List Item Filter Web part error

Oct 30, 2009 at 12:49 PM


I'm very new to sharepoint development and have been looking for some way of doing what the list item filter web part does. I have installed the product sucessfully and activated it however when I try to configure the web part on an .aspx page I get the following error

"RegisterRequiresControlState can only be called before and during PreRender"

The only option available is to click cancel.

I would be grateful for any help.
