When the ButtonType property of a ButtonField object is set to the Button or Link value, use the Text property to display static text for the caption of the buttons in the ButtonField. Each button shares the same caption.
Instead of using the Text property to display static text in a ButtonField object, you can use the DataTextField property to bind the ButtonField to a field in a data source. The values of the field are then displayed as the caption of the buttons.
Note
If the DataTextField and Text properties are both set, the DataTextField property takes precedence.
The value of this property is stored in view state.
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.
