GGC Remember old cell value

[Administrator]

Hi

Is their a built in function to know or even remember the value of a cell in the grid?
I would also need to know if there is something like row state filter or a way to know if a cell value has changed

Thanks

Hi Francois,

Thanks for the interest in Syncfusion products.

You can remember the value of the cell in a grid when the cell is validating. You can use CurrentCellValidated event to know if a cell value has changed. Please refer the following code snippet that shows how we can achieve this behavior.

        private void gridControl1_CurrentCellValidated(object sender, EventArgs e)
        {
            GridCurrentCell cc = this.gridControl1.CurrentCell;
            string newValue = cc.Renderer.ControlText;
            string oldValue = this.gridControl1[cc.RowIndex, cc.ColIndex].Text;
            if (oldValue != newValue)
            {
                if(MessageBox.Show("[Value Changed to]: " +newValue + "     [OldVaue ]: "+ oldValue+" \n\nWant to Save ?"  ,"Validating Cells" , MessageBoxButtons.YesNo,MessageBoxIcon.Warning) ==DialogResult.Yes)
                                {
                    this.gridControl1.EndUpdate();
                }
                else
                {
                    cc.RejectChanges();
                    this.gridControl1[cc.RowIndex, cc.ColIndex].Text = oldValue;
                    this.gridControl1.EndUpdate();
                }
            }
        }

Please refer the sample in the below link that illustrates the above.

Please let me know if this is not what you needed.
