public DataTemplate FirstTemplate { get; set; } public DataTemplate SecondTemplate { get; set; } public static readonly DependencyProperty FieldTypeProperty = DependencyProperty.Register("FieldType", typeof(string), typeof(FormFieldTemplateSelector), new PropertyMetadata(string.Empty)); public string F...
