Create a point using a TOC template C#

Discussion created by srevihs_eulb on Mar 31, 2013
I cobbled together some C# code from a couple of developer samples to make a tool that will create a new point leveraging a point template selected in the TOC.  The tool works (creating a new point and storing it in the template layer), but the new point isn't visible until I zoom in/zoom out or hit the refresh button.  The point also isn't selected after it is created.  I've tried refresh and partial refresh from IActiveView, but that didn't work or I didn't do it right.  Any help would be greatly appreciated.
