Gets the current value of the specified data source field.

Namespace: DevExpress.XtraReports.UI.CrossTab

Assembly: DevExpress.XtraReports.v24.1.dll

NuGet Package: DevExpress.Reporting.Core

Declaration

C#

public object GetCurrentFieldValue(
    string name
)

VB.NET

Public Function GetCurrentFieldValue(
    name As String
) As Object

Parameters

Name	Type	Description
name	String	The name of the data field to obtain the value from.

Returns

Type	Description
Object	The current value of the specified data source field. If the specified field was not found, this method returns null (Nothing in Visual Basic).

Remarks

Call the GetCurrentFieldValue method in the XRCrossTabCell.BeforePrint event handler to obtain the current value of the specified data source field. If you do not want to cast the returned object, use the GetCurrentColumnValue<T> method, which returns a strongly typed object.

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
