使用 TabPanel.OnClientClick 实现 TabContainer 实现按需加载，代码如下：

注意：OnClientClick 指定的方法是不能带()的，所以不能指定参数，否则你将得到两个脚本错误：
                Sys.InvalidOperationException: Handler must be a function.
                Sys.InvalidOperationException: Handler was not added through the Sys.UI.DomEvent.addHandler method.
此错误参考：Event handler Javascript error: Sys.InvalidOperationException: Handler must be a function (CalendarPopupExtender)
