not in xaml?

Answer 1

You can use XamlReader.Load

A test with a ListView with 2 columns :

            string sXAML =
                 "<DataTemplate xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\">" +
                " <Grid Height=\"48\" >" +
                "      <Grid.ColumnDefinitions>" +
                "                 <ColumnDefinition Width=\"150\"/>" +
                "                 <ColumnDefinition Width=\"100\"/>" +
                "      </Grid.ColumnDefinitions>" +
                "      <TextBlock Grid.Column=\"0\" VerticalAlignment=\"Center\" Style=\"{ThemeResource BaseTextBlockStyle}\" Text=\"{Binding Name}\" />" +
                "      <TextBlock Grid.Column=\"1\" VerticalAlignment=\"Center\" HorizontalAlignment=\"Left\" Text=\"{Binding Type}\"/>" +
                " </Grid>" +
                "</DataTemplate>";
            var ItemTemplate = (DataTemplate)XamlReader.Load(sXAML);
            lv1.ItemTemplate = ItemTemplate;
            lv1.ItemsSource = files; 

with :

 ObservableCollection<File> files = new ObservableCollection<File>();

 files.Add(new File("File1", "Type1"));
 files.Add(new File("File2", "Type2"));

    public class File
    {
        #region Properties
        public string Name { get; set; }
        public string Type { get; set; }
        #endregion
        public File(string sName, string sType)
        {
            Name = sName;
            Type = sType;           
        }
    }
