Solution 1

sorry i cannot copy and paste code, but i have done this before, its very easy as far as i remember.

1.) Initialize ReportViewer
2.) Set the LocalReport-Path
3.) Use the Export to save it to disk

Code should be something along those lines:

C#

ReportViewer rv = new ReportViewer();
rv.LocalReport.ReportPath = @"resources\test.rdlc";
rv.RefreshReport();
File.WriteAllBytes(@"c:\my.pdf", rv.LocalReport.Render("PDF"));

its show "An error occurred during local report processing". at 3rd line in your code.
Basically its a rdlc which has subreport and i am having dataset in that rdlc

Third Line? I would have expected second line, as i said, the lines are to be understood as pseudo-code;-)
try rv.Update() or rv.Show() in between the lines to force the data to be loaded (i editted my solution).
If this doesnt work, look up the Render-Method of the LocalReport:

I am sorry, i cant help you any further within the next probably 10 hours, and until then i will have forgotten you, so better not expect further help.

hi
Please try this

XML

<rsweb:ReportViewer ID="Report1" runat="server" Font-Names="Verdana" Font-Size="8pt"
    Height="515px" Width="100%" ShowExportControls="true" SizeToReportContent="False" >
    <LocalReport ReportPath="Rdlc\reports1.rdlc" EnableHyperlinks="True">
        <DataSources>
            <rsweb:ReportDataSource DataSourceId="ObjectDataSource1" Name="reports1_reports1" />
        </DataSources>
    </LocalReport>
</rsweb:ReportViewer>
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server" SelectMethod="GetData"
    TypeName="ReportTableAdapters."></asp:ObjectDataSource>

//Code behind

C#

ReportDataSource datasource = new
                   ReportDataSource("reports1_reports1",
             dtViewInfo);



              Report1.LocalReport.DataSources.Clear();
              Report1.LocalReport.DataSources.Add(datasource);
              Report1.LocalReport.Refresh();

              Report1.Visible = true;
