How to display progressbar in datagridview

Hi experts

i bind a datagridview with a bindinglist(of Object)

the object contains a progressbar :

public class theObj

private _pb as progressbar

public sub new
_pb = new progressbar
end sub

public readonly property MyProgressBar as progressbar
get
return _pb
end get
end property

end class

the binding works but the datagridview use the "tostring" method of the progress bar that's why i see "system.windows.forms.progressbar"

how can i display the progress bar properly WITHOUT telling the datagridview that such column is a progress bar?

is it possible?

Thank you,

Regards.
