Collapsing/Expanding CollapsiblePanelExtender Programatically

I ran into the problem of collapsing my CollapsiblePanelExtender programatically. This is a quick solution to that for those running into the same problem.

Here is the code:

this.cpeTest.ClientState = "true";
this.cpeTest.Collapsed = true;

And here is the control information:

<ajaxControlToolkit:CollapsiblePanelExtender
    id="cpeTest"
    runat="server"
    TargetControlID="pnlTarget"
    Collapsed="False"
    ExpandControlID="divExpand"
    CollapseControlID="divCollapse"
    AutoCollapse="False"
    ScrollContents="False"
    TextLabelID="lblExpand"
    CollapsedText="Expand"
    ExpandedText="Collapse"
    ExpandDirection="Vertical" />

I hope this helps :).

CollapsiblePanelExtender Flicker

I noticed that when I used the CollapsiblePanelExtender, it had a tendancy to flicker once when the page loads. Here is my quick fix for that. All you have to do is add these properties to the panel's definition:

style="overflow:hidden" Height="0"

I hope this helps.
