Checkbox does not remained checked

hey In the code I have here, I need to set the checkbox state from a database but I dont know the properties:

while (l_objRead.Read())
{
                         //txtUserName.Text = l_objRead["UserName"].ToString().Trim();
                         txtWerknemerNaam.Text = l_objRead["Naam"].ToString().Trim();
problem here => cbAktief.CheckState = l_objRead["Aktief"];
}

I am currently trying to write some code that allows an admin to add users to a system by selecting a checkbox and then clicking a button at the top of the screen that will allow for a mass user add.  I am new to ASP and am trying to figure out how to make the system recognize each checkbox that is checked only to add to the database.  Any ideas on where to start on this?  Thanks

How do I use the jQuery set

If checkbox's value in the string (cbx1, cbx2, cbx5, cbx7),

set the checkbox is checked.

Thank you

hi guys.

I have a checkbox on my project and I have textboxes as well. I tried some jquery code as you can see below for this function;

I would like to get the ctl00$MainContent$firstnametxt.text value to ctl00$MainContent$firstnamedrivertxt.text value when the checkbox is clicked and I want the ctl00$MainContent$firstnamedrivertxt.text to be null if the checkbox is unchecked. how can I do that? the below one doesn't work for me.

<script type="text/javascript">
    //var myspan = $('#MyCheckBoxHere');

    $('#ctl00_MainContent_CheckBox1').click(function () {

        if ($(this).is(':checked')) {
            $('ctl00$MainContent$firstnamedrivertxt').text($('ctl00$MainContent$firstnametxt').text);
        }
        else {
            $('ctl00$MainContent$firstnamedrivertxt').text(null);
        }
    });
</script>

My checkbox is rendered without a check mark.  If I use only one checkbox (instance object) to render then I can get the check mark to show, but I cannot use this solution.  I need be able to render it using the local checkbox.  This checkbox has the Aero theme applied to it by default and this is also a must have for me.  Other themes built-in themes like Royal, and Luna render with a check mark.
