在动态创建的WPF数据网格中将自定义模板分配给DateCell

Question

I have been working on this problem for a while and I couldn't figure it out :( I have a datagrid that dynamically filled with data. Sometimes the data is in the form of date/time.

Now, I need to do two things:

1- Delete the time and show only date (eg6/1/2019 12:00:00 AM ---> 6/1/2019)

2- Display datepicker on the cell upon clicking on it.

I googled for solutions and most of solutions are for static datagrid.

I tried resource method but I was not successful.

I appreciate all of your helps

Example of date column in my datagrid:

Something like this, perhaps?

namespace WpfApplication {

    public class Thing
    {
        public string Name { get; set; }
        public DateTime Date { get; set; }
    }

    public partial class MainWindow : Window
    {
        public MainWindow() {
            InitializeComponent();
            DataContext = new Thing[] {new Thing {Name = "A", Date = DateTime.Today}};
        }

        private void DataGrid_AutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e) {
            if (e.PropertyName == "Date")
            {
                var templateColumn = new DataGridTemplateColumn();
                templateColumn.Header = "Date";
                templateColumn.CellTemplate = (DataTemplate) Resources["DateTemplate"];
                templateColumn.CellEditingTemplate = (DataTemplate) Resources["DateEditTemplate"];
                e.Column = templateColumn;
            }
        }
    }
}
