Cannot click on an off screen button

Jun 20, 2011 at 7:24 PM

We have a view with a slider in it that allows users to change the zoom level of the view. So it may happen for a button that automated test needs a click goes off screen. But  then when I invoke Button.Click method for that off screen button, white doesn't click on the button. How can I make this work? I hope the explanation is clear.
