Property Value

Type: System.String
The key of the default image shown when a TreeNode is in a selected state.

If a TreeNode does not have a selected image set, the image specified by the SelectedImageKey property will be shown when the node is not selected.

The SelectedImageKey and SelectedImageIndex properties are mutually exclusive; if one is set, the other is ignored. If you set the SelectedImageKey property, the SelectedImageIndex property is automatically set to -1. Alternatively, if you set the SelectedImageIndex property, the SelectedImageKey is automatically set to an empty string ("").
