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