+/**

+ * TPager class.

+ *

+ * TPager creates a pager that controls the paging of the data populated

+ * to a data-bound control specified by {@link setControlToPaginate ControlToPaginate}.

+ * To specify the number of data items displayed on each page, set

+ * the {@link setPageSize PageSize} property, and to specify which

+ * page of data to be displayed, set {@link setCurrentPageIndex CurrentPageIndex}.

+ *

+ * When the size of the original data is too big to be loaded all in the memory,

+ * one can enable custom paging. In custom paging, the total number of data items

+ * is specified manually via {@link setVirtualItemCount VirtualItemCount}, and the data source

+ * only needs to contain the current page of data. To enable custom paging,

+ * set {@link setAllowCustomPaging AllowCustomPaging} to true.

+ *

+ * TPager can be in one of three {@link setMode Mode}:

+ * - NextPrev: a next page and a previous page button are rendered.

+ * - Numeric: a list of page index buttons are rendered.

+ * - List: a dropdown list of page indices are rendered.

+ *

+ * TPager raises an {@link onPageIndexChanged OnPageIndexChanged} event when

+ * the end-user interacts with it and specifies a new page (e.g. clicking

+ * on a page button that leads to a new page.) The new page index may be obtained

+ * from the event parameter's property {@link TPagerPageChangedEventParameter::getNewPageIndex NewPageIndex}.

+ *

+ * When multiple pagers are associated with the same data-bound control,

+ * these pagers will do synchronization among each other so that the interaction

+ * with one pager will automatically update the UI of the other relevant pagers.

+ *

+ * The following example shows a typical usage of TPager:

+ * <code>

+ * $pager->ControlToPaginate="Path.To.Control";

+ * $pager->DataSource=$data;

+ * $pager->dataBind();

+ * </code>

+ * Note, the data is assigned to the pager and dataBind() is invoked against the pager.

+ * Without the pager, one has to set datasource for the target control and call

+ * its dataBind() directly.
