I'm currently working with grids for EstimateLines. I'm having trouble setting the value of the IsMarkupPercent field. During the text change for the item field I set the value as IsMarkupPercent = Yes. However, when I make a call to return the value it shows up null, or empty. Later after a Lose Focus on the Quantity field I set the value again with "Yes", made a call and it shows up as IsMarkupPercent = Yes. However, when I check the value again after tabbing into the next field, the value shows IsMarkupPercent = false. Even though it returned a value of Yes, the IsMarkupPercent was never actually set. It just responded with what I recently typed.
It seems I've tried everything to force IsMarkupPercent to be Yes or true. Am I missing something? Is there some kind of trick to programatically setting Yes/No fields?
