Yes.

OwnedWindow ownedWindow = new OwnedWindow();
ownedWindow.Owner = this;
ownedWindow.Closing += new System.ComponentModel.CancelEventHandler(ownedWindow_Closing);
ownedWindow.Show();

This handler should be in owner window.

void ownedWindow_Closing(object sender, System.ComponentModel.CancelEventArgs e)
{

}
