I have an ADG and a slider. The grid is populated using a RO to ArrayCollection. I load up the ADG and use the slider to manipulate the data that happens to be a date (months) I want to total whats happening each month. my data currently has 8 records for each item. Thats one for each month (Jan-Aug) When I move the sliders like to one month just that record shows. What I really want it for there to be just one record thats total changes as you move the slider. "Dynamicaly Summing" the record sets. Is this even possible? If so How?
