Hello

I have a little question to a problem I have

I have two listboxes listbox1 and listbox2

listbox1 has a datasource from bindingsource

listbox1.DataSource = dataBS;

and listbox2 is not binded

in listbox1 I have items:

1
2
3
4

i listbox2 I have added manually items
1
2
4


what I want to do is to with listobox2 items filter out listbox1 just to show those items from listbox2


I have tried a foreach statement like this

foreach (object o in listBox2.Items)
                    {
                        DataBS.Filter = ("ID = \'" + (o + "\'"));
                    }

I always get the last item filtered
any help appreciated
