修复亚音速2.2日历时,如何使RegisterClientScriptInclude调用在控件不可见时呈现?

here .

所以我做了任何开发人员都会做的事情,我刷了日历的所有代码,并把它放在自己的库中。

不幸的是,日历不能很好地使用更新面板。
我得到了帮助 here 但是,为了让日历在更新面板中工作,我仍然有一个问题,如果日历在更新面板中,并且在第一次请求时不可见,则指向JavaScript文件的脚本标记不会呈现。

    protected override void OnPreRender(EventArgs e)
    {
        string csslink = "<link href='" + Page.ClientScript.GetWebResourceUrl(GetType(), IncludeAssemblyPrefix + "skin.theme.css") + "' rel='stylesheet' type='text/css' />";
        Page.Header.Controls.Add(new LiteralControl(csslink));
        Page.ClientScript.RegisterClientScriptInclude("CalendarMain", Page.ClientScript.GetWebResourceUrl(GetType(), IncludeAssemblyPrefix + "calendar.js"));
        Page.ClientScript.RegisterClientScriptInclude("CalendarSetup", Page.ClientScript.GetWebResourceUrl(GetType(), IncludeAssemblyPrefix + "calendar-setup.js"));

        string langPrefix = IncludeAssemblyPrefix + "lang.calendar-";

        if (String.IsNullOrEmpty(Language))
            Language = DEFAULT_LANGUAGE;

        if (Assembly.GetExecutingAssembly().GetManifestResourceStream(langPrefix + Language + ".js") == null)
            Page.ClientScript.RegisterClientScriptInclude("CalendarLanguage", Page.ClientScript.GetWebResourceUrl(GetType(), langPrefix + DEFAULT_LANGUAGE + ".js"));
        else
            Page.ClientScript.RegisterClientScriptInclude("CalendarLanguage", Page.ClientScript.GetWebResourceUrl(GetType(), langPrefix + Language + ".js"));

        base.OnPreRender(e);
    }
    public string IncludeAssemblyPrefix { get { return Assembly.GetExecutingAssembly().GetName().Name + "."; } }

所以我的问题是,当控件不可见时,如何让RegisterClientScriptInclude调用工作?
