Custom layout when in AbsoluteLayout container
IF the CheckBox control is placed in an AbsoluteLayout container, individual controls can be manually positioned if this option is selected.
Controls placed in an Absolute AbsoluteLayout container can be positioned manually to appear in a fixed location within the container. If the CheckBox control is populated with static data, the position of each check box in the control can be positioned "absolutely". An AbsoluteLayout contaienr is often used in web applications to add controls over a background image, such as a tax document or hospital form.
The Custom layout when in AbsoluteLayout container option is only available if the choices for the control are defined using a static list.
Make sure the Label Position for the CheckBox control is set to None when using this option.
