Question

I’ve got the following Generic usercontrol declared:

public partial class MessageBase<T> : UserControl     {         protected T myEntry;         public MessageBase()         {             InitializeComponent();         }         public MessageBase(T newEntry)         {             InitializeComponent();             myEntry = newEntry;         }         } } 

But the compiler won’t allow me to do this:

public partial class MessageControl : MessageBase<Post> {     public MessageControl()     {         InitializeComponent();     } } 

How do I create a generic user control in C#?

Answer 1

Try this

public partial class MessageControl : MessageControlBase {         public MessageControl()         {         InitializeComponent();         } }  public class MessageControlBase : MessageBase<Post> {} 

The key to getting the designer to work is that the base class of the class you are editing must not be generic.
