Public NotInheritable Class ToggleImage
public sealed class ToggleImage
Remarks
The image is always displayed if the texbox is a toggle item for another report item. If no ToggleImage element is present, no image is displayed. The toggle image displays as a plus sign (+) to indicate a collapsed state with hidden report items, and as a minus sign (-) to indicate an expanded state with all report items visible. Whenever the textbox or image is clicked, the toggle image state flips and the image associated with the new state is displayed instead.
