Auto Completing a combo box

ComboBox1.AutoCompleteSource = AutoCompleteSource.ListItems

You can do this through the Properties window for the Combobox too. I used code to make the point more clear. Here’s the complete source code that you could plug into the Load event subroutine for a Form.

   Dim Mary As New List(Of String)
   Dim Words() As String = New String() _
       {"Mary", "Had", "A", "Little", _
       "Lamb.", "It's", "Fleece", _
       "Was", "White", "As", "Snow."}
   Mary.AddRange(Words)
   Mary.Sort()
   ComboBox1.Items.AddRange(Mary.ToArray)
   ComboBox1.DropDownStyle = ComboBoxStyle.DropDownList
   ComboBox1.AutoCompleteSource = AutoCompleteSource.ListItems
   ComboBox1.SelectedIndex = 0
