+ * - {@link TActiveBoundColumn}, the active counterpart to {@link TBoundColumn}.
+ * - {@link TActiveEditCommandColumn}, the active counterpart to {@link TEditCommandColumn}.

+/**
+ * TActiveTableRow class.
+ *
+ * TActiveTableRow is the active counterpart to the original {@link TTableRow} control
+ * and displays a table row. The table cells in the row can be accessed
+ * via {@link getCells Cells}. The horizontal and vertical alignments of the row
+ * are specified via {@link setHorizontalAlign HorizontalAlign} and
+ * {@link setVerticalAlign VerticalAlign} properties, respectively.
+ *
+ * TActiveTableRow allows the contents of the table row to be changed during callback. When
+ * {@link onRowSelected RowSelected} property is set, selecting (clicking on) the row will
+ * perform a callback request causing {@link onRowSelected OnRowSelected} event to be fired.
+ *
+ * It will also respond to a bubbled {@link onCellSelected OnCellSelected} event of a
+ * {@link TActiveTableCell} child control and fire a {@link onRowSelected OnRowSelected} event.
+ *
+ * TActiveTableRow allows the client-side row contents to be updated during a
+ * callback response by getting a new writer, invoking the render method and flushing the
+ * output, similar to a {@link TActivePanel} control.
+ * <code>
+ * function callback_request($sender, $param)
+ * {
+ *     $this->active_row->render($param->getNewWriter());
+ * }
+ * </code>
+ *
+ * Please refer to the original documentation of the regular counterpart for usage.
