我是 asp.net 编程的新手，我想在单击按钮时在 reportviewer 中加载 rdlc 报告。问题是如果我在页面加载时调用 LoadReport 函数，报告会正确加载，但是当我在按钮单击时加载报告时会出现问题.它没有显示错误。我已经创建了DataSet1.xsd并将其附加到rdlc报告中，在另一个aspx页面中我填充了DataSet1.xsd并附加到ReportDataSource（）。它显示了数字列以及数据并且它被绑定报告没有错误，但每当我看到 aspx 页面时，它总是空白。请提供解决方案，因为它是我的优先任务。这是我的代码；
private void LoadReport()
{
GetData();
ReportViewer1.LocalReport.ReportPath = Server.MapPath("Reports/Report2.rdlc");
ReportViewer1.ProcessingMode = ProcessingMode.Local;
ReportDataSource rds = new ReportDataSource();
rds.Name = "DataSet1";
rds.Value = ds.DataTable1;
ReportViewer1.LocalReport.DataSources.Clear();
ReportViewer1.LocalReport.DataSources.Add(rds);
ReportViewer1.DataBind();
LocalizeReport(ReportViewer1.LocalReport);
ReportViewer1.LocalReport.Refresh();
ReportViewer1.Visible = true;
}
private void GetData()
{
DataSet1.DataTable1Row dr = ds.DataTable1.NewDataTable1Row();
dr[0] = "abc";
dr[1] = "49/Male";
dr[2] = "21656";
dr[3] = " ";
dr[4] = " ";
dr[5] = " ";
dr[6] = " ";
dr[7] = " ";
dr[8] = " ";
dr[9] = " ";
dr[10] = "abc";
dr[11] = "ccvc";
dr[12] = "abc";
dr[13] = " ";
dr[14] = " ";
dr[15] = "abc ";
dr[16] = " ";
ds.DataTable1.AcceptChanges();
ds.DataTable1.AddDataTable1Row(dr);
}
}
