问题 Whenever I disable an NSTextField the text loses its color and changes to gray. How can I disable the text field and keep the text color? In my particular situation some words are colored red. I'd like those words to stay red when I disable. 回答1: You need to subclass NSTextField to do that.

问题 I'm getting a weird behavior with a dropdownlist when I trigger a postback. If the dropdownlist is enabled, the selected value remains the same after a postback.
