DateTimePicker - Format

[pavelkocich]

It will be great if I can set DateTime format of string shown in DataPickerTextbox.

• MahApps.Metro __v1.3.0-ALPHA189
• Windows 10
• Visual Studio 2015
• .NET Framework 4.5

Can you be more specific?

Set Culture property. DateTimeFormat property is also not present on DatePicker

[pavelkocich]

I can set Culture property of course, but it will be great to have more straightforward solution with property e.g. StringFormat, like Label control.

<Label ContentStringFormat="dd.MM.yyyy hh:mm" Content="{Binding MyDateTime}"/>

<controls:DateTimePicker StringFormat="dd.MM.yyyy hh:mm" SelectedDate="{Binding MyDateTime}" />

Since this feature still is not implemented, are there any quick fixes that I could use instead? For example, I am using Culture sv-SE which gives me a date-time format yyyy-MM-dd HH:mm:ss. However, I don't want to display the seconds. Is there any way I can accomplish this using the Culture property only?

@anders9ustafsson As a workaround you can override the time pattern with at a custom CultureInfo, cause the DateTimePicker uses this to format the text

var dateTimeFormat = string.Intern($"{formatInfo.ShortDatePattern} {formatInfo.LongTimePattern}");

e.g.

var ci = new CultureInfo("sv-SE");
ci.DateTimeFormat.LongTimePattern = ci.DateTimeFormat.ShortTimePattern;

then set this to the Culture property of the DateTimePicker.

/cc @xxMUROxx This should be easier to do in future release...

@punker76 Thanks for the suggestion! I'll try it out.
