I want to export evrything in a page to excel, it's just the graph that does not export. I used ChartControl graph which I downloaded.

protected void excel_Click(object sender, EventArgs e)
    {
        excel.Visible = false;

        Response.ContentType = "application/ms-excel";
        Response.AddHeader("content-disposition", "attachment; filename=CashFlow.xls");
    }
