Is there a hidden field in listbox controls?
Im doing an asp application that has a listbox that has data in it. I need to associate a unique ID with the data, but I dont want to show it.
so the listbox data would actually be like:
234  item1
394  item2
907  item3

but the listbox would just show
item1
item2
item3

How could I set this up?
later i will need to access this data by index.

yes, there are separate "text" and "value" properties (as well as "index")
here's a pretty comprehensive tutorial on using the listbox:

Yes, that has how to add items, which I am already doing, but doesnt really cover anything about hidden fields.

        Dim ds As DataSet
        ds = Me._Helper.popKeywords(intId)
        For i As Integer = 0 To ds.Tables(0).Rows.Count - 1
            Me.lbKeywords.Items.Add(ds.Tables(0).Rows(i).Item("term"))
        Next
        ds = Nothing

currently, this is how I add my items, but my terms need to have a "term_id" associated with them in that control, but the "term_id" cant be seen in the listbox.

ds.Tables(0).Rows(i).Item("term_ID")

This solved my problem. Ill give you credit because you mentioned the text and value properties and it got me looking for a value property.

        Dim ds As DataSet
        ds = Me._Helper.popKeywords(intDecisionId)
        For i As Integer = 0 To ds.Tables(0).Rows.Count - 1
            Me.lbKeywords.Items.Add(ds.Tables(0).Rows(i).Item("term"))
            Me.lbKeywords.Items.Item(i).Value = ds.Tables(0).Rows(i).Item("term_id")
        Next
        ds = Nothing
