This is the easy way to bind the DataGridTextColumn header to the data context: <DataGrid x:Name=”summaryGrid” Grid.Row=”3″ AutoGenerateColumns=”False” IsReadOnly=”True” CanUserAddRows=”False”> <DataGrid.Columns> <DataGridTextColumn Header=”Hard Coded Title” Width=”*”/> <DataGridTextColumn Width=”100″> <DataGridTextColumn.Header> <TextBlock Text=”{Binding DataContext.SecondColumnTitle, RelativeSource={RelativeSource AncestorType={x:Type local:MainWindow}}}”/> </DataGridTextColumn.Header> </DataGridTextColumn> <DataGridTextColumn Width=”150″> <DataGridTextColumn.Header> <TextBlock Text=”{Binding DataContext.ThirdColumnTitle, RelativeSource={RelativeSource AncestorType={x:Type local:MainWindow}}}”/> </DataGridTextColumn.Header> </DataGridTextColumn> </DataGrid.Columns> </DataGrid> You will obviously need to … Read more
