Hi,

I have a question, I use SketchViewModel to draw the shape on map, I want to keep the shape located in center (not moving) when the map is moving by pan or drag; how can I implement it?  

Thanks in advance.

Get the extent of the map.
Pick a corner of the map and store it in a variable (startingPoint).

Listen for the map to move. When it does, get the new extent.
Check the change from startingPoint to the new extent. (Ex. +3 degrees lat, -2 long)

Get the geometry of the shape you drew.
Loop through each point on the shape and adjust the coordinates by the same amount the startingPoint shifted.
