How to troubleshoot Datagrid Behavior errors

[Bob Sneidar]

Hi all. 

I have one stack that will throw errors in the column behavior. I set the global gRevDevelopment to true and set a try catch with a breakpoint in the two places where it seems to fail, but the script is not breaking. Instead it ignores the breakpoint and continues to run. 

How do I troubleshoot datagrid behavior issues?
