Binding DataGridTemplateColumn
I'm not completely sure what you're trying to do but if you need to get the DataContext of the whole row, you can use a RelativeSource binding to walk up the visual tree. Like so:
<DataTemplate x:Key="DoubleField"> <StackPanel> <TextBlock Text="{Binding DataContext.Value1, RelativeSource={RelativeSource AncestorType=DataGridRow}}"/> <TextBlock Text="{Binding DataContext.Value2, RelativeSource={RelativeSource AncestorType=DataGridRow}}"/> </StackPanel></DataTemplate>
