c# - PageMethod 未定义错误

Question

以下是我对服务器端方法调用 PageMethod 的实现。它当前正在生成此错误消息“未捕获的 ReferenceError:PageMethod 未定义”。我可以在 Chrome Javascript 控制台中看到这个错误。我的研究表明，PageMethods 最常见的问题是忘记将 EnablePageMethods 设置为“true”(这样做了)和需要重建应用程序(也这样做了)。我现在很困惑。谁能发现我做错了什么？

脚本管理器:

<telerik:RadScriptManager ID="RadScriptManager1" runat="server" EnablePageMethods="true">

ASPX:

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
<script type="text/javascript">
    function confirmCallBackFn(arg) {
        if (arg == true) {
            var firstDataItem = $find("<%=RadGrid1.ClientID %>").get_masterTableView().get_dataItems()[0];
            var PackageID = firstDataItem.getDataKeyValue("PackageID");
            PageMethod.RemovePackagePageMethod(PackageID);
                }
        else {
        }
    }
</script>

</telerik:RadCodeBlock> 

代码隐藏:

[WebMethod()]
public static void RemovePackagePageMethod(int PackageID)
{
    Inventory inv = new Inventory();
    inv.RemovePackage(PackageID);

}
public void RemovePackage(int PackageID)
{
    SBMData2.SBMDataContext db = new SBMData2.SBMDataContext();

    var boxes = from p in db.Packages
                where p.PackageID == PackageID
                select p;

    foreach (var box in boxes)
    {
        db.Packages.DeleteOnSubmit(box);
    }

    try
    {
        db.SubmitChanges();
        RadGrid1.Rebind();
    }
    catch (Exception ex)
    {
        RadWindowManager1.RadAlert("System error deleting package", 200, 200, "exception", null);

    }

尝试

PageMethods.RemovePackagePageMethod(PackageID);

(使用 s - PageMethods 而不是 PageMethod)
