I have a StatRow in a FixedFooter that calculates a sum of a column. When a value changes in the underlying data collection, how can I force the StatRow to refresh? I would expect that changing the value through the grid would have caused the refresh - but it doesn't. At this point, I have coded the collection to send the change event, but I can't figure out how to make the StatRow redraw after changing a row in the grid. Any help?

The StatRow should update automatically if the values that are being changed are in its StatContext. Do you have any errors in the output window? How is your StatRow defined?

Here it is... If I just edit a value in the grid and press Enter to EndEdit the row, then I would expect that the StatRow would update. It doesn't do anything... If I rebind the grid to another data source and back again then it re-calculates as expected.

Hi Adam,

I was unable to reproduce the behavior you are reporting. Would it be possible for you to send a repro application to my attention at support@xceedsoft.com?
