Question

I am trying to create a generic view, and I want it to contain a ListBox with a datatemplate

I want to create it either using pure C# code or if possible load it through xaml? If I can create a template I can get in c# as a resource of sorts.

What I have made until now is

        private static ListBox CreateDayListBox()
    {
        var listBox = new ListBox();
        var dataTemplate = new DataTemplate();

        var grid = new Grid();
        var columnDefinition1 = new ColumnDefinition {Width = GridLength.Auto};
        var columnDefinition2 = new ColumnDefinition();

        grid.ColumnDefinitions.Add(columnDefinition1);
        grid.ColumnDefinitions.Add(columnDefinition2);

        var rectangleItemBought = new Rectangle {Width = 50, Height = 50};
        rectangleItemBought.SetBinding(Rectangle.FillProperty, new Binding("Bought"));
        grid.Children.Add(rectangleItemBought);

        var textBlockItemName = new TextBlock();
        textBlockItemName.SetBinding(TextBlock.TextProperty, new Binding("Name"));
        var textBlockItemQuantity = new TextBlock();
        textBlockItemQuantity.SetBinding(TextBlock.TextProperty, new Binding("Quantity"));
        var textBlockItemQuantityType = new TextBlock();
        textBlockItemQuantityType.SetBinding(TextBlock.TextProperty, new Binding("QuantityType"));

        var stackpanel = new StackPanel();
        Grid.SetColumn(stackpanel, 1);
        stackpanel.Children.Add(textBlockItemName);
        stackpanel.Children.Add(textBlockItemQuantity);
        stackpanel.Children.Add(textBlockItemQuantityType);
        grid.Children.Add(stackpanel);

        return listBox;
    }

So I want the listbox datatemplate to contain 1 rectangle, 1 stackpanel with 3 textboxes inside

You can write the template in XAML then load it in your code.

Read this.

Besides, I’m pretty sure you can create the DataTemplate by code the same way you created the controls, look at this code (credit):

DataTemplate template = new DataTemplate();
FrameworkElementFactory factory =
  new FrameworkElementFactory(typeof(StackPanel));
template.VisualTree = factory;
FrameworkElementFactory childFactory =
  new FrameworkElementFactory(typeof(Image));
childFactory.SetBinding(Image.SourceProperty, new Binding("Machine.Thumbnail"));
childFactory.SetValue(Image.WidthProperty, 170.0);    
childFactory.SetValue(Image.HeightProperty, 170.0);
factory.AppendChild(childFactory);
childFactory = new FrameworkElementFactory(typeof(Label));
childFactory.SetBinding(Label.ContentProperty,
  new Binding("Machine.Descriiption"));
childFactory.SetValue(Label.WidthProperty, 170.0);
childFactory.SetValue(Label.HorizontalAlignmentProperty,
  HorizontalAlignment.Center);
factory.AppendChild(childFactory);
