Problem using datasource with a combobox in a ToolstripDropdownButton

[CNSZU]

Hello all,

Does anyone know how to attach a datasource to a combobox that resides in a toolstripdropdo wnbutton?

With fMain.ToolStripComboBox1.ComboBox
            .DataSource = dv
            .DisplayMember = "City"
            .ValueMember = "ID"
End With

I have confirmed that this code works with a combobox in a toolstrip, however.
Is this a bug in .Net? Can anyone else confirm this?
