<h1>List Controls</h1>
<p>
List controls covered in this section all inherit directly or indirectly from <tt>TListControl</tt>. Therefore, they share the same set of commonly used properties, including,
<ul>
<li><tt>Items</tt> - list of items in the control. The items are of type <tt>TListItem</tt>. The item list can be populated via databinding or specified in templates like the following:
<com:TTextHighlighter Language="prado" CssClass="source">
&lt;com:TListBox&gt;
  &lt;com:TListItem Text="text 1" Value="value 1" /&gt;
  &lt;com:TListItem Text="text 2" Value="value 2" Selected="true" /&gt;
  &lt;com:TListItem Text="text 3" Value="value 3" /&gt;
&lt;/com:TListBox&gt;
</com:TTextHighlighter>
</li>
<li><tt>SelectedIndex</tt> - the zero-based index of the first selected item in the item list.</li>
<li><tt>SelectedIndices</tt> - the indices of all selected items.</li>
<li><tt>SelectedItem</tt> - the first selected item in the item list.</li>
<li><tt>SelectedValue</tt> - the value of the first selected item in the item list.</li>
<li><tt>AutoPostBack</tt> - whether changing the selection of the control should trigger postback.</li>
<li><tt>CausesValidation</tt> - whether validation should be performed when postback is triggered by the list control.</li>
</ul>
</p>
<p>
Since <tt>TListControl</tt> inherits from <tt>TDataBoundControl</tt>, these list controls also share a common operation known as <tt>databinding</tt>. The data to be bound can be specified via either <tt>DataSource</tt> or <tt>DataSourceID</tt>. More details about databinding are covered in later chapters of this tutorial.

<h2>TListBox</h2>
<p>
<tt>TListBox</tt> displays a list box that allows single or multiple selection. Set the property <tt>SelectionMode</tt> as <tt>Single</tt> to make a single selection list box, and <tt>Multiple</tt> a multiple selection list box. The items in the list box are represented by the <tt>Items</tt> property. The number of rows displayed in the box is specified via the <tt>Rows</tt> property value.

<h2>TDropDownList</h2>
<p>
<tt>TDropDownList</tt> displays a dropdown list box that allows users to select a single option from a few prespecified ones. The items in the list box are represented by the <tt>Items</tt> property. The selected item can be retrieved via <tt>SelectedItem</tt> property. If <tt>AutoPostBack</tt> is true, selection change will cause page postback.
