The controls work but I cannot view them in designer I get an error:
Error 1 Content1:Type 'System.Web.UI.UserControl' does not have a public property named 'Title'. D:\asp.net\Atlas\SampleWebSite\ModalPopup\ModalPopup.aspx D:\...\SampleWebSite\
I saw another post that said to rebuild, but I tried that and it didn't work.
Nevermind... found the answer to remove the collapible panels. Wait until next release.
