Display radius of draw circle while dragging

Discussion created by meyvn77 on Feb 21, 2014
I am using the draw tools to select on the map and return the selected results from some feature layers.
I would like to add some functionality to my circle select tool. I would like to have a display of the distance from the center point to where they are dragging it. I have seen an example function to calculate it and connect to the events but am not sure how to display it on the circle being drawn...

If anyone has done this and can help it would be greatly appreciated.
