Hello All,

               I’m new to Mapguide. I am trying to get the ZoomToView to run
but am having issues. I can get it to work if I place my .aspx page in the
Task Pane of the map. But when I try to use it from an .aspx page from
outside of the task pane it doesn’t work. The map loads fine and my query
works fine, I get results but I can’t seem to get any javascript to run on
the map. I hard coded the coordinates for the ZoomToView in the code below.
The same code works fine when run from the Task Pane but again I’d like to
run it from outside the Task Pane. Thanks
