Scale Change Event for Map Control

ErnieSalazar — Tue, 21 Aug 2012 13:42:59 GMT

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
