Upon further examination,it might have something to do with dnn5 changing the id's of any server objects.

My literal's id goes from "test" to "dnn_test".  Is there a way to keep this from happening?

I had the same problem and had no clue what was wrong with my code. Then I googled and I came across this post.

I have found the solution to my problem. Apparently, if you add the Page_Load Event into a script section in the ascx file in Visual Studio, Visual Studio doesn't add the Handles Me.Load part of the Event Signature.

 Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
 End Sub

After adding the red marked part everything worked fine.

Maybe this helps.

Kind Regards,
