Hello Paul Ridden,
Thank you for submitting your concerns.
The display of the tooltip that you see is intended. This is not the regular Validation tooltip
(which indeed is red with red foreground), but a Suggestion tooltip
By default, text input is enabled for RadDateTimePicker
, because you have the option to enter for instance "3 September
" and the tooltip will update its value to suggest 9/3/2010
Additionally, the ParseDateTimeValue
is raised on lost focus because text should be parsed after one has finished entering input and this is intended default behavior.
We understand that such a behavior is not the optimal for your scenario and we will strive to improve the control validation in our upcoming releases (by the way, RadDateTimePicker is a new control from our Q2 Release).
What you could do for now is to create an attached behavior which sets the SelectedValue
of RadDateTimePicker to null
on some condition and as a result throw an exception
so that you will be able to see the Validation tooltip.
Please, get back to us with any further questions.
