DataGridViewComboBox shows a ListView

[DriveU]

My Application : Windows Form Application
Language : C#
I have a DataGridView which I populate with some custom data.
Some of the cells are DropDowns that I populate by EnumTypes
Some need to be populated by Objects which are multicolumn.
On Selection I want to show the MultiColumn Lists for Selection.
Solution
I was thinking on Click of a dropdown I want to show a ListView Is this possible? If it is can anyone show me or point me to a code snippet.
Otherwise I want to show all the columns in the dropdown which should look like columns
this is also acceptable.
Is anyone out here who can help me with this?
Thanks in Advance

I have not tried it my self but this look like what you want.
CodeProject - DataGridView with hierarchical data binding
which is based on this
Customizing the DataGridView to support expanding/collapsing (ala TreeGridView)

All other Googled links I found point to the DataGrid used in ASP.Net or are purchasable controls.

Create a new UserControl, and "put" ListView inside of it. Position the userControl to the position you want (based on the cell (right) mouse click I think).

It might event be possible to create a custom column class that shows the child rows in a ListView (:-/ or event another DataGridView?).
This link shows how to create a custom column class for a calendar control.
