使用WPF的ReportDataSource名称和值 [英] ReportDataSource name and value using WPF

问题描述

我在WPF窗口中尝试使用WindowsFormsHost打开RDLC报告时遇到以下问题.打开报告时，将出现一个没有数据的报告标题.该查询没有参数，并且我已经多次预览了数据集中的数据.

我已经看到了很多尝试来解释ReportDataSource.Name和ReportDataSource.value的含义的尝试，但是对于我来说，尚不清楚它们分别是什么意思.除了下面列出的内容以外，我什么都无法执行.

谢谢-

I have the following in a WPF window trying to open an RDLC report using a WindowsFormsHost. When the report opens there is a report header with no data. The query has no parameters and I have previewed the data in the data set many times.

I have seen many attempts to explain the meanings of ReportDataSource.Name and ReportDataSource.value but it is not yet clear to me what each is supposed to mean. I have not been able to implement anything but that which is listed below.

Thanks -

string reportPath = "C:\\Dev\\2010\\2010_BoxingAdmin\\BoxingAdmin\\BoxingAdmin\\Report1.rdlc";
            string ds = "DEVELOPMENT;Initial Catalog=Boxing;Integrated Security=True";
            ReportDataSource rds = new ReportDataSource("DataSet1", ds);
            ReportViewer reportViewer = new ReportViewer();
            reportViewer.ProcessingMode = ProcessingMode.Local;
            reportViewer.LocalReport.ReportPath = reportPath;
            reportViewer.LocalReport.DataSources.Add(rds);   
            windowsFormsHost1.Child = reportViewer;
            reportViewer.RefreshReport();

推荐答案

我也犯了同样的错误，就是您在这里所做的.

这里的第二个参数只是您的连接字符串.它实际上不是数据源.但是我不知道第一个参数.现在我仍然找到那个.

I also do the same mistake, what you made here.

The second parameter here is just your connection string. It''s not actually a data source. But I don''t know about first parameter. Now i am still finding that.
