Parameters

item: The item within the RasterImageList whose bounding rectangle you want to retrieve.

Return Value

A System.Drawing.Rectangle that represents the bounding rectangle of the specified RasterImageListItem.

The bounding rectangle returned by this method represents the entire item.

The bounding rectangle that this method returns could contain a negative position or could be outside the client rectangle of the control. The exact position of the item depends on the current size of the control as well as the current scroll position.

This example will highlight the position of all visible items a RasterImageList control.
