emergent help needed on GCC

Question

Syncfusion 4.4.I use dataTable as the dataSource of a GCC. The feature I want is when user write data into the GCC and hit key Enter, I want the data in the current cell to be validated in my defined way and pop up error if there is any. But I haven't found the right event to fire,I have tried TableControlCurrentCellKeyDown, TableControlCurrentCellKeyPress, but neither accepts key Enter.

Hi Jane,Thank you for your interest in Syncfusion products.You can validate the cell using CurrentCellValidating event.You can also handle CurrentCellKeyDown and CurrentCellKeyPress events , validate the current cell and display the error message.The following code snippet validates a double value and changes the message.You can also use ErroProvider to display the error message.[C#]private void gridControl1_CurrentCellKeyDown(object sender, KeyEventArgs e)        {             if (e.KeyCode == Keys.Enter)            {                GridCurrentCell cc = this.gridControl1.CurrentCell;                String s = cc.Renderer.ControlText;                try                {                    Double d = double.Parse(s);                }                catch                {                    cc.ErrorMessage = "My error message";                }            }        }Please let me know if this meets your requirement.Regards,Jaya

Jaya,This partially helps.I tried CurrentCellValidating, CurrentCellKeyPress and CurrentCellKeyDown, all don't pop error even there is error when Enter is hit. Eventually I used CurrentCellValidating, and redirect the focus to the current cell, then it works fine.Thanks a lot!Jane>Hi Jane,Thank you for your interest in Syncfusion products.You can validate the cell using CurrentCellValidating event.You can also handle CurrentCellKeyDown and CurrentCellKeyPress events , validate the current cell and display the error message.The following code snippet validates a double value and changes the message.You can also use ErroProvider to display the error message.[C#]private void gridControl1_CurrentCellKeyDown(object sender, KeyEventArgs e)        {             if (e.KeyCode == Keys.Enter)            {                GridCurrentCell cc = this.gridControl1.CurrentCell;                String s = cc.Renderer.ControlText;                try                {                    Double d = double.Parse(s);                }                catch                {                    cc.ErrorMessage = "My error message";                }            }        }Please let me know if this meets your requirement.Regards,Jaya
