Regarding the decoration of the ASP DropDownList, what RadFormDecorator does initially is to hide it and then create its own DOM elements, so that the DropDownList looks decorated:
- The header of the dropdown is visualized inside a span, wrapped in a link tag
- The expanded dropdown is visualized inside an unordered list, wrapped inside a div tag.
You can find the full list of the CSS classes that RadFormDecorator uses for the decoration here.
This means that directly formatting a decorated select is not possible. If you need to modify your selects you can skip them by setting ControlsToSkip="Select" for the decorator.
All the best,
