MVC EditorFor日期不显示值

Question

I want to display a date in German date format (dd.MM.yyyy) from the model in an MVC app and provide the user a datepicker. I've gone throug a lot of the questions that have already been answered on this topic, but still can't get it to work. I tried it in Firefox and Edge, with the same results for each step.

Step 1:

Model:

private DateTime? inbetriebnahmedatum;

public DateTime? Inbetriebnahmedatum
{               
    get { return inbetriebnahmedatum; }
    set { inbetriebnahmedatum = value; OnPropertyChanged(new PropertyChangedEventArgs("Inbetriebnahmedatum")); }
}

View:

@Html.EditorFor(model => model.Inbetriebnahmedatum, new { htmlAttributes = new { @class = "form-control", placeholder = "Datum eingeben" } })

Result: No Datepicker, Time is displayed, Validation error

Step 2: Added DataType

Model:

private DateTime? inbetriebnahmedatum;

[DataType(DataType.Date)]
public DateTime? Inbetriebnahmedatum
{
    get { return inbetriebnahmedatum; }
    set { inbetriebnahmedatum = value; OnPropertyChanged(new PropertyChangedEventArgs("Inbetriebnahmedatum")); }
}

View: unchanged

Result: Value not loaded.

Step 3: DisplayFormat added, Datatype removed

Model:

private DateTime? inbetriebnahmedatum;

[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd.MM.yyyy}")]
public DateTime? Inbetriebnahmedatum
{
    get { return inbetriebnahmedatum; }
    set { inbetriebnahmedatum = value; OnPropertyChanged(new PropertyChangedEventArgs("Inbetriebnahmedatum")); }
}

View: unchanged

Result: Date displayed, but no datepicker and Validation Error

Step 4: Addedd ui Culture to Web.config

Web.config

<globalization uiCulture="de-DE" culture="de-DE" />

Result: Same

Step 5: Added Datatype again

Model:

private DateTime? inbetriebnahmedatum;

[DataType(DataType.Date)]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd.MM.yyyy}")]
public DateTime? Inbetriebnahmedatum
{
    get { return inbetriebnahmedatum; }
    set { inbetriebnahmedatum = value; OnPropertyChanged(new PropertyChangedEventArgs("Inbetriebnahmedatum")); }
}

Result: Value not loaded, datepicker shows
