- 由于Asp.net Ajax对于后台输出Javascript有较大限制，所以请注意以下几点：
- 在Page_Load方法中加入以下代码：（请注意要将该段代码放在IsPostBack的判断语句之外）
//
smartCalendar为控件实例
//
updatePanel为Asp.net AjaxUpdatePanel控件
//
以下为Asp.net Ajax RC1版本代码
System.Web.UI.ScriptManager.RegisterStartupScript(updatePanel, updatePanel.GetType(), smartCalendar.UniqueID, smartCalendar.InitializeScript,
false
);
- 如果页面中使用了类似于MutiView、View的控件，请确保第一个页面中一定有SmartCalendar控件，否则会有Javascript异常；如果第一页中不需要日历控件也请将其拖拽到页面上，可以通过将其加入到一个Style="display:none"的Div中，来实现日历控件的隐藏。
- 在Page_Load方法中加入以下代码：（请注意要将该段代码放在IsPostBack的判断语句之外）
