Specifying DataTemplate.DataType with a custom type extension

Question

I have this markup extension

public class NullableExtension : TypeExtension
{
    public NullableExtension() {
    }

    public NullableExtension( string ty         


        

Answer 1

The syntax

DataType="{x:Type TypeName=System:Nullable`1[[System.Int32]]}">

doesn't seem to work for user defined types :(

Actually one other way is to create a base non-generic type. Set first data template to that type and bind ContentPresenter.Content to the property which holds object of T. Then create other data templates for whatever T.
