I have an "UltraWebMenu" on my master page and when I create a new page in VS2008 and inherit that masterpage I get:
"Error Creating Control" The string 'ignav:ignav:Item" conatins too many device filters. There can be only one.
Does anyone know how to fix this? Everything works, it is just annoying to see that error in my Design view.
Hi,
This issue is common for any custom control in Visual Studio 2008 - it is infact a bug in Visual Studio 2008. The problem is when there are multiple different tag prefixes defined for the same namespace (i.e. Infragistics.Web.UI.ListControls). Using one tagprefix for all controls defined in a namespace is a possible workaround.
I hope this helps,
Angel
