Selection Marker in Row Header

[Arif Eqbal]

Hi,
I am working on a gridGroupingControl, I have the Row Headers visible for the Grid. I want to show a marker or text '*' in the Row Header of the Row that is currently selected. To restrict the Users to select only certain rows, I handle the TableControlCellClick event and manually Select the Row. In the same event handler I would like to mark the Row as selected by showing a marker in the row header.

Thanks

Hi Arif,

Thank you for posting query to us.

It is possible to show the text in the Row Header of the currently selected rows by handling the events TableControlCellDrawn and TableModel.SelectionChanged of GridGroupingControl.
Here is the code snippets:

 void TableModel_SelectionChanged(object sender, GridSelectionChangedEventArgs e)
        {
            this.gridGroupingControl1.Refresh();
        }

        void gridGroupingControl1_TableControlCellDrawn(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlDrawCellEventArgs e)
        {
            GridRangeInfoList list = gridGroupingControl1.TableModel.Selections.Ranges;
            foreach (GridRangeInfo range in list)
            {
                if (e.Inner.RowIndex >= range.Top && e.Inner.RowIndex <= range.Bottom)
                {
                    if (e.Inner.ColIndex == 0)
                    {
                        e.Inner.Graphics.DrawString("*", new Font("Aerial", 10), Brushes.Red, e.Inner.Bounds.Location);
                        e.Inner.Cancel = true;
                    }
               
               }
            }
        }
