then set the ReportViewer1.LocalReport.ReportPath= property from the codebehind.then error desapier and working properly.my headache was how to set this property without doing any coding ?

回答1:

replace this line in your report view

<LocalReport ReportEmbeddedResource="report.Report1.rdlc">

to this line

 <LocalReport Reportpath="Report1.rdlc">

回答2:

If by 'without doing any coding' you mean without using the code-behind file, then you can set the ReportPath property inside the ReportViewer control itself like so:

<rsweb:ReportViewer id="report" runat="server">
    <LocalReport ReportPath="Your report path here"></LocalReport>
</rsweb:ReportViewer>
