Silverlight4使用radgridview读取导出CSV文件

导出CSV

        private void btnInsert_Click(object sender,RoutedEventArgs e)
        {
            radGridView1.ToCsv();
            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())
                {
                    radGridView1.Export(stream,                     new GridViewExportOptions()
                     {
                         Format = ExportFormat.Csv,                         ShowColumnHeaders = true,                         ShowColumnFooters = true,                         ShowGroupFooters = false,                     });
                }
            }
        }
