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.
