How to add data for sql to combobox?

this code is working

TextBoxService is a combobox

Dim sql As String
DTS = New DataSet
sql = "SELECT * FROM Service"
dap = New SqlDataAdapter(sql, CON)
dap.Fill(DTS, "Service")
TextBoxService.DataSource = DTS.Tables("Service")
TextBoxService.DisplayMember = "ServiceName"
TextBoxService.ValueMember = "ServiceID"

because I need to at it to 2 comboboxes. it will change both comboboxes when I selectd a combobox.
so i try to use this

bds = New BindingSource
DTS = New DataSet
bds.DataSource = DTS.Tables("Service")
TextBoxService.DataSource = bds
TextBoxService.DisplayMember = "ServiceName"
TextBoxService.ValueMember = "ServiceID"

but it show this error
Cannot bind to the new display member
