I'm attempting to use the RadMaskedDateTimeInput control, using a mask of "g", which provides date and time input with the AM/PM indicator. It appears that the AM/PM indicator can only be changed using the up/down arrows when SpinMode is enabled. There does not appear to be a way to change the AM/PM value via the keyboard - for example, typing "A" or "P" when the caret is in that position. So if SpinMode is disabled, then there is no way to update the value at all.
Is this a bug or is there another way to change the AM/PM indicator?
