Dim oDB As New Utilitarios
Dim SqlString = "Select * From provincia where codigo_provincia= '" & CboProvincia.SelectedItem.ToString & "'" _
& " and codigo_zona='000' and codigo_ciudad <> '000' " _
& " order by codigo_provincia,codigo_ciudad "
Me.cboCiudad.DataSource = oDB.GetDataTable(SqlString, CommandType.Text)

Me.cboCiudad.DataTextField = "descripcion"
Me.cboCiudad.DataValueField = "id"
Me.cboCiudad.DataBind()
Me.DataBind()
End Sub

Did you bind the CboProvincia? not sure but try.
CboProvincia.SelectedValue.ToString
