R – DateTime in PropertyGrid in .Net

datetimepropertygrid

I'm currently working on some DateTime properties in a PropertyGrid in c#.Net. Im using the default drop-down datetime picker.

My question: Is there any way to show the full date with the time? By default the date is shown if no time is set, but I want zero-values aswell. I.e: I want "09.11.2009 00:00" to be shown instead of "09.11.2009".

Do I have to use some custom TypeConverter or Editor for this?
I feel so lost in this propertygrid and it makes me sad…

Any help would be appreciated! Thanks 🙂

Yes, you need your own TypeConverter. Derive it from DateTimeConverter and override the ConvertTo method. If you look this method in Reflector you will see this piece of code inside:

if (time.TimeOfDay.TotalSeconds == 0.0)
    return time.ToString("yyyy-MM-dd", culture);

Just remove that for example.

C# – How to calculate someone’s age based on a DateTime type birthday

An easy to understand and simple solution.

// Save today's date.
var today = DateTime.Today;

// Calculate the age.
var age = today.Year - birthdate.Year;

// Go back to the year in which the person was born in case of a leap year
if (birthdate.Date > today.AddYears(-age)) age--;

However, this assumes you are looking for the western idea of the age and not using East Asian reckoning.
