I got a problem with reporting services, running local rdlc files on the 2005 version.
I have in the HTML a report viewer set to run locally as follows :
<rsweb:ReportViewer ID="ReportingServicesReportViewer" runat="server" Height="100%"
ProcessingMode="Local" ShowParameterPrompts="False" Width="100%">
</rsweb:ReportViewer>
// create SqlConnection
SqlConnection myConnection = new SqlConnection(ConnectionString);
myCommand.Connection = myConnection;
SqlDataAdapter da = new SqlDataAdapter(myCommand);
//get the data
DataSet data = new DataSet();
da.Fill(data);
if (data != null && data.Tables.Count > 0 && data.Tables[0].Rows.Count > 0)
{
ReportingServicesReportViewer.Visible = true;
ltrStatus.Text = string.Empty;
//provide local report information to viewer
ReportingServicesReportViewer.LocalReport.ReportPath = Server.MapPath(Report.RDLCPath);
//bind the report attributes and data to the reportviewer
ReportDataSource rds = new ReportDataSource("DataSet1", data.Tables[0]);
ReportingServicesReportViewer.LocalReport.DataSources.Clear();
ReportingServicesReportViewer.LocalReport.DataSources.Add(rds);
ReportingServicesReportViewer.LocalReport.Refresh();
}
else
{
ReportingServicesReportViewer.Visible = false;
ltrStatus.Text = "No data to display.";
}
Try using a simple report , sometimes reportviewer throws exception caused by invalid RDLC and shows an empty report.
Try also to debug the project and look at the output window in Visual Studio: you will see the warning raised bu the RDL engine, it could be useful to investigate the reason of the error.
