WPF set attached event programmatically

How do you do this programmatically in WPF?

<window Validation.Error="ItemError"></Window>

I am trying to set the attached event for Validation.Error through code, but cannot quite figure out how to do it.

Solution

  • You use Validation.AddErrorHandler to do this:

    Validation.AddErrorHandler(this, this.ItemError);
