ANY insight on the reason this error is occuring??

When you put a control in an ASPX file, a corresponding field whose name is the same as the control's ID is automatically created in the generated class. So the generated class has two fields with the same name and different types, which is illegal. You need to change the name either of the control, or of the DataGridPagerStyle.

I had similar issue.  The issue fixed by changing 'CodeFile' tag to 'CodeBehind' tag in the ascx file.  I guess this affects how .net compiles the app and hence was throwing error.

I had the same message with a user control inheriting from a generic class.

The base class includes the field 'uxContactDetailsView', but its type (ClassName`1[[Namespace.GenericType, AssemblyNamePrefix.AssemblyName, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]) is not compatible with the type of control (ASP.contactdetailsview_ascx)

 The "ClassName`1[[blahblahblah, blah, blah, blah]]" is how to declare the generic type in the Inherits attribute of the <%Control Language = "C#" ... > tag - apparently it doesn't understand the C# "ClassName<MyGenericType>" syntax, and needs to use the CLR syntax ("ClassName`1[[MyGenericType]]")

Turns out the user control wasn't in a namespace (so it assumed I wanted to use "ASP" as the namespace?) - and giving this class file a namespace solved the problem.

 So the user control .ascx file now starts with <% Control Language = "C#" Inherits = "MyNamespace.MyType`1[[MyGenericNameSpace.MyGenericType, MyDll, Version=1.0.0.0., Culture=null, PublicKeyToken=null]]" CodeBehind = "MyCodeFile.ascx.cs" %>
