/**
 * TDropDownListColumn class
 *
 * TDropDownListColumn represents a column that is bound to a field in a data source.
 * The cells in the column will be displayed using the data indexed by
 * {@link setDataTextField DataTextField}. You can customize the display by
 * setting {@link setDataTextFormatString DataTextFormatString}.
 *
 * If {@link setReadOnly ReadOnly} is false, TDropDownListColumn will display cells in edit mode
 * with dropdown lists. Otherwise, a static text is displayed.
 * The currently selected dropndown list item is specified by the data indexed with
 * {@link setDataValueField DataValueField}.
 *
 * There are two approaches to specify the list items available for selection.
 * The first approach uses template syntax as follows,
 * <code>
 *   <com:TDropDownListColumn ....>
 *     <com:TListItem Value="1" Text="first item" />
 *     <com:TListItem Value="2" Text="second item" />
 *     <com:TListItem Value="3" Text="third item" />
 *   </com:TDropDownListColumn>
 * </code>
 * The second approach specifies a data source to be bound to the dropdown lists
 * by setting {@link setListDataSource ListDataSource}. Like generic list controls,
 * you may also want to specify which data fields are used for item values and texts
 * by setting {@link setListValueField ListValueField} and
 * {@link setListTextField ListTextField}, respectively.
 * Furthermore, the item texts may be formatted by using {@link setListTextFormatString ListTextFormatString}.
 * Note, if you specify {@link setListDataSource ListDataSource}, do it before
 * calling the datagrid's dataBind().
 *
 * The dropdown list control in the TDropDownListColumn can be accessed by one of
 * the following two methods:
 * <code>
 * $datagridItem->DropDownListColumnID->DropDownList
 * $datagridItem->DropDownListColumnID->Controls[0]
 * </code>
 * The second method is possible because the dropdown list control created within the
 * datagrid cell is the first child.
