Scale Change Event for Map Control

[ErnieSalazar]

Hi Everyone.

I want to be able to know when the scale of my main Map control changes.  I figured there would be an event already built into it but it appears there is not.  Then I thought I could just create my own class with inheritance from the Map control but it is sealed :/.

Am I missing something obvious?

Thanks
Ernie

You might use the Map.ExtentChanged event.

Thanks Dominque.  That got me to it.  I already had the ExtentChanged implemented but didnt realize that both envelopes were in the args.  That works if I calculate the difference in the envelopes.

Thanks
