Create a point using a TOC template C#

AnthonyStevens — Sun, 31 Mar 2013 22:10:57 GMT
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.
