Experimenting with dynamic skins, I've created a skin which, based on browser loads a browser based skin (control).
It all appears to work but i am using try ..catch to load the browser based skin as a control and although it loads, it always throws an exception:
The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
Checking for <% .. %> in the browser based skin, i have even stripped it down to just a content pane but i still get the same error. i think much of the issue is that both the main/redirect skin and the browser based skin seem to need the reference to <%@ Control ..... "skins.vb" ... > to function properly and to render the contentPane and other panes.
where is this error coming from?
redirect.ascx

try
Controls.Add(LoadControl("layouts/" + device + ".ascx"))
catch ex as Exception
