Databinding the DataGrid column header in code

Question

How do I databind a WPF Toolkit DataGrid column header value in code (not XAML)?

DataGridColumn fooColumn =  new DataGridTextColumn 
{
  Header = "Foo",
  Binding = new Binding {Path = new PropertyPath("BindingPath"), 
                         Mode = BindingMode.OneWay}
};

This databinds the content of the cells of the column. But how do I databind the header text ("Foo") itself (to, say, a string property on a viewmodel)?

Answer 1

DataGridColumn fooColumn =  new DataGridTextColumn 
{
  Binding = new Binding {Path = new PropertyPath("BindingPath"), 
                         Mode = BindingMode.OneWay}
};

BindingOperations.SetBinding(fooColumn, DataGridColumn.HeaderProperty, new Binding("Foo") { Source = yourViewModel} );

Answer 2

Looks like Header is a Dependancy Property in the lastest build
