I have successfully created a data extract widget. It works great.
I would now like to be able to set a limit say of 5000sqm or something.
I have seen other sites do this. They have a message pop up saying:
you have exceeded the size limitation, reduce your area of interest.
Looking for some sugestions on how to achieve this.
here is some examples of sites that do what I would like to achieve
We are an ESRI site, using Flex 3.6 viewer and Flex SDK 4.6. Hope that makes sense.
