Hi How can I set focus to a textbox after messagebox on chrome browser?
I used some ways but without success

C#

if (MessageBox.Show("are you sure to delete?", MessageBoxButton.OKCancel) == MessageBoxResult.Cancel)
          {
              Textbox.Focus();
              System.Windows.Browser.HtmlPage.Plugin.Focus();
              this.Focus();

              Dispatcher.BeginInvoke((ThreadStart)delegate
              {
                  Textbox.Focus();
              });
              return;

              Textbox.Focus();
              this.Focus();

          }

Return statement will give you compilation warning.
ThreadStart formally and accidentally match, but this is not a purpose of this delegate type. Use, say
BegingInvoke(new System.Action({} => { TextBox.Focus(); }));
(It won't solve the problem but would look more adequate; the signature of the delegated method could be anything.)

If you want to focus on Textbox, at least don't focus anything else. Also, you can set logical focus before calling MessageBox; the focus will return to logical focus, because the message window will disappear.
