Good morning,

I'been trying to get help and seems like you guys respond very well at the beginning and then just disappearing.

My company which I work for has a license but I downloaded version 11.1(i had 7.3 version) this is I need it to test my Web appication on Windows7 IE9 which will be installing throug out my company soon.

I change all assembly and references from v7.3 to v11.1 and worked fine on my local machine but when I deploy on development server I received error on very first infragistics control in the application:

 Parset Error Message:The base class includes the field 'UltraWebMenu1', but its type (Infragistics.WebUI.UltraWebNavigator.UltraWebMenu) is not compatible with the type of control (Infragistics.WebUI.UltraWebNavigator.UltraWebMenu).

Thanks so much for your help.
