上次的问题如下：

按你的方法已经解决了，然后我想在用户修改文本框的值后通过button调用自定义服务器控件中的一个方法将值保存到数据库中，但我用Page.Request.Params[Clientid].toString()取值时总是说'未将对象引用设置到对象的实例',是不是不能用此办法来获取，Waiting.....(再次感谢!)

try

Page.Request.Params[UniqueID]

ClientID --> id
UniqueID --> name --> goes into Request.Form

if you are outputting html yourself, then set its name field besides the id field:
(aaa can be same as bbbb)
"<input type=text id=aaa name=bbbb value=123>",

then on the server side, you do Request.Form["bbbb"]. The reason to use UniqueID/ClientID is that the system will always genereate unique id/names. For example, if you put two copies of your controls, with ClientID/UniqueID, their id/name will be different on the client side, but if you are outputting html yourself, they end up with same id/name, and that can cause problems when you are doing client side scripting or when you are retrieving the data on the server side

太感谢了，这两次通过你的指点已经解决了，再次感谢!!!
