1. I dont know how to assign a new display or a new AttrText to droplist. Please could you help me again with a code example?
2. Why UPP controls doesnt have the same methods like in VB, say, .SetColor(), .SetBakGround() ?

1. Please use forum search. This topic was discussed a number of times. If you don`t find any, write here, I`ll try to help finding one.
2. U++ uses slightly different approach to customizing controls than VB. This technology is called Chameleon.
The main idea is that control is assigned to the complex customization object, which is constructed from native OS drawing styles & colors. Complexity of this object is explained by the fact that modern operating systems have very complex rules for drawing widgets. These rules include many colors and many styling rules (which may include even opacity and gradients).
So when you want to change look&feel, you generally need to alter this complex customization Style object. Please be prepaired to alter a number of colors, not just one - if you want your custom widget to look great in a number of modern operating systems.
