我正在使用visual studio 2010，我安装了水晶报告在它里面。我想根据通过dropdownlist传递的值来运行报告，该报告绑定到数据库。虽然我得到报告无论我在
下拉列表中选择的第一项，但是当我选择任何其他值时无法获得报告。这是我正在使用的代码

I am using visual studio 2010 and I installed crystal reports in it as well. I wanted to run a report based on the values passed through dropdownlist which is bound to a database. Although i get the report whatever the first item i select in the dropdownlist but not able to get the report when i select any other value. Here is the code which i am using

private ReportDocument report = new ReportDocument();
protected void Button1_Click(object sender, EventArgs e)
        {
            // get the selected CategoryID
            int categoryID = Convert.ToInt32(DropDownList1.SelectedValue);
            //report.SetParameterValue("CategoryID", categoryID);
            ///CrystalReportViewer1.ReportSource = report;
            ReportDocument report = new ReportDocument();
            report.Load(Server.MapPath("CrystalReport1.rpt"));
            report.FileName = Server.MapPath("CrystalReport1.rpt");
            report.SetParameterValue("CategoryID", categoryID);
            CrystalReportViewer1.ReportSource = report;
        }

I am able to get the said report in crystal report when i enter different values as parameters in the crystal report file but not able to get the required report in the web form.
