  Want a blank report viewer

  Feb 21, 2012 07:59 PM|LINK

  The way my rdlc & report viewer is set up, the rdlc gets and displays all available records, by default.

  I would like it to default to an empty report.

  Having trouble getting this.

  Help pls?

  Hi

  You can use ReportViewer1.clear();

  to clean the Reprotviewer I　think.

  Hope it helpful.

  Just put report viewer in aspx without additional properties like in following code.

  <rsweb:ReportViewer ID="rptvwrReport" runat="server" Width="100%" Font-Names="Verdana" Font-Size="8pt" Height="659px">
                  
              </rsweb:ReportViewer>

  Attach your RDLC and parameters in code behind like below:

  rptvwrReport.LocalReport.ReportPath = "rptReport.rdlc";
          ReportDataSource rds = new ReportDataSource("DSRequest_usp_rpt_selRequests", DS.Tables[0]);
          ReportParameter p1 = new ReportParameter();
          ReportParameter p2 = new ReportParameter();
          p1 = new ReportParameter("pFromDate", Convert.ToString(txtFromDate.Text));
          p2 = new ReportParameter("pToDate", Convert.ToString(txtToDate.Text));
          rptvwrReport.LocalReport.DataSources.Clear();
          rptvwrReport.LocalReport.DataSources.Add(rds);
          this.rptvwrReport.LocalReport.SetParameters(new ReportParameter[] { p1, p2 });
          rptvwrReport.LocalReport.Refresh();

  If you feel it helps, Mark as answered so that it can help others to find solution.
