title: Message box with Image in WP7
body: <p>Hi at present I am using a grid with Image and two Buttons for showing a custom message box in my WP7 application whose visibility is collapsed at first. All is working fine but I have to disable all the controls behind on the page when its visibility is visible. So its quite a overhead to enable/disable lots of control behind.</p>
  
  <p>Is there a better solution for my requirement which are :(1) To show a message box having image and two button or textbox and (2) It should appear in the middle of page.</p>
  
  <p>Thanks in advance!!</p>
