Show() End Sub Private Sub frm Sample Receipt_Load(By Val sender As System. void Validate Row(object sender, Data Grid View Cell Cancel Event Args e) { Data Grid View tmp DGV = ((Data Grid View)sender); try catch (Index Out Of Range Exception ex) If i debug this code and step through it i can see that when i have finished editing the new record and hit enter the row validating event handler fires.

The user gets an error icon on the row, and cannot leave the cell.
