DataGrid and DataGridTabelStyle

[Gilgamesh]

Hello there,

I've got a DataGrid, on a Windows form, which is using a DataGridTableStyle
to selectively display columns from a Collection. In other words, the grid's
data source is set to a collection. The grid is set for ReadOnly because I
don't want it to update the collection. The problem is that when the Grid is
a bout to lose focus, it throws an error saying that the index was out of
range when trying to commit to the datasource. How can I fix this problem?

Thanks,
Gilgamesh
