DBAdvWebGrd Column Enter

I'm looking for a way to trigger an event similar to a VCL DBGrid OnColumnEnter so that I can populate a stored procedure variable based upon which column in the AdvWebGrid is clicked.

I've tried all of the events of the Grid that seem likely (OnAsyncCellClick, OnCellClick, OnGetCellData, etc) but none of them fire when I run the app and click on a cell in the grid.




Please note that the On(Async)CellClick event is only triggered when MouseSelect is set to msRow or msSingleCell.
The OnGetCellData event is only triggered once, just before the initial rendering of the cell.
