When using the draw toolbar to add polygons and lines to a GraphicsLayer, I have some code that adds a measurements graphic (using a TextSymbol) on top of it.
My issue is that when using the edit toolbar to move those polygons around, obviously the measurement graphic I added does not follow. I want it to follow.
When using the edit toolbar to move a graphic, the graphic-move event handlers returns the linear transformation (dy/dy) in screen units.
I was thinking of using this delta to move the measurement graphic by the same amount. However the graphics point is in map units, so I can't offset it using this delta.
Is there any way I could convert this screen units delta to map units delta to move this other graphic by the same amount ?
