Complex DataGrid Binding

[Dave]

The question I have is how to -=> Effectively <=- and -=> Efficently <=-
bind a DataGrid to a 1 deep organizational chart, where "R" would be a
row of data and 1..N would be the columns of the row. I need to have the
data displayed and updated/added, so I will need 2 way binding.
+---+
| R | (View this in NotePad)
+---+
|
+-------+-------+-------+-------+
| | | | |
+---+ +---+ +---+ +---+ +---+
| 1 | | 2 | | 3 | |...| | N |
+---+ +---+ +---+ +---+ +---+
I am currently creating the columns of the DataGrid dynamically, which
works fine. The binding is where I am getting stuck. A -=> Very <=-
simplistic view of my data looks like this.

+-----------------------------+
| MyRowCollection |
+-----------------------------+
| Guid ID |
| MyRowCollection rows |
+-----------------------------+
| 1
| to
| N
+-----------------------------+
| MyRow |
+-----------------------------+
| Guid ID |
| MyColumnDataCollection data |
+-----------------------------+
| 1
| to
| N
+------------------+
| MyColumnData |
+------------------+
| Guid ID |
| object data |
+------------------+

Any thoughts would be appreciated.
