Question

In my WPF xaml file, how do I make it so that my textbox uses the default button when I press the return key, but if I paste something in with more than 1 line, it pastes it all in. The AcceptsReturn parameter doesn’t let me use a default button. Is this possible?

Answer 1

WPF doesn’t have similar support as in the WinForms DialogResult property. If you want to do something when someone presses enter then you should override the OnKeyUp event or OnPreviewKeyUp event.

The AcceptsReturn property of the TextBox class just means that it will allow the user to press return and register a CRLF in the textbox (otherwise it ignores them).
