SL复合表头报表实现（包含导出和打印）

      复合表头报表除了使用报表工具来实现外，在Silverlight里面还可以使用DataGrid和RadGridView来实现，这里介绍一下RadGridView如何实现复合表头的报表。

首先来看代码实例：

   1、XAML代码

</Grid>

PS：为了兼容分辨率，这里采用了DataGrid的百分比布局。

       如果重复的引用Telerik的命名空间则会引发错误。

      错误内容：
      错误 1 分析规则 Element ::= . EmptyElement | ( StartElement ElementBody ). 中的意外 PROPERTYELEMENT。 E:\Test\SLReportTest\SLReportTest\MainPage.xaml SLReportTest

      这里是“元素冲突导致的”，要把控件元素里的命名空间删除掉，因为空间内部属性设置冲突。

2、后台代码实现打印和导出

      

private void bt_Confirm_Click(object sender, RoutedEventArgs e)
{

}

/// <summary>
/// 打印
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void bt_Print_Click(object sender, RoutedEventArgs e)
{
PrintDocument prtDoc = new PrintDocument();
prtDoc.PrintPage += new EventHandler<PrintPageEventArgs>(prtDoc_PrintPage);
string title = txtBTitle.Text;
prtDoc.Print(title); // " Printing Test " 是文档名 在打印机的任务列表里可以看到
}

void prtDoc_PrintPage(object sender, PrintPageEventArgs e)
{
e.PageVisual = gdCircuitReport; //打印所有内容
}

private void bt_Excel_Click(object sender, RoutedEventArgs e)
{
string extensioin = "xls";
ExportFormat format = ExportFormat.Html;
SaveFileDialog dialog = new SaveFileDialog();
dialog.DefaultExt = extensioin;
dialog.Filter = String.Format("{1} files (*.{0})|*.{0}|All files (*.*)|*.*", extensioin, "Excel");
dialog.DefaultFileName = txtBTitle.Text;
dialog.FilterIndex = 1;

if (dialog.ShowDialog() == true)
{
try
{
using (Stream str = dialog.OpenFile())
{
GridViewExportOptions exportextension = new GridViewExportOptions();
exportextension.Format = format;
exportextension.Encoding = System.Text.Encoding.GetEncoding("utf-8");//放置乱码的出现
exportextension.ShowColumnFooters = true;
exportextension.ShowColumnHeaders = true;
exportextension.ShowGroupFooters = true;

this.rgv_list.Export(str, exportextension);

}
}
catch (Exception)
{
}
}

//rgv_list.ToCsv();//Csv文件
//string extension = "csv";
//SaveFileDialog dialog = new SaveFileDialog()
//{
// DefaultExt = extension,
// Filter = String.Format("{1} files (*.{0})|*.{0}|All files (*.*)|*.*", extension, "CSV"),
// FilterIndex = 1
//};
//if (dialog.ShowDialog() == true)
//{
// using (Stream stream = dialog.OpenFile())
// {
// rgv_list.Export(stream,
// new GridViewExportOptions()
// {
// Format = ExportFormat.Csv,
// ShowColumnHeaders = true,
// ShowColumnFooters = true,
// ShowGroupFooters = false,
// });
// }
//}

}

      前台代码定义了报表的绑定格式，这里的后台代码实现了报表的打印和导出。
