Looking for synchronous map view source code

[LeiZhou]

I am looking for a source code as below or similar to that.

That can an synchronous view for two or three map panels.  ESRI had one online before, but I can not find it. Does any one still have the code or know where I can find it?  The question can be also which API function I should use to create this function? Thanks a lot!

Lei,

   I don't have that source code but this can easily be done using event listeners. Just listen for the maps extentChange event and the panEnd event on each map and update the extent of the other maps to be the extent of the map that dispatched the event.

Thanks! I will try that...
