ImageCheckBox
The SharpPieces ImageCheckBox control is a small, easy to use control, with client side library, which is designed to make the checkbox form elements more appealing to the end users. You can style it in whatever way you find it suitable, or use the existing design.
You can also use the built-in autopostback feature, just like you would with a normal checkbox.
Using the OnClientBeforeChange and the OnClientAfterChange you can attach custom javascript function, to prevent click based on business logic, or to update elements of the page when the control gets checked
