Net validating checkbox
Suppose you have to disable password’s requiredfieldvalidator when ‘Allow me‘ checkbox is true.
Shows you how to write a script that ensures your form is filled in correctly before it's sent to your server.
Great for "required fields" such as email addresses!
We want to the user to agree to our imaginary Terms and Conditions before they send the form, so we'll check to make sure they've clicked the checkbox: in any one of the above cases, if one or more of our checks fail, the form will not be sent to the server.So, you have to do SAME on server side before calling validate method.
