In the DataGrid PreparingCellForEdit event cast the EditElement to a textbox and set it IsReadOnly to true when you do not want the user to be able to edit the cell

http://msdn.microsoft.com/en-us/library/system.windows.controls.datagrid.preparingcellforedit(VS.95).aspx

    Private Sub dgProducts_PreparingCellForEdit(ByVal sender As Object, ByVal e As System.Windows.Controls.DataGridPreparingCellForEditEventArgs) Handles dgProducts.PreparingCellForEdit
        If DirectCast(dgProducts.SelectedItem, Northwind.Products).ProductName.StartsWith("C") Then
            DirectCast(e.EditingElement, TextBox).IsReadOnly = True
        End If

    End Sub

Is it not just worth assigning the IsReadOnly property to true in your XAML on the columns that you don't want users to edit?
