本指南演示了在运行时刻如何对报表数据排序。

要通过代码对报表数据排序，则使用下面的构造函数创建一个 GroupField 对象，并把它添加到 DetailBand.SortFields 集合中。

C#	复制代码
using System; using System.Drawing; using DevExpress.XtraReports.UI; // ... private void XtraReport1_BeforePrint(object sender, Printing.PrintEventArgs e) { Detail.SortFields.Add(new GroupField("ProductName", XRColumnSortOrder.Ascending)); }

复制代码

using System;
using System.Drawing;
using DevExpress.XtraReports.UI;
// ...

private void XtraReport1_BeforePrint(object sender, Printing.PrintEventArgs e) {
    Detail.SortFields.Add(new GroupField("ProductName", XRColumnSortOrder.Ascending));
}

Visual Basic	复制代码
Imports System Imports System.Drawing Imports DevExpress.XtraReports.UI ' ... Private Sub XtraReport1_BeforePrint(ByVal sender As Object, _ ByVal e As PrintEventArgs) Handles MyBase.BeforePrint Detail.SortFields.Add(New GroupField("ProductName", XRColumnSortOrder.Ascending)) End Sub

Visual Basic

复制代码

Imports System
Imports System.Drawing
Imports DevExpress.XtraReports.UI
' ...

Private Sub XtraReport1_BeforePrint(ByVal sender As Object, _ 
ByVal e As PrintEventArgs) Handles MyBase.BeforePrint
    Detail.SortFields.Add(New GroupField("ProductName", XRColumnSortOrder.Ascending))
End Sub
