Question

I need to create a DataGridColumn from code.
The XAML equivalent would be:

    <data:DataGridTemplateColumn Header="Name" Width="100">
        <data:DataGridTemplateColumn.CellTemplate>
            <DataTemplate>
                <TextBlock Text="{Binding Name}" TextTrimming="WordEllipsis"></TextBlock>
            </DataTemplate>
        </data:DataGridTemplateColumn.CellTemplate>
    </data:DataGridTemplateColumn>

I’ve started like that:

 DataGridTemplateColumn column = new DataGridTemplateColumn
   {
      Header = "Name",
      Width = 100,
   };

TextBlock inside =  new TextBlock {TextTrimming = TextTrimming.CharacterEllipsis};

But I don’t know how to ‘merge’ such puzzles. There are nested elements in XAML, how to achieve this from code?

A good way to do this is to pack the entire XAML snippet into a string and call XamlReader.Load() or XamlReader.Parse() on it. The bonus feature of this approach is that it’ll work in Silverlight as well (with some fiddling), where you can’t build DataTemplates in code.
