MahApps DateTimePicker custom datetime format

Question

I am using the DateTimePicker control of MahApps.

<controls:DateTimePicker 
    SelectedDate="{Binding SelectedDateTime, RelativeSource={RelativeSource AncestorType=UserControl}}" 
    SelectedTimeFormat="Short" 
    SelectedDateFormat="Short"
    Culture="en-In"/>

Currently it's showing datetime in dd-mm-yyyy HH:mm format.But I need to show that in yyyy-mm-dd HH:mm Z format. I see currently it has no property which takes datetime format as string pattern. So how to do this?

Answer 1

Yeah, the control doesn't support this. You can override the GetValueForTextBox method to achieve this

public class MyDateTimePicker : DateTimePicker
{
    protected override string GetValueForTextBox()
    {
        return SelectedDate?.ToString("yyyy-MM-dd HH:mm Z");
    }
}

XAML

<local:MyDateTimePicker />
