Issue with SSRS Loading Report from Definition From Assembly

I am using SharePoint 2010. I created web-part where there is report viewer control. On the page load of the control. I am writing below codes to load report from definition. Web part is not giving any error but also not loading report. I tried to make physical report file from my stream and I found that report is correct.

But I don't know what is missing.

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            Assembly assembly = Assembly.Load("Reports, Version=1.0.0.0, Culture=neutral, PublicKeyToken=f51c855eec632536");
            Stream stream = assembly.GetManifestResourceStream("Reports.Reports.rdlc");
            MemoryStream rdl = new MemoryStream();
            CopyTo(stream, rdl);

            rptInspectorPlan.Reset();
            rptInspectorPlan.LocalReport.LoadReportDefinition(rdl);
            rptInspectorPlan.LocalReport.DataSources.Clear();

            rptInspectorPlan.LocalReport.DataSources.Add(new ReportDataSource("MyData", finalData(getInspectionPlan())));
            rptInspectorPlan.LocalReport.Refresh();
        }
    }

    protected DataTable getInspectionPlan()
    {
        DataTable dt = new DataTable();
        DataTable dtCurrentUser = getCurrentUser();
        using (SPSite site = new SPSite(getMarketSurveillanceURL()))
        {
            using (SPWeb web = site.OpenWeb())
            {
                SPList list = web.Lists.TryGetList("InspectionPlan");

                string query = "<Where><Eq><FieldRef Name='Title'/><Value Type='Text'>" + dtCurrentUser.Rows[0]["ID"].ToString() + "</Value></Eq></Where>";//getCurrentUserID()
                oQuery.Query = query;
                dt = list.GetItems(oQuery).GetDataTable();
