thank you for your response, but I think I was a little unspecific there. Sorry!
We need to restrict the date range on a monthly or daily basis and additionally the user shouldn't be able to enter a wrong date in the input field by typing it in. The pega setting only restricts the date picker.
Regarding the format we need the dots to appear while the user types. For example if a user types on his keyboard "01012019" the input control would look like this "01.01.2019" without the user ever hitting his "." key. Doing a save as on the pxDateTime control I don't think there is a way this would let the dots appear automatically while the user types.
