从C＃代码后面调用Javascript不起作用

Question

我一直在使用相同的Page.clientScript从代码隐藏调用javascript来引用其他项目中的这个链接Calling javascript function from Codebehind并且它已经工作了，但它现在在我当前的项目中不起作用。

这是我的c＃代码：

protected void Page_Load(object sender, EventArgs e)
{
    Page.LoadComplete += new EventHandler(Page_LoadComplete);
}

void Page_LoadComplete(object sender, EventArgs e)
{
    System.Diagnostics.Debug.WriteLine("Page Loaded");

    var namespaceManager = NamespaceManager.CreateFromConnectionString(connectionString);

    if (!namespaceManager.SubscriptionExists(CID, "AllMessages"))
    {
        namespaceManager.CreateSubscription(CID, "AllMessages");
    }

    System.Diagnostics.Debug.WriteLine("Sub Existed : " + namespaceManager.SubscriptionExists(CID, "AllMessages"));

    client = SubscriptionClient.CreateFromConnectionString(connectionString, CID, "AllMessages");

    // OnMessageOptions eventDrivenMessagingOptions = new OnMessageOptions();            
    // eventDrivenMessagingOptions.ExceptionReceived += OnExceptionReceived;            

    client.OnMessage(OnMessageArrived);
}

void OnMessageArrived(BrokeredMessage message)
{
    System.Diagnostics.Debug.WriteLine("++++++++++++++++++++");
    System.Diagnostics.Debug.WriteLine(message.GetBody<UpdateData>().data);
    Page.ClientScript.RegisterStartupScript(this.GetType(), "CallMyFunction", "MyFunction()", true);
}

static void OnExceptionReceived(object sender, ExceptionReceivedEventArgs e)
{

}

谢谢。
