I found the solution. Manually add the Page_Init() event and wire it up in the InitializeCompnent() with

this.Init += new System.EventHandler(this.Page_Init).

Move the contents of Page_Load to Page_Init().

Add if (!IsPostBack) condition in PageInIt.

protected void Page_Init(object sender, EventArgs e)
{

        if (!IsPostBack)
        {
             ReportDocument crystalReportDocument = new ReportDocumment();
             crystalReportDocument.SetDataSource(DataTableHere);
             _reportViewer.ReportSource = crystalReportDocument;
             Session["ReportDocument"] = crystalReportDocument;
        }
        else
        {
              ReportDocument doc = (ReportDocument)Session["ReportDocument"];
              _reportViewer.ReportSource = doc;
        }
   }
