我如何编程设置为ASP.NET ReportViewer控件的数据源？

How do I programmatically set the data source for the ASP.NET ReportViewer control?

我有一个VS 2008 ReportViewer控件，想了几种不同的报告之间切换。

I have a VS 2008 ReportViewer control and want to switch between a couple of different reports.

我可以通过设置报表源并刷新控制开关的报道，但我看不到的地方设置数据源。

I can switch reports by setting the report source and refreshing the control, but I can't see where to set the data source.

每个报告都有其自己的数据源，如果我配置它们最初在控制建它是好的，但我需要在它们之间进行切换。

Each report has its own data source, and if I configure them initially when the control is built it is fine, but I need to switch between them.

推荐答案

我认为问题是关于ReportViewer控件。

I assume the question is about ReportViewer control.

reportViewer.LocalReport.DataSources.Clear();
reportViewer.LocalReport.DataSources.Add(new ReportDataSource("dsname", source));

DSNAME是数据源的名称，你可以找到它.rdlc文件。 源是您要在报告中显示的数据变量。

"dsname" is the name of the data source, you can find it .rdlc file. source is the variable with data you want to show in the report.
