Answer 1

You can do it by binding TextBlock.Text and you can do it either for all column headers in a DataGrid by changing ContentTemplate of header to be your custom TextBlock and then just set Header to text you want to display. It will also apply to automatically generated columns

<DataGrid ...>
   <DataGrid.Resources>
      <Style TargetType="{x:Type DataGridColumnHeader}">
         <Setter Property="ContentTemplate">
            <Setter.Value>
               <DataTemplate>
                  <TextBlock Text="{Binding}" TextWrapping="Wrap"/>
               </DataTemplate>
            </Setter.Value>
         </Setter>
      </Style>
   </DataGrid.Resources>
   <DataGrid.Columns>
      <DataGridTextColumn Binding="{Binding Name}" Header="Header Text">
   </DataGrid.Columns>
</DataGrid>       

or can also do it per column just change TextBlock.Text in you header template to use binding, as above

<TextBlock Text="{Binding}" TextWrapping="Wrap"/>

and then you column could look like this:

<DataGridTextColumn 
    Binding="{Binding Name}" 
    HeaderTemplate="{StaticResource ColumnHeaderTemplate}"
    Header="Header Text"/>
