    {
        InitializeComponent();

        sfDataGrid1.CurrentCellActivated += SfDataGrid1_CurrentCellActivated; 
    } 

    private void SfDataGrid1_CurrentCellActivated(object sender, Syncfusion.WinForms.DataGrid.Events.CurrentCellActivatedEventArgs e)
    {
        sfDataGrid1.TableControl.Invalidate(sfDataGrid1.TableControl.GetRowRectangle(sfDataGrid1.TableControl.GetHeaderIndex(), false));
    }
    
}
