我认为可以使用
禁用另一个控件没有回发的JScript / VBScript，但这里有点偏离主题。

I assume that it''s possible to disable another control using
JScript/VBScript without a postback, but that''s slightly off-topic here.

Geoff，
这听起来像是在谈论ASP.NET。
正如Herfried所说。如果你想在服务器方面做，那么你需要回复
。如果您不想要回发，那么您将不得不使用JavaScript或VBScript进行客户端
。
有关客户端JavaScript的帮助&安培; VBScript你可能想问这个
在大厅里在microsoft.public.dotnet.framework.aspnet
新闻组之一。
希望这有帮助

Geoff,
It sounds like you are talking ASP.NET.
As Herfried suggests. If you want to do it server side, then you need to do
a postback. If you don''t want a postback, then you will have to do it client
side with JavaScript or VBScript.
For help with client side JavaScript & VBScript you may want to ask this
"down the hall" in one of the microsoft.public.dotnet.framework.aspnet
newsgroups.
Hope this helps
