I had a chance to compose the post about the styling of TextField. Unfortunately, my plans changed and I had no time to work on the articles. Now, I got some bandwidth so I decided to get back to the original plan. In this article, I will provide code, instructions, and an example of a fully functioning component that you can use when you work on your controls on how to make DatePicker field to lookalike native UCI control.
