I have a SelectBooleanCheckBox which is checked and disabled by default.... but when i click submit button, it is passing value as false....please help me to fix this?
There's something funny in what you just said. A selectbooleancheckbox renders as an HTML checkbox, and and HTML checkbox never gets sent to the server at all unless it's checked. In which case the value "checked" is sent.
A disabled control won't send back data regardless.
The secret of how to be miserable is to constantly expect things are going to happen the way that they are "supposed" to happen.
You can have faith, which carries the understanding that you may be disappointed. Then there's being a willfully-blind idiot, which virtually guarantees it.
