Incompatible with MVC

ASP.NET Framework Features That Are Incompatible with MVC

Because ASP.NET MVC does not maintain state information by using view state, you must find other ways to manage state information, if you need it. In addition, server controls that rely on view state and postback will not work as designed in an ASP.NET MVC application. Therefore, you should not use controls such as the GridView, Repeater, and DataList controls.

The life cycle of a Web Forms page is complex, during which many events occur. These events are not supported in an ASP.NET MVC application, because the interactions between the model, view, and controller use a different life-cycle model. For more information about the MVC life-cycle model, see Understanding the MVC Application Execution Process.
