Visual Studio 2008 DataList not visible

Im using VS 2008, and I am trying to a customize a DataList in an ascx file. The page has a SQLDataSource, a Datalist, and a very small amount of static text. When I edit the code in the .ascx page in the asp tag, say i'll add a <div> tag when I go back to Design mode the SqlDataSource, the Dat开发者_运维知识库aList and both gone, but any static content I have is still on the page. Any changes That I do make will show up if I view the page in my browser. is causing this and how do I fix this?

In case anyone is wondering here is a little article about this very topic I found.
