I've already tried: Header="{Binding Path=DataContext.MyProperty, RelativeSource={RelativeSource Self}} Header="

问题 I'm using WPF's regular DataGrid inside a custom control. One of the DataGrid's cell template content should be bound to a the Text of a Textblock or to a DependencyProperty on the custom control.
