CollapsiblePanelExtender, programatically collapse a panel

Hi joee,

You should check outFAQ Item #19.

Thanks,
Ted

The FAQ says to do this:

CollapsiblePanelProperties properties = cpe.GetTargetProperties(Panel1);
if (properties != null)
{
properties.ClientState = collapsed.ToString().ToLower();
properties.Collapsed = collapsed;
}

However, unless I'm missing something, cpe does not have the methods GetTargetProperties (did this change recently?). I'm trying this:

cpe.Collapsed = true;
cpe.ClientState = "true";

Which is syntactically valid, but nothing happens after the postback. Is there something on the client side that you're supposed to do?

Yes, the FAQ entry is a bit out of date. Your translation seems valid - make sure you're using the 61121 release since we fixed something related there.

I can confirm that this does *not* work:

cpe.Collapsed = true;

Code gets executed but the panel does not collapse. I'm usingversion 1.0.61121.0.

Cheers,

Note that there are two steps above, not just one. Also, please refer to the ToolkitTests\Manul\ClientStateLifecycle.aspx page for an example of this in action.
Thanks David. Yes, I was running a slightly older copy (1.0.61106.0). I pulled down 61121, dropped in the new dll and it seems to be working fine with the syntax I mentioned above. I guess with this kind of stuff I have to check more often than every month or two for updates :)
