DataBinding DataGridView List of Lists c# complex Collections

I'm trying to bind a list of page classes to a datagridview. 

class Page : INotifyPropertyChanged
{
    public List<Tuple<DateTime, String>> Lines { get; set; }
    public Color c { get; set; }
    public String filePath { get; set; }

//rest of class code...
}
//on the 'Form1' class
BindingList<Page> pages = new BindingList<Page>();

I want one row in the datagridview to represent a row in the list

List<Tuple<DateTime, String>> Lines

With one column for the DateTime and one for the corresponding string.

Each row should be color coordinated to the page with which it belongs.

I'm trying to bind it because I want the GUI to be updated live with updates to source files.

My implementations have been going round in circles for days, any help/advice would be greatly appreciated. Thanks!

edit: some sample data:

20-Apr-11 08:36:44.312   Start       I *** C:\Cromos 3.0\toolset\Ntbin\Release\crm_gui_gtm.exe on BENJAMIN-PC - release - cromos: build 2780, Gui version: 400, File version: 80 ***
20-Apr-11 08:36:44.312   symbol element total: 9

For anyone viewing this question, I fixed the problem by changing my data structure. I created a class for a single line like so:

    class Line : INotifyPropertyChanged
{
    public Color _c;
    public DateTime _dateTime;
    public String _comment;
    public event PropertyChangedEventHandler PropertyChanged;
}

then implemented a BindingList to store all the lines and followed the example Vikram linked.

        BindingList<Line> all = new BindingList<Line>();

also, make sure you include this line in the form intialiser and not a method as I did!

            dataGridView1.DataSource = all;
