Hi I am having problem displaying Chart Image inside the Image viewer.
I have used one report1.rdlc file and placed on pie chart inside of it. In the reportviewer I have added this report1.rdlc as report and on button click wrote the folowing code:

ReportViewer1.LocalReport.DataSources.Clear();
           ReportDataSource rds = new ReportDataSource();
           rds.Name = "DataSet1";
           rds.Value = GetReportDataByProduct();
           ReportViewer1.LocalReport.DataSources.Add(rds);

But the problem here is when debugging I am able to see texts inside the report, but not the image.

I need help...
