Hi All.

I.m a new developer (i´m student), I´m trying to generate a reportviewer passing parameters, I followed some tutorials of this site however does not work, always appears the following error.

"None provided any instance of data source for the origin of 'r_instructores' data."
in spanish appears "No se ha proporcionado ninguna instancia de origen de datos para el origen de datos 'r_instructores'.", this is my code.

ASPX Page

<rsweb:ReportViewer ID="ReportViewer1" runat="server" Font-Names="Verdana" Font-Size="8pt" WaitMessageFont-Names="Verdana" WaitMessageFont-Size="14pt">
       <LocalReport ReportPath="reportes\Report1.rdlc">
           <DataSources>
        <rsweb:ReportDataSource DataSourceId="ObjectDataSource1" Name="ARTES_OFICIOSDataSet" />
     </DataSources>
       </LocalReport>
   </rsweb:ReportViewer>
