RequiredFieldValidator to validate a disabled textBox

Question

Hi guys,

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

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

Answer 2

Just for future reference: I fixed this by setting the property "readonly" instead of "disabled".
