I'm using UI for WinForms R1 2017 and have observed a problem with the drawing of RadTimePicker when in a disabled state (Enabled = false).
Please see the attached picture. Notice how the RadDateTimePicker control (on the left) has the expected disabled appearance. However, the RadTimePicker control (on the right) does not. Specifically, part of the RadTimePicker editor background is still drawn in a light color when the control is disabled.
Please let me know if there's a workaround for this, and thanks.
