  1. ShowMessageBox(string message) - In this method we are passing message only, but the caption of the messagebox will be the lightswitch’s screen name in which we are displaying this messagebox. On the message box there will be only one button with caption Ok. Using this method you cannot change the caption of messagebox.
  2. ShowMessageBox(string message, string caption, MessageBoxOption button) – This method gives you more flexibility in terms of setting the captions and button types. Here the first parameter is for the message which you want to display, second one is to set the caption of messagebox and third one is to set the type of messagebox. The variable button i.e. third parameter is of type MessageBoxOption. On setting the value of this variable we can control which buttons to be displayed in the messagebox.
