As i have used asp:checkbox, it ristricted me to access it.

In the case of a checkbox multiple values can be selected so validation is done if none of the checkboxes are ticked.

You can also validate by requiring the user to select a minimum of one value or two value according to your requirement.

Format("return validate Check Boxes In Grid('');", Grid View1. In Javascript we create a function which checks if some value is entered in the textbox or selected in the case of combobox, radiobutton, checkbox.If a textbox is empty or an option is not selected we can use javascript to display an alert message, and highlight the empty field and also we should make sure the page stays the same and doesn’t get “submitted” Javascript validation is a client side validation and relies on the web browser so it should not be solely relied upon Textbox is the simplest element to validate if empty or not.I would like to show an alert if no check box was checked in a field.

The idea is that at least one check box should be checked.I have an on Submit for the form and a JS function that suppose to check it but it does not work.
