If you set a validation control's , stating: "Control 'control ID' referenced by the Control To Validate property of 'validation Control ID' cannot be validated." There may be times, however, when you need to provide validation for a Check Box or Check Box List.

Many Web pages with Terms of Service include a Check Box titled "I agree to the above terms" that must be checked before continuing.

If you are too lazy or in too big a hurry to create your own validation control, you can quickly whiff up a validation scenario using an asp: Custom Validator. w=560" class="size-full wp-image-1058" title="Validation Error" src="https://briancaos.files.wordpress.com/2012/08/validationerror.png? w=640" alt="" srcset="https://briancaos.files.wordpress.com/2012/08/560w, https://briancaos.files.wordpress.com/2012/08/validationerror.png? w=150 150w, https://briancaos.files.wordpress.com/2012/08/validationerror.png? w=300 300w" sizes="(max-width: 560px) 100vw, 560px" / The custom validator will now execute the validation on server side. Is Valid to ensure that all validations are successfull.

SETUP THE LIST AND THE VALIDATOR: First the Check Box List: Validation Error " data-medium-file="https://briancaos.files.wordpress.com/2012/08/validationerror.png? w=300" data-large-file="https://briancaos.files.wordpress.com/2012/08/validationerror.png? APPLY CLIENT-SIDE VALIDATION: The Custom Validator has also a client-side Java Script referenced in the Client Validation Function property.

This Java Script looks like this: Please also note that since the Control To Validate property cannot be used on a Check Box List you need to hard-select the client ID of the Check Box List in the Java Script.

Update March 11 2016: Updated the code to add client side validation after a few comments pointed out that the default jquery range validator expects numbers and doesn't play nicely with bool parameters (ie.

When you run the page and click one of the buttons, you will see that the checkbox will have a Required Field Validator. But it works only on serversde, requiring a postback to use it.

We can do that via Custon Validator Control on ASP. But the solution I posted for Checkbox validation is much more simple I guess What do you think? You can simply download the dll, inlcude it in the Visual Studio (Web Developer) Toolbox and then you can drag and drop it anywhere you like, so it is a simple to use as any other validation control, including client and server side validation as you would expect from a validator control.

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 !
