);

Answer 2

<input type="checkbox" id="cb" />
<label for="cb">label for checkbox</label>
<input type="text" id="txt" disabled="disabled" />

<script type="text/javascript">
    $(document).ready(function() {
        var checkbox = $('#cb');
        var textfield = $('#txt');

        checkbox.click(function() {
            if (checkbox.is(':checked')) {
                textfield.removeAttr('disabled');
            }
            else {
                textfield.attr('disabled', 'disabled');
            }
        });
    });
</script>

working example with visibilty
working example with disabled-state

additionally: as you are working with asp.net, your assignments should look like, eg:

var checkbox = $('#<%= this.cb.ClientID %>');

you should be aware of the way how the server-controls get rendered either (to choose an appropriate selector).
furthermore: you should also be aware of the fact, that disabled-inputs won't get posted, whereas readonly-inputs are no problem to handle...

Answer 4

$(document).ready(function() 
{
    //To Disable the Check box on page Load
    $('#TextBox').attr('disabled', 'disabled');     

    //On Click of the Check Box 
    $('#CheckBoz').click(function() 
    {
        if($('#CheckBoz').is(':checked'))
        {
            $('#TextBox').removeAttr('disabled');            
        }
        else
        {           
            $('#TextBox').attr('disabled', 'disabled');            
        }    
    });
});

I Hope this code works perfectly for you and u jst need to paste it in your page and check the Component name according to it.
