Clear a Combo Box filled previously with a Data Source

Question

I filled a combo box with a DataSource, everything works as intended but now I need clear each combo box. I cant use ComboBox.Items.Clear, since I get a error saying I cant modify a item collection when a DataSource property is established (translated)

ComboBox.Items.Clear Loop based on items.Count and remove x items

This is how I filled the combo box!

 Dim tabla_escenario_busqueda As New DataTable

        tabla_escenario_busqueda = Capa_de_Logica.BuscarInfoPP(txt_id_requerimiento_escenario_ver.Text) 'Llenar el combo Box
        txt_num_escenario_escenario_ver.DataSource = tabla_escenario_busqueda   'Se llena el combo box
        txt_num_escenario_escenario_ver.DisplayMember = "numero_escenario"
        'Fuente: https://stackoverflow.com/questions/17729770/how-do-i-bind-data-source-to-a-combobox

Or set the DataSurce to null: `DataSource = Nothing`. Also, dispose of it if it's still alive. — Jimi, Mar 27 '19 at 23:02
