Cloning Map events

[ESRIESRI1]

Hi -
I have a page with two map controls with different data source, I am trying to clone the events but unable to do so. When I zoom in or zoom out or pan in map1 and map2 should be automatically repeat the same events . I am developing a tutorial to measure the performance of a map with two data sources. Please help me.

I suggest you look at this sample: http://resources.arcgis.com/en/help/silverlight-api/samples/start.htm#SwipeMap
There are 2 maps with extents which are synchronized.
