Dynamic Read Only in applet

Hi,

I have a requirement to make the fields read only in applet level dynamically.

Can you please suggest the best way to do it.

So the requirement is simple, when ever user ticks on Check Box, some text boxes must become read only.

And we must not save that data. I am able to achieve this using applet user property - Read only field, it is making text boxes as labels.

And another problem is, if you already enter values into text fields and then tick the checkbox then the fields become read only but when we save the object we are also saving the read only fields which must not happen.
