Question

Is it possible to inherit from both ViewPage and ViewPage<T>?? Or do I have to implement both. Currently this is what I have for ViewPage. Do i need to repeat myself and do the same for ViewPage<T>??

    public class BaseViewPage : ViewPage     {         public bool LoggedIn         {             get             {                 if (ViewContext.Controller is BaseController)                     return ((BaseController)ViewContext.Controller).LoggedOn;                 else                     return false;             }         }     }

Create both versions:

public class BaseViewPage : ViewPage {      // put your custom code here }  public class BaseViewPage<TModel> : BaseViewPage where TModel : class {     // code borrowed from MVC source      private ViewDataDictionary<TModel> _viewData;      [System.Diagnostics.CodeAnalysis.SuppressMessage('Microsoft.Usage', 'CA2227:CollectionPropertiesShouldBeReadOnly')]     public new ViewDataDictionary<TModel> ViewData {         get {             if (_viewData == null) {                 SetViewData(new ViewDataDictionary<TModel>());             }             return _viewData;         }         set {             SetViewData(value);         }     }      protected override void SetViewData(ViewDataDictionary viewData) {         _viewData = new ViewDataDictionary<TModel>(viewData);          base.SetViewData(_viewData);     } } 

then

public class MyCustomView : BaseViewPage { }  or  public class MyCustomView : BaseViewPage<MyCustomViewData> { }
