingZone = $find("<%= SlidingZone1.ClientID %>");
}
</script>
</telerik:RadCodeBlock>

In case you do not want to use that approach, you can clear the DockedPaneId property of the RadSlidingZone on the server:

<telerik:RadSplitter ID="RadSplitter1" runat="server">
    <telerik:RadPane ID="RadPane1" runat="server" Width="22px" Scrolling="None">
        <telerik:RadSlidingZone ID="RadSlidingZone1" runat="server">
            <telerik:RadSlidingPane ID="RadSlidingPane1" runat="server" Title="Aaa"></telerik:RadSlidingPane>
        </telerik:RadSlidingZone>
    </telerik:RadPane>
    <telerik:RadPane ID="RadPane2" runat="server">
    </telerik:RadPane>
</telerik:RadSplitter>
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" />

protected void Button1_Click(object sender, EventArgs e)
{
    this.RadSlidingZone1.DockedPaneId = string.Empty;
}
