Use a PageLayoutControl as an overview window

PurposeThis application contains two PageLayoutControls. The Browse dialog box allows users to search and select map documents that are validated and loaded into the main PageLayoutControl, thus triggering the OnPageLayoutReplaced event. The OnPageLayoutReplaced event determines the MxPath property of the main PageLayoutControl and uses it to load the same document into the second PageLayoutControl with the LoadMxFile method.

The OnExtentUpdated event is triggered when a user zooms in on the main PageLayoutControl. The event uses the AddElement method to add an element displaying the visible extent of the main PageLayoutControl on the second PageLayoutControl. Any previous elements on the second PageLayoutControl are found using the FindElementByName method and are deleted from the GraphicsContainer. The Refresh method is used to refresh the graphics to reflect the changes.
