Remarks

The CustomDrawCell event is raised before a data cell is painted. The event parameter provides all the information necessary to paint a cell. Set the PivotCustomDrawCellEventArgs.Handled property to true to prohibit default cell painting.

NOTE

Custom drawing of any kind is ignored when printing PivotGridControl. To change the appearance of cells when the Pivot Grid Control is displayed onscreen and in the print output, handle the PivotGridControl.CustomAppearance event.

NOTE

To access event data while an asynchronous operation is being performed, use a thread-safe event parameter returned by the PivotCustomDrawCellEventArgs.ThreadSafeArgs property. To learn more, see Asynchronous Mode.

IMPORTANT

Do not change cell values, modify the control’s layout, or change the control’s object model in the events used for custom control painting. Actions that update the layout can cause the control to malfunction.

Example

The following sample code handles the PivotGridControl.CustomDrawCell event to custom paint Grand Total cells. The image below shows the result.

PivotGrid_CustomDrawCell

using DevExpress.XtraPivotGrid;
using System.Drawing;

private void PivotGridControl1_CustomDrawCell(object sender, PivotCustomDrawCellEventArgs e)
{
  if (e.ColumnValueType == PivotGridValueType.GrandTotal ||
    e.RowValueType == PivotGridValueType.GrandTotal)
  {
    Rectangle r;
    Brush brushFillTotals;
    brushFillTotals = e.GraphicsCache.GetSolidBrush(ColorTranslator.FromHtml("#0099cc"));
    r = e.Bounds;
    e.GraphicsCache.FillRectangle(brushFillTotals, e.Bounds);
    r.Inflate(-4, -4);
    e.GraphicsCache.DrawString(e.DisplayText, e.Appearance.Font,
    Brushes.White, r, e.Appearance.GetStringFormat());
    e.Handled = true;
  }
}
