I want to display the radius of drawing circle when user adds this figure on the map.
- User clicks on the icon.
Then user begins drawing circle (I process the MouseDown event)
IGeometry geom = Map.TrackCircle();
When user clicks on the map, I draw this circle on the map (I get radius from TrackCircle and center from mouse coordinates).
I want to display radius on the map or in the bottom tooltip (like ArcMap) on the step 2 (TrackCircle).
I think I must process the event OnAfterDraw of the MapControl, but I do not know how (how can I know that user drawing circle and the radius of this circle?).
