The value of a click cell with ultragrid

Hello,

I'm using ultragrid to show my data. I need an event that allows me to get this cell value... I tryed with AfterCellActivate and clickcell and:

grid.ActiveRow.Cells["Name"].Value.ToString();

grid.ActiveCell.Value.ToString();

grid.Selected.Cells.ToString();

But none of them worked

How can I get a celkl value when a click to this cell is cliked?

Thanks
