在事件中给控件传js参数事件时参数"'"被html格式化的处理方法
在listview的created事件中，给dropdownlist传onchange事件
- C# code
TextBox tbUserName=(TextBox)e.Item.FindControl("tbUserName")ddl.Attributes["onchange"]="myonchange(this,'"+tbUserName.ClientID+"')"但onchange事件执行不成功，看浏览器生成的源码发现tbUserName.ClientID生成的字符串的前后两个'都变成了html字符，用HttpServerUlity.decode转换都不行，我用的是vs2010，但我看视频时别人用vs2008好象没有出现问题，或者是IIS内部进行了处理，请教该如何处理。
[解决办法]
'会变成#&39之类的，不影响参数的使用的，
另外，请换成ItemDataBound事件，ItemCreate事件传的id是错误的
例子
- HTML code
