WPF datagrid header text binding

by

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 have properties: SecondColumnTitle and ThirdColumnTitle implemented on your data context class.

I have this solution working in .net 4.5 and did not have a chance nor reason to try it in earlier versions of the framework.
