Example

This example demonstrates how to handle a Cross Tab cell’s BeforePrint event and customize the cell’s appearance based on its current value and row index.

C#

using System.Drawing;
using DevExpress.XtraReports.UI.CrossTab;
// ...
private void xrCrossTabCell3_BeforePrint(object sender, CrossTabCellPrintEventArgs e) {
    // Obtain the current cell.
    XRCrossTabCell cell = (XRCrossTabCell)sender;

    // Change the cell's foreground color if its value exceeds 3000.
    decimal value = cell.GetCurrentFieldValue<decimal>("Extended Price");
    if (value > 3000)
        cell.ForeColor = Color.Red;
    else cell.ForeColor = Color.Black;

    // Apply different background colors to odd and even rows.
    if (e.GroupRowIndex % 2 == 0)
        cell.BackColor = Color.LightCyan;
    else cell.BackColor = Color.White;
}

VB.NET

Imports System.Drawing
Imports DevExpress.XtraReports.UI.CrossTab
' ...
Private Sub xrCrossTabCell3_BeforePrint(ByVal sender As Object, ByVal e As CrossTabCellPrintEventArgs)
    ' Obtain the current cell.
    Dim cell As XRCrossTabCell = DirectCast(sender, XRCrossTabCell)

    ' Change the cell's foreground color if its value exceeds 3000.
    Dim value As Decimal = cell.GetCurrentFieldValue(Of Decimal)("Extended Price")
    If value > 3000 Then
        cell.ForeColor = Color.Red
    Else
        cell.ForeColor = Color.Black
    End If

    ' Apply different background colors to odd and even rows.
    If e.GroupRowIndex Mod 2 = 0 Then
        cell.BackColor = Color.LightCyan
    Else
        cell.BackColor = Color.White
    End If
End Sub
