+ * TPageStatePersister uses a private key to generate a private unique hash

+ * By default, the private key is a randomly generated string.
+ * You may specify it explicitly by setting the {@link setPrivateKey PrivateKey} property.
+ * This may be useful if your application is running on a server farm.

+/**
+ * TListControl class
+ *
+ * TListControl is a base class for list controls, such as {@link TListBox},
+ * {@link TDropDownList}, {@link TCheckBoxList}, etc.
+ * It manages the items and their status in a list control.
+ * It also implements how the items can be populated from template and
+ * data source.
+ *
+ * The property {@link getItems} returns a list of the items in the control.
+ * To specify or determine which item is selected, use the
+ * {@link getSelectedIndex SelectedIndex} property that indicates the zero-based
+ * index of the selected item in the item list. You may also use
+ * {@link getSelectedItem SelectedItem} and {@link getSelectedValue SelectedValue}
+ * to get the selected item and its value. For multiple selection lists
+ * (such as {@link TCheckBoxList} and {@link TListBox}), property
+ * {@link getSelectedIndices SelectedIndices} is useful.
+ *
+ * TListControl implements {@link setAutoPostBack AutoPostBack} which allows
+ * a list control to postback the page if the selections of the list items are changed.
+ * The {@link setCausesValidation CausesValidation} and {@link setValidationGroup ValidationGroup}
+ * properties may be used to specify that validation be performed when auto postback occurs.
+ *
+ * There are three ways to populate the items in a list control: from template,
+ * using {@link setDataSource DataSource} and using {@link setDataSourceID DataSourceID}.
+ * The latter two are covered in {@link TDataBoundControl}. To specify items via
+ * template, using the following template syntax:
+ * <code>
+ * &lt;com:TListControl&gt;
+ *   &lt;com:TListItem Value="xxx" Text="yyy" &gt;
+ *   &lt;com:TListItem Value="xxx" Text="yyy" Selected="true" &gt;
+ *   &lt;com:TListItem Value="xxx" Text="yyy" &gt;
+ * &lt;/com:TListControl&gt;
+ * </code>
+ *
+ * When {@link setDataSource DataSource} or {@link setDataSourceID DataSourceID}
+ * is used to populate list items, the {@link setDataTextField DataTextField} and
+ * {@link setDataValueField DataValueField} properties are used to specify which
+ * columns of the data will be used to populate the text and value of the items.
+ * For example, if a data source is as follows,
+ * <code>
+ * $dataSource=array(
+ *    array('name'=>'John', 'age'=>31),
+ *    array('name'=>'Cary', 'age'=>28),
+ *    array('name'=>'Rose', 'age'=>35),
+ * );
+ * </code>
+ * setting {@link setDataTextField DataTextField} and {@link setDataValueField DataValueField}
+ * to 'name' and 'age' will make the first item's text be 'John', value be 31,
+ * the second item's text be 'Cary', value be 28, and so on.
+ * The {@link setDataTextFormatString DataTextFormatString} property may be further
+ * used to format how the item should be displayed. The formatting function is
+ * the sprintf() PHP function.
