GridControl Cell Refresh

[Administrator]

Hi All,
I am using Refresh() to refresh Syncfusion.Windows.Forms.Grid.GridControl data if any real-time update. I think that is not a good way to refresh the whole grid data once data is arrived. Kindly to know if any way only to refresh the cell text instead of whole Grid?
Thanks.

Hi Derek,

Thanks for the interest in Syncfusion Grid.

You can refresh a cell rather than the whole grid. You can get the CurrentCell of the grid and can refresh the Grid. Please refer the following code snippet that shows how we can refresh the CurrentCell of the Grid on mouse click.

        private void gridControl1_MouseUp(object sender, MouseEventArgs e)
        {
            GridCurrentCell currentCell = this.gridControl1.CurrentCell;
            this.gridControl1[currentCell.RowIndex,currentCell.ColIndex].Text = "Refresh";
            currentCell.Refresh();
        }

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

Please let me know if you have any questions.

Hi Asem,
Thanks for the information. However, the cell is only refreshed when you click on it. I would like to know if any way to refresh the cell if my grid have real time update.

Hi Derek,

Thank you for your interest in Syncfusion products.

You need to call RefreshRange method to refresh a particular cell in the place where you perform realtime update. Here is the sample code.

 this.gridControl1.RefreshRange(GridRangeInfo.Cell(1, 1));

Please refer the below browser sample which deals with real time update and refresh grid.
