Remarks

Use the Caption property to specify the text to render in an HTML caption element in a GridView control. The text that you specify provides assistive technology devices with a description of the table that can be used to make the control more accessible. You can also specify the position at which to render the HTML caption element by using the CaptionAlign property.

The value of this property, when set, can be saved automatically to a resource file by using a designer tool. For more information, see LocalizableAttribute and Globalization and Localization.
