+ * TRepeater class.
*
- * TRepeater displays its content defined in templates repeatedly based on
- * the given data specified by the {@link setDataSource DataSource} or
- * {@link setDataSourceID DataSourceID} property. The templates can contain
- * static text, controls and special tags.
+ * TRepeater displays its content repeatedly based on the data fetched from
+ * {@link setDataSource DataSource}.
+ * The repeated contents in TRepeater are called items, which are controls and
+ * can be accessed through {@link getItems Items}. When {@link dataBind()} is invoked,
+ * TRepeater creates an item for each row of data and binds the data row to the item.
+ * Optionally, a repeater can have a header, a footer and/or separators between items.
*
- * The {@link setHeaderTemplate HeaderTemplate} property specifies the content
- * template that will be displayed at the beginning, while
- * {@link setFooterTemplate FooterTemplate} at the end.
- * If present, these two templates will only be rendered when the repeater is
- * given non-empty data. In this case, for each data item the content defined
- * by {@link setItemTemplate ItemTemplate} will be generated and displayed once.
- * If {@link setAlternatingItemTemplate AlternatingItemTemplate} is not empty,
- * then the corresponding content will be displayed alternatively with that
- * in {@link setItemTemplate ItemTemplate}. The content in
- * {@link setSeparatorTemplate SeparatorTemplate}, if not empty, will be
- * displayed between items.
+ * The layout of the repeated contents are specified by inline templates.
+ * Repeater items, header, footer, etc. are being instantiated with the corresponding
+ * templates when data is being bound to the repeater.
*
- * Each repeater item has a {@link TRepeaterItem::getItemType type}
- * which tells the position of the item in the repeater. An item in the header
- * of the repeater is of type TListItemType::Header. A body item may be of either
- * TListItemType::Item or TListItemType::AlternatingItem, depending whether the item
- * index is odd or even.
+ * Since v3.1.0, the layout can also be by renderers. A renderer is a control class
+ * that can be instantiated as repeater items, header, etc. A renderer can thus be viewed
+ * as an external template (in fact, it can also be non-templated controls).
*
- * You can retrive the repeated contents by the {@link getItems Items} property.
- * The header and footer items can be accessed by {@link getHeader Header}
- * and {@link getFooter Footer} properties, respectively.
+ * A renderer can be any control class.
+ * -If the class implements {@link IDataRenderer}, the <b>Data</b>
+ * property will be set as the data row during databinding. Many PRADO controls
+ * implement this interface, such as {@link TLabel}, {@link TTextBox}, etc.
+ * - If the class implements {@link IItemDataRenderer}, the <b>ItemIndex</b> property will be set
+ * as the zero-based index of the item in the repeater item collection, and
+ * the <b>ItemType</b> property as the item's type (such as TListItemType::Item).
+ * {@link TRepeaterItemRenderer} may be used as the convenient base class which
+ * already implements {@link IDataItemRenderer}.
*
- * When TRepeater creates an item, it will raise an {@link onItemCreated OnItemCreated}
- * so that you may customize the newly created item.
- * When databinding is performed by TRepeater, for each item once it has finished
- * databinding, an {@link onItemDataBound OnItemDataBound} event will be raised.
+ * The following properties are used to specify different types of template and renderer
+ * for a repeater:
+ * - {@link setItemTemplate ItemTemplate}, {@link setItemRenderer ItemRenderer}:
+ * for each repeated row of data
+ * - {@link setAlternatingItemTemplate AlternatingItemTemplate}, {@link setAlternatingItemRenderer AlternatingItemRenderer}:
+ * for each alternating row of data. If not set, {@link setItemTemplate ItemTemplate} or {@link setItemRenderer ItemRenderer}
+ * will be used instead.
+ * - {@link setHeaderTemplate HeaderTemplate}, {@link setHeaderRenderer HeaderRenderer}:
+ * for the repeater header.
+ * - {@link setFooterTemplate FooterTemplate}, {@link setFooterRenderer FooterRenderer}:
+ * for the repeater footer.
+ * - {@link setSeparatorTemplate SeparatorTemplate}, {@link setSeparatorRenderer SeparatorRenderer}:
+ * for content to be displayed between items.
+ * - {@link setEmptyTemplate EmptyTemplate}, {@link setEmptyRenderer EmptyRenderer}:
+ * used when data bound to the repeater is empty.
+ *
+ * If a content type is defined with both a template and a renderer, the latter takes precedence.
+ *
+ * When {@link dataBind()} is being called, TRepeater undergoes the following lifecycles for each row of data:
+ * - create item based on templates or renderers
+ * - set the row of data to the item
+ * - raise {@link onItemCreated OnItemCreated}:
+ * - add the item as a child control
+ * - call dataBind() of the item
+ * - raise {@link onItemDataBound OnItemDataBound}:
*
* TRepeater raises an {@link onItemCommand OnItemCommand} whenever a button control
* within some repeater item raises a <b>OnCommand</b> event. Therefore,
* you can handle all sorts of <b>OnCommand</b> event in a central place by
* writing an event handler for {@link onItemCommand OnItemCommand}.
*
- * Note, the data bound to the repeater are reset to null after databinding.
- * There are several ways to access the data associated with a repeater item:
- * - Access the data in {@link onItemDataBound OnItemDataBound} event
+ * When a page containing a repeater is post back, the repeater will restore automatically
+ * all its contents, including items, header, footer and separators.
+ * However, the data row associated with each item will not be recovered and become null.
+ * To access the data, use one of the following ways:
* - Use {@link getDataKeys DataKeys} to obtain the data key associated with
* the specified repeater item and use the key to fetch the corresponding data
* from some persistent storage such as DB.
- * - Save the data in viewstate and get it back during postbacks.
+ * - Save the whole dataset in viewstate, which will restore the dataset automatically upon postback.
+ * Be aware though, if the size of your dataset is big, your page size will become big. Some
+ * complex data may also have serializing problem if saved in viewstate.
