I want to navigate page using toolbar in crystal report. I wrote code in Page_Init method.
protected void Page_Init(object sender, EventArgs e)
{
ReportDocument reportdocument = new ReportDocument();
reportdocument = (ReportDocument)Session["reportDocument"];
CrvATPostingSummary.ReportSource = reportdocument;
}

But it shows error like, Missing Parameter values.

I solved this problem by just binding report again in Page_Init method.

C#

if (!this.IsPostBack)
        {

        }
        else
        {
            if (Session["reportdocument"] != "N/A")
            {
                ReportDocument reportdocument = (ReportDocument)Session["reportdocument"];
                CrvATPostingSummary.ReportSource = reportdocument;
                CrvATPostingSummary.DataBind();
            }
        }
