  • The demo shows how the RadTreeList control can be used with a custom non-embedded skin. If you are creating (using) a custom skin, which is based on an existing embedded skin, note that the RadTreeList uses the sprite image of the RadGrid's corresponding skin. In addition, you will need a custom skin with the same name for RadComboBox and/or RadInput and/or RadSlider, as these controls may appear in the RadTreeList pager.
