I'm using the TrackOverlay to allow users to draw features on the map.
The user should only be able to draw one feature.
If the user clicks the draw point button and I change to TrackMode.Point how do I stop the user creating more than one point?
I guess this will involve creating a custom version of TrackOverlay and overriding the MouseUp andMouseDown events but this will be difficult because the user could be in TrackMode.Polygon and I wont know if the user is continuing with the first polygon or creating a second.
Any ideas?
Cheers
Steve
