Whenever i going to add reportsource for the subreport it gives me error of "Object reference not set to instance of a object"

Hi Manoj,

This error means that there is a problem with the report you are trying to assign. Run it in preview to see the problem or assign it programmatically for a full stack trace that would point you to the problem e.g.

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        Report1 report1 = new Report1();
        ReportViewer1.Report = report1;
    }
}

Best wishes,
