此示例显示如何将 表加载到设计器以及如何使用保存 表事件。

private void btLoadReport_Click(object sender, System.Windows.RoutedEventArgs e){    if (cbReports.SelectedItem != null)    {        System.Reflection.Assembly a = System.Reflection.Assembly.GetExecutingAssembly();        var stream = a.GetManifestResourceStream(string.Format("DesignerSaveLoad.ReportFiles.{0}.mrt",            ((ComboBoxItem)cbReports.SelectedItem).Content.ToString()));        StiReport report = new StiReport();        report.Load(stream);        stream.Close();        stream.Dispose();        stream = null;        report.CalculationMode = StiCalculationMode.Interpretation;        report.RegBusinessObject("Data", "Data", new Data());        designer.Report = report;    }}

您可以在应用程序初始化时将事件侦听器添加到StiOptions.Engine.GlobalEvents：

public MainPage(){    ...    StiOptions.Engine.GlobalEvents.SavingReportInDesigner +=        new Stimulsoft.Report.Design.StiSavingObjectEventHandler(GlobalEvents_SavingReportInDesigner);}

指定 表保存时要执行的操作：

private void GlobalEvents_SavingReportInDesigner(object sender, Stimulsoft.Report.Design.StiSavingObjectEventArgs e){    if (designer.Report == null) return;    e.Processed = true;    messageBox = new MessageBoxWindow();    messageBox.Closed += delegate    {        if (messageBox.Result == MessageBoxResult.Yes)        {            SaveFileDialog saveDialog = new SaveFileDialog();            saveDialog.Filter = "Report Files (*.mrt) | *.mrt";            if (saveDialog.ShowDialog() == true)            {                var stream = saveDialog.OpenFile();                StiXmlReportSLService saveService = new StiXmlReportSLService();                saveService.Save(designer.Report, stream);                stream.Flush();                stream.Close();                stream.Dispose();                stream = null;            }        }        messageBox = null;    };    messageBox.Show();}

下面的屏幕截图中，您可以看到示例代码的结果。
