【Stimulsoft Reports Silverlight教程】在代码中使用报表变量

下载Stimulsoft Reports Silverlight最新版本

此示例显示如何使用报表变量并在代码中设置其值。有必要在报表中定义变量，然后可以使用变量名称通过代码设置值。首先，使用变量加载报表：

private void btDesign_Click(object sender, System.Windows.RoutedEventArgs e)
{
    var stream = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream("UsingReportVariables.Variables.mrt");
    stiReport1.Load(stream);
    stream.Close();
    stream.Dispose();
    stream = null;
    stiReport1.Design();
}

然后，在btPreview_Click事件中，为报表变量分配新值。您可以使用报表变量名称：

private void btPreview_Click(object sender, System.Windows.RoutedEventArgs e)
{
    viewer.Visibility = System.Windows.Visibility.Visible;
    viewer.Report = null;
 
    var stream = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream("UsingReportVariables.Variables.mrt");
    stiReport1.Load(stream);
    stream.Close();
    stream.Dispose();
    stream = null;
 
    //Set Variables
    stiReport1["Name"] = tbName.Text;
    stiReport1["Surname"] = tbSurname.Text;
    stiReport1["Email"] = tbEmail.Text;
    stiReport1["Address"] = tbAddress.Text;
    stiReport1["Sex"] = rbMale.IsChecked;
    stiReport1["BirthDay"] = dtBirthDay.DisplayDate;
 
    stiReport1.Render();
    viewer.Report = stiReport1;
}

下面的屏幕截图中，您可以看到示例代码的结果。
