Creating in Code

Avalonia UI supports creating a data template in code. You can do this by using the FuncDataTemplate<T> class that supports the IDataTemplate interface.

At its simplest you can create a data template by passing a lambda function that creates a control to the FuncDataTemplate<T> constructor, like this:

var template = new FuncDataTemplate<Student>((value, namescope) =>
    new TextBlock
    {
        [!TextBlock.TextProperty] = new Binding("FirstName"),
    });

Which is equivalent to the XAML:

<DataTemplate DataType="{x:Type local:Student}">
    <TextBlock Text="{Binding FirstName}"/>
</DataTemplate>
