How to get selectedItem in DatagridviewComboBoxCell

[Guest]

I have a DatagridviewComboBoxCell with self added object (with an id and a
string field) as items to the DatagridviewComboBoxCell.

Dim cboCell As New DataGridViewComboBoxCell
cboCell.Items.Add(new MyObj(1,"Item 1"))
cboCell.Items.Add(new MyObj(2,"Item 2"))
cboCell.Items.Add(new MyObj(3,"Item 3"))

But I cannot find a method from DataGridViewComboBoxCell
to get back the selected MyObj in the cboCell list.
I suppose there should be a selectedItem property as in a comboBox control
but it doesn't have.

Please help !!!

I've solve the get selectedItem by the approach in
http://msdn2.microsoft.com/en-us/library/ms404353.aspx

But another problem is cannot set a selected item for
DatagridviewComboBoxCell.
I can only set the value (displayed) for DatagridviewComboBoxCell, but
cannot not
set my predefined item (id, string) in the DatagridviewComboBoxCell.
