Remarks

The image key returned by this property is contained in the ImageList property of the containing TreeView control.

The ImageKey is case-insensitive.

ImageKey and ImageIndex are mutually exclusive, meaning if one is set, the other is set to an invalid value and ignored. If you set the ImageKey property, the ImageIndex property is automatically set to -1. Alternatively, if you set the ImageIndex property, the ImageKey is automatically set to an empty string ("").
