推荐答案

如果您的代码正在回发，则可以在C#中将ReadOnly设置为false.如果您想在客户端执行此操作，我建议您使用jQuery，然后您就可以执行

If your code is posting back then in the C# you can set ReadOnly = false. If you want to do it on client side I would recommend using jQuery and then you can do

(" ).attr(" ， false );

("#idOfTextBox").attr("disabled",false);

1)在您的代码后面添加一个点击处理程序，并将其绑定到Button控件.
2)在点击处理程序中，编写类似YourTextBox.readonly = false
的内容 3)就这样.

干杯.

看到您的答案是一个Web应用程序后，请参阅ryan的答案.

1) Add a click handler to your code behind and tie it to your Button control.
2) In the click handler, write something like YourTextBox.readonly = false
3) That''s it.

Cheers.
