Wpf - How to build a DataTemplate in c# code?

To build a DataTemplate in C# code, you can create the necessary elements programmatically and set their properties accordingly. Here's an example of how you can create a DataTemplate for displaying items in a ListBox:

using System.Windows; using System.Windows.Controls; using System.Windows.Media; namespace WpfApp { public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); // Create a DataTemplate DataTemplate dataTemplate = new DataTemplate(typeof(string)); // Create a TextBlock to display the data FrameworkElementFactory textBlockFactory = new FrameworkElementFactory(typeof(TextBlock)); textBlockFactory.SetBinding(TextBlock.TextProperty, new System.Windows.Data.Binding()); // Set properties for the TextBlock textBlockFactory.SetValue(TextBlock.ForegroundProperty, Brushes.Red); textBlockFactory.SetValue(TextBlock.FontSizeProperty, 14.0); // Set the VisualTree of the DataTemplate to the TextBlock dataTemplate.VisualTree = textBlockFactory; // Apply the DataTemplate to the ListBox listBox.ItemTemplate = dataTemplate; // Add items to the ListBox listBox.Items.Add("Item 1"); listBox.Items.Add("Item 2"); listBox.Items.Add("Item 3"); } } }

In this example:

  • We create a DataTemplate instance using the constructor that takes the type of the data objects that the template will display (in this case, strings).
  • We create a FrameworkElementFactory for a TextBlock element, which will display the data.
  • We set a binding on the Text property of the TextBlock to bind it to the data item.
  • We set additional properties for the TextBlock, such as Foreground color and FontSize.
  • We set the VisualTree property of the DataTemplate to the TextBlock factory.
  • Finally, we apply the DataTemplate to a ListBox named listBox and add items to the ListBox.

This approach allows you to dynamically create DataTemplates in C# code and customize them as needed.
