Question

I got a combobox that is populated from a access database. How can I add an item say “all” to the list got from the database and then display it as the first value

Answer 1

After binding it. You can quiet easy do this:

cb.Items.Insert(0,"ALL")

Liked said in the comment. Do this:

Private Sub fview_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 
    Timer1.Enabled = True 
    Timer1.Interval = 1000 
    cenNum.DropDownStyle = ComboBoxStyle.DropDownList 
    cenNum.Items.Insert(0, "All") 'adding all to combo  
   fData() 'function populating the combo from database
    cenNum.SelectedIndex=0 'The new line
end sub
