Where is Button.DialogResult in WPF?

Question

In System.Windows.Forms.Button there is a property DialogResult, where is this property in the System.Windows.Controls.Button (WPF)?

Answer 1

Just make sure that you've shown the form using ShowDialog rather than Show. If you do the latter you'll get the following exception raised:

InvalidOperationException was unhandled

DialogResult can be set only after Window is created and shown as dialog.
