Hi there,
Currently, I'm working on a grid, where use is allowed to change the value of the cell. I have an aggregation function for this column. Everything is fine as long as user doesn't change the value. The aggregate value doesn't seem to change upon user change cell value.
How should I do this, so the aggregated value will get updated upon user change one of the cells' value? By the way, I use a custom aggregate function this case.
