Remarks

The CustomExportCell event is raised for each cell when the ASPxPivotGrid is exported. You can handle this event to change the cell’s appearance and contents in a printed document.

Note

Data field properties cannot be changed in the CustomExportCell event handler.

Note

The CustomExportCell and ASPxPivotGridExporter.CustomExportFieldValue events are not in effect during the export in Data-Aware mode. To customize cells in Data-Aware export mode, use the PivotXlsExportOptions.CustomizeCell and PivotXlsxExportOptions.CustomizeCell events.

Example

This example shows how to display custom text within cells when the pivot grid’s data is exported to a file in XLS format. To do this, the ASPxPivotGridExporter.CustomExportCell event is handled.

The image below shows the result:

C#

using System;
using System.Drawing;
using DevExpress.XtraPivotGrid.Web;
using DevExpress.XtraPrinting;

public partial class _Default : System.Web.UI.Page 
{
    static double maxPrice = 99;
    protected void ASPxPivotGridExporter1_CustomExportCell(
                          object sender,
                          WebCustomExportCellEventArgs e) {
        if (e.DataField.FieldName == "UnitPrice" &&
                Convert.ToDouble(e.Value) > 0 &&
                Convert.ToDouble(e.Value) < maxPrice) {
            // Specifies the cell's display text.
            ((TextBrick)e.Brick).Text = string.Format(
                     "Custom text: {0}",
                     ((TextBrick)e.Brick).Text);
            // Specifies the appearance settings used to paint the cell in a document.
            e.Appearance.BackColor = Color.Green;
            e.Appearance.ForeColor = Color.White;
        }
    }
    protected void ASPxButton1_Click(object sender, EventArgs e) {
        ASPxPivotGridExporter1.ExportToXls(@"C:\pivotdata.xls", TextExportMode.Text);
    }
}
