Hi,
 
Is there a way to display null dates in a DateTimePicker? Maybe I can set a custom format when the DateTime value is null. How do I set the custom format to only show day? Maybe there is an easy solution. I tried Enabled=false but it still shows a date also tried to set forecolor=backcolor but that does not work.
Thanks,
Sander

Hello Sander,

Please view this article here for details on how to only display day values in the DataTimePicker control using CustomFormat.

It may be very helpful if you could please describe to me what is it that you are trying to accomplish in the flow UI, and what is the scenario you are constructing in your application. It would greatly help me to see the bigger picture. I would be able to either, open an issue for required changes in our framework, or suggest to you the best implementation available to achieve what you want in your VWG application.

Hi Ori,

I can give you a business case as I am having the same problem as Martin, and I really need a DateTimePicker where I can display an empty box as opposed to a date.

I have a database application where users can search through records of Emergency Ambulance (hint Magen Dovid Adom) calls.  When they start the application, all the different search fields are blank, because it is showing all records by default.  This includes the filters for Start Date and End Date.  Right now, the only way I could think of to NOT search on these fields by default, was to set both of them to the next day (so if a user goes into the application today, the 24th, the DateTimePickers would show tomorrow's date, the 25th).   My application knows to ignore the dates in the search filter if they are greater than today's date.  But, if I had the ability to show an empty (null) value in the DateTimePicker, then I could just exclude them from the searches if they don't have a value. 

That would be a much more intuitive implementation from a user's perspective, as opposed to me having to explain to them why the date fields are set to tomorrow's date by default.

Thanks,
