Remarks

When the ButtonType property of a CommandField field is set to ButtonType.Image, use the NewImageUrl property to specify the image to display for the New 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.

Note

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