废话少说开始正事

在继续本示例之前，要把所有必需的程序集添加到项目的引用列表中，并且把一个按钮拖放到窗体上。然后，以下列方式接管此按钮的 Click 事件。

using System;
using System.Data;
using System.Data.OleDb;
using System.Windows.Forms;
using DevExpress.XtraPivotGrid;
using DevExpress.XtraReports.UI;
using DevExpress.XtraReports.UI.PivotGrid;
// ...

namespace docXRPivotGrid {
public partial class Form1 : Form {
public Form1() {
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e) {
// Create a cross-tab report.
XtraReport report = CreateReport();

// Show its Print Preview.
report.ShowPreview();
}

private XtraReport CreateReport() {
// Create a blank report.
XtraReport rep = new XtraReport();

// Create a detail band and add it to the report.
DetailBand detail = new DetailBand();
rep.Bands.Add(detail);

// Create a pivot grid and add it to the Detail band.
XRPivotGrid pivotGrid = new XRPivotGrid();
detail.Controls.Add(pivotGrid);

// Create a data connection.
OleDbConnection connection = new
OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=..\\..\\nwind.mdb");

// Create a data adapter.
OleDbDataAdapter adapter = new
OleDbDataAdapter("SELECT CategoryName, ProductName, Country, [Sales Person], Quantity, [Extended Price] FROM SalesPerson",
connection);

// Creata a dataset and fill it.
DataSet dataSet1 = new DataSet();
adapter.Fill(dataSet1, "SalesPerson");

// Bind the pivot grid to data.
pivotGrid.DataSource = dataSet1;
pivotGrid.DataMember = "SalesPerson";

// Generate pivot grid's fields.
XRPivotGridField fieldCategoryName = new XRPivotGridField("CategoryName",
PivotArea.RowArea);
XRPivotGridField fieldProductName = new XRPivotGridField("ProductName", PivotArea.RowArea);
XRPivotGridField fieldCountry = new XRPivotGridField("Country", PivotArea.ColumnArea);
XRPivotGridField fieldSalesPerson = new XRPivotGridField("Sales Person",
PivotArea.ColumnArea);
XRPivotGridField fieldQuantity = new XRPivotGridField("Quantity", PivotArea.DataArea);
XRPivotGridField fieldExtendedPrice = new XRPivotGridField("Extended Price",
PivotArea.DataArea);

// Add these fields to the pivot grid.
pivotGrid.Fields.AddRange(new PivotGridField[] {fieldCategoryName, fieldProductName,
fieldCountry,
fieldSalesPerson, fieldQuantity, fieldExtendedPrice});

return rep;
}
}
}
