The HiddenField Web server control provides a container control within a Web Forms page that you can use as a parent for static text and for other controls. The HiddenField control is suitable for:

• Group Behavior   You can manage a group of controls as a unit by putting them in a hiddenfield and then manipulating the hiddenfield. For example, you can hide or show a group of controls inside a hiddenfield by setting the hiddenfield’s Visible property.
• Dynamic Control Generation   The HiddenField control provides a convenient container for controls that you create at run time.
• Appearance   The HiddenField control supports appearance properties such as BackColor and BorderWidth that you can set to create a unique look for a local area on a page.
