RequiredFieldValidator验证禁用的textBox

Question

I've got a TextBox in which user can input a their desired username. Underneath I've got a checkbox that once clicked it copies the user's email adress into the textfield and then disable it to prevent further changes. This feature is implemented by using jQuery.

The problem is that I've got a RequiredFieldValidator on that TextBox and it looks like it can't validate a disabled textfield, even if the value is set.

How can I solve this?

Answer 1

仅供将来参考：我通过设置属性“readonly”而不是“disabled”来修复此问题。

Answer 2

You could use a custom validator control like in this sample:
