The code is failing at the last line with a null reference exception. Funny thing is that the field "TitleName" is indeed a field in the datasource. This code had previously work.
When I set a break point above this line, I see that the VisibleColumns count is 1, which is one, but when I attempt to set the appearance, I am getting this error.
I initially had my ggc on a windows tab control. When I replace the windows tab control with the syncfusion control, this is when this strange error started occuring. I had my grouping on a syncfusion tab. I had four tabs and the ggc was on one of the tabs.
When I remove the syncfusion tab, the error went away. strange...

Hi James,
After setting the new data source try calling gridGroupingControl1.TableDescriptor.ResetColumns() to see if that helps.
