I assume there is a toggle somewhere that will programatically turn on the RowEditTemplate version of a band and then turn off RowEditTemplate.
I assume there is a toggle to Enable / Disable use of the templates.
Figured it out - simply reset the RowEditTemplate for a band works....
FMECAGrid.DisplayLayout.Bands[FUNCTIONAL_REQUIREMENT].RowEditTemplate =
null;
this.FuncReqTemplate;
