For what it's worth:
If you needed to change the contents of the combobox in response to an event (such as the user making a selection in another combobox). You should use update panels (or javascript...).

Such (html) code would look like:

<asp:ScriptManager ID="ScriptManager1" runat="server">
        </asp:ScriptManager>
    
        <asp:UpdatePanel ID="UpdatePanel1" runat="server">
        <ContentTemplate>
        'Your combobox here
        </ContentTemplate>
        </asp:UpdatePanel>

The script manager is there to handle Ajax controls since they cannot work without one (and update panels are Ajax). The update panel needs the content template tags so that it knows which controls are inside of it.

Again I realize you've solved this issue, but hopefully this will help someone in the future.

Try using DataSource property to bind the data with the contorol:

Dim listofdays As New List(Of String)()
'populate the list
'then bind comboBox with the generic list<T>:
comboBox1.DataSource = listofdays
