title: WPF - call a window function from a child page
body: <p>I have WPF window that uses a dockpanel and the menu control. I have the code to create the menu options based on a user ID.</p>
  
  <p>Within this window, I have a frame that contains a WPF page. I carry out all the authentication on the page and then have a user ID for the window to use. However, I cannot get the parent window to "refresh" and create the menu bar with the new ID information. When the window loads, I do not run through the commands to display the menu bar. I have tried putting that in its own, public, function and calling it from the page but that does not seem to work. </p>
  
  <p>There must be a window method that I'm missing that can make the menu bar display based on the call from the page.</p>
