<div class="markdown level1 remarks"><p>
      Use the <b>AutoCompleteCustomSource</b>, <span class="xref">GrapeCity.Win.Spread.InputMan.CellType.GcTextBox.AutoCompleteMode</span>,
      and <b>AutoCompleteSource</b> properties to create a <span class="xref">GrapeCity.Win.Spread.InputMan.CellType.GcTextBox</span>
      that automatically completes the input string by comparing the prefix being entered to the
      prefixes of all strings in a maintained source. This is useful for TextBox controls in which
      URLs, addresses, file names, or commands are frequently entered.
    <p></p><p>
      The use of the <b>AutoCompleteCustomSource</b> property is optional, but you must
      set the <b>AutoCompleteSource</b> property to CustomSource in order to use
    <b>AutoCompleteCustomSource</b>.
    </p><p></p><p>
      You must use the <b>AutoCompleteMode</b> and <b>AutoCompleteSource</b>
      properties together.
