I am using the Windows GUI

I have a list in a grid where only 1 record can be the standard. Using the handler i make sure other records who were standard are disabled when another record is made standard. The downside is the refresh of the data is not working right. I can understand it going wrong going from tick to tick, because i am never really leaving a row without going into edit mode of the next. But when i do click away from an updated record nothing happens, unless i click on that record. It only really refreshes all data when i press F5.
