XtraReports > 示例 > 如何： 显示打印预览窗体

这个示例展示了如何在标准的 打印预览 窗体中显示报表文档，其中使用了 ReportPrintTool 类并调用了 PrintTool.ShowPreview 或 PrintTool.ShowPreviewDialog 方法。

要使本示例能正确工作，则派生于 XtraReport 类的 XtraReport1 子类应该存在于示例应用程序中。 (译者注： 不要忘了把 DevExpress.XtraPrinting.vxx.x.dll 程序集添加到项目的引用，其中 vxx.x 表示具体的版本号，例如 DevExpress.XtraPrinting.v10.2.dll)

// ...

private void Form1_Load(object sender, EventArgs e) {
    XtraReport1 report = new XtraReport1();
    ReportPrintTool printTool = new ReportPrintTool(report);

    // Invoke the Print Preview form modally, 
    // and load the report document into it.
    printTool.ShowPreviewDialog();

    // Invoke the Print Preview form
    // with the specified look and feel setting.
    printTool.ShowPreview(UserLookAndFeel.Default);
}
