Using TemplateFields in the GridView Control

The GridView is composed of a set of fields that indicate what properties from the DataSource are to be included in the rendered output along with how the data will be displayed. The simplest field type is the BoundField, which displays a data value as text. Other field types display the data using alternate HTML elements. The CheckBoxField, for example, renders as a checkbox whose checked state depends on the value of a specified data field; the ImageField renders an image whose image source is based upon a specified data field. Hyperlinks and buttons whose state depends on an underlying data field value can be rendered using the HyperLinkField and ButtonField field types.
