i developing website using asp.net. use crystal report reporting tool. use code load report

          rpt.load(server.mappath("~\\reports\\a4\\grndetailreport-a4.rpt"));            rpt.setparametervalue("datefrom", dtimefrom);           rpt.setparametervalue("dateto", dtimeto);           rpt.setparametervalue("companyid",ddcompanynames.selectedvalue);           rpt.setparametervalue("locationid", ddlocations.selectedvalue);            crystalreportviewer1.toolpanelview = crystaldecisions.web.toolpanelviewtype.none;           crystalreportviewer1.reportsource = rpt;         crystalreportviewer1.databind();

so above code working issues. report loading. data not displaying. enter image description here

when press refresh button on page displaying. whats gone wrong there?

i called function @ bottom of above code.

crystalreportviewer1.refreshreport();

but still got problem.

please try solution:

  crystalreportviewer1.reportsource = rpt;   rpt.readrecords();   \\crystalreportviewer1.databind();
