There are the following two types of validation in ASP. So, validation is a good idea to do whenever we are taking input from the user.
Net has bunch of useful validation controls and they realy make our project so easy in terms of validations. Net doesn't have any control to validate a check box !This becomes a problem when you want to validate the group, since you can’t set a common name attribute for all the elements.Here is an example of the HTML that would be rendered by a Check Box List with a layout of “Flow”. If we get the user input with validation, then chances are that we are sending the wrong data. Whenever the user gives the input, it must always be validated before sending it across to various layers of an application.
Now my issue is when I simply enter text to the 1st Text Box and click save, the button click is validating the required field for hidden field.
