我认为没有必要提及aspx中的所有数据集信息以及后面的代码。您刚刚在aspx中输入了所有必需的代码。在其中排除这一行。

 <ServerReport ReportServerUrl="" />

没必要。您已在标记中指定了SelectMethod="GetData"，但我无法在后端看到任何返回与Dataset1匹配的数据项的GetData方法。因此，如果删除这些行，它将起作用

ReportViewer1.ProcessingMode = ProcessingMode.Local;
ReportViewer1.Reset();
ReportDataSource rds = new ReportDataSource("DataSet1", dt);
//ReportViewer1.LocalReport.ReportPath = Server.MapPath(@"CIB_CTL\\ReportProg.rdlc"); //"CIB_CTL\\ReportProg.rdlc";

ReportViewer1.LocalReport.ReportPath = "ReportProg.rdlc";  //"CIB_CTL\\ReportProg.rdlc";//Server.MapPath(@"ReportProg.rdlc");

ReportViewer1.LocalReport.DataSources.Clear();
ReportViewer1.LocalReport.DataSources.Add(rds);
ReportViewer1.LocalReport.Refresh();

并正确定义GetData。
