ASP.net失败RegisterClientScriptBlock

Question

当我试图在我的跟踪中注册这个脚本时，它说它没有注册，尽管我在这里感叹它的注册：

Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "DrillThrough report " + (int) dr["ReportID"] + " script", vbs_script);

脚本文件名为DrillThrough6-0.Function.BT.SS2005.ReportID42193.vbs，可能会出错。另外，如果我使用开发人员工具运行Internet explorer (可能只是巧合，但它总是只在打开开发工具时发生)，它就会注册得很好。并且按照它的设想运行，否则它根本不运行。

上下文代码：

SqlDataReader dr = PivotTableDB.GetReport(drillThroughReportID);
        Trace.Warn("Attempting to Read... ");
        if (dr.Read()) {
            Trace.Warn("Reading... ");
            Page.ClientScript.RegisterHiddenField("txt_DetailReportCubeName", (string) dr["CubeName"]);

            string path = (string) this.MapPath("~/DesktopModules/PivotTableNav/DrillThroughReportScripts/");
            string name = (string) dr["DisplayName_en"] + ".ReportID" + (int) dr["ReportID"] + ".vbs";
            string vbs_script = "";

            if (File.Exists(path + name)) {

                StreamReader sr = new StreamReader(path + name,System.Text.Encoding.GetEncoding("iso-8859-1"));
                vbs_script = sr.ReadToEnd();
                vbs_script = vbs_script.Replace("Spreadsheet1","document.Form1.Spreadsheet1");
                vbs_script = vbs_script.Replace("for=document.Form1.Spreadsheet1","for=Spreadsheet1");
                sr.Close();
            }

            if (vbs_script != null) {
                Trace.Warn("vbscript", vbs_script);
                Trace.Warn("vbscript-path", (path + name));
                Trace.Warn("vbscriptExist", "File exist: " + File.Exists(path + name) + " BlockRegistered already: " + Page.ClientScript.IsClientScriptBlockRegistered("DrillThrough report " + (int)dr["ReportID"] + " script"));
                if (! Page.ClientScript.IsClientScriptBlockRegistered("DrillThrough report " + (int) dr["ReportID"] + " script"))
                    Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "DrillThrough report " + (int) dr["ReportID"] + " script", vbs_script);
            }
            Trace.Warn("Was vbscript Registered: " + Page.ClientScript.IsClientScriptBlockRegistered("DrillThrough report " + (int)dr["ReportID"] + " script"));

            Title.Text = LanguageUtils.ChooseOnLanguage(dr["DisplayName_en"].ToString(), dr["DisplayName_fr"].ToString());

        }
        else { Trace.Warn("Did not read the report since no data no rows: "); }
        dr.Close();

为了实现这个目标，我将RegisterClientScriptBlock改为了RegisterStartupScript。现在寄存器成功了，直接将isClientScriptBlockRegistered更改为IsStartupScriptRegistered。
