Remarks

When the ButtonType property of a CommandField field is set to ButtonType.Image, use the UpdateImageUrl property to specify the image to display for an Update button. This image can be in any file format (.jpg, .gif, .bmp, and so on), as long as the client's browser supports that format.

Napomena

As an alternative to displaying an image for an Update button, you can display text by first setting the ButtonType property to ButtonType.Button or ButtonType.Link and then setting the UpdateText property.
