Parameters

index

The zero-based index of the item to scroll into view.

You can use this method to ensure that a specific item is visible within the RasterImageList control. When performing validation on the items in a RasterImageList, you can call the RasterImageList.EnsureVisible method to ensure that an item that failed validation is displayed in the RasterImageList control to allow the user to perform changes on the item. If the item that you want to ensure is visible is located above the viewable region of the RasterImageList control, calling the RasterImageList.EnsureVisible method will scroll the contents of the control until it is the first item in the viewable area of the control. If the item is below the viewable region of the RasterImageList control, calling the RasterImageList.EnsureVisible method will scroll the contents of the RasterImageList control until the item is the last item in the viewable area of the control.

To determine if an item is located at the top of the display area of a RasterImageList control, use the TopIndex property.
