Export C# reportviewer control programmatically
提问by
Does anyone know if you can programmatically save a report shown in a reportviewer control in C#?
有谁知道您是否可以以编程方式保存在 C# 中的报表查看器控件中显示的报表？
When a report is shown there are "Export to..." buttons and I would like to automate the saving to PDF function.
当显示报告时，有“导出到...”按钮，我想自动保存到 PDF 功能。

You can do this with ReportViewer Control(with LocalReport.Render Method), check "Email a report" example at the http://www.gotreportviewer.com/
您可以使用ReportViewer 控件（使用LocalReport.Render Method）执行此操作，请检查http://www.gotreportviewer.com/ 上的“通过电子邮件发送报告”示例

SaveFileDialog saveFileDialog1 = new SaveFileDialog();
saveFileDialog1.Filter = "*PDF files (*.pdf)|*.pdf";

if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
FileStream newFile = new FileStream(saveFileDialog1.FileName, FileMode.Create);
newFile.Write(byteViewer, 0, byteViewer.Length);
newFile.Close();
}

You can't export to an event as far as reportviewerin web forms are concerned.
就reportviewer网络表单而言，您无法导出到事件。
