I created a new template for the RadDateTimePicker because I overrided the Clock Part.
As part of the changes I added a Tooltip which shows the date time if not null. In the Watermark control part of the template I show the SelectedValue property that is bound to the ViewModel - TwoWayBinding. The string format of the DateTime is full date: dd/MM/yyyy with full time: HH:mm:ss. So I see the parsed Text on the control.
I can't find an easy way to show the tooltip in the same format as the display date. I can't set the Tooltio content to RelativeSource Path=SelectedValue because it shows the DateTime in orginal format.
I also can't show in the Tooltio the DisplatText because even if binding OneWay, the date is flickering in every change like binding is wrong.
In the Style of the RadDateTimePicker I have access to SelectedValue, SelectedDateTime,SelectedTime properties but it seems that you convert the Date Time to a text inside the control code because it doesn't work on the Tooltip.
Do you have any solution for that?
