You can customize the display by* setting {@link setDataFormatString DataFormatString}.** If {@link setReadOnly ReadOnly} is false, TBoundColumn will display cells in edit mode* with textboxes. Otherwise, a static text is displayed.** When a datagrid row is in edit mode, the textbox control in the TBoundColumn* can be accessed by one of the following two methods:* <code>* $datagridItem->BoundColumnID->TextBox* $datagridItem->BoundColumnID->Controls[0]* </code>* The second method is possible because the textbox control created within the* datagrid cell is the first child.** Since v3.1.0, TBoundColumn has introduced two new properties {@link setItemRenderer ItemRenderer}* and {@link setEditItemRenderer EditItemRenderer} which can be used to specify* the layout of the datagrid cells in browsing and editing mode.* A renderer refers to a control class that is to be instantiated as a control.* For more details, see {@link TRepeater} and {@link TDataList}.** @author Qiang Xue <qiang.xue@gmail.com>* @version $Id: TBoundColumn.php 2541 2008-10-21 15:05:13Z qiang.xue $* @package System.Web.UI.WebControls* @since 3.0*/class TBoundColumn extends TDataGridColumn{/*** @return string the class name for the item cell renderer.
