/**
 * TPager class.
 *
 * TPager creates a pager that provides UI for end-users to interactively
 * specify which page of data to be rendered in a {@link TDataBoundControl}-derived control,
 * such as {@link TDataList}, {@link TRepeater}, {@link TCheckBoxList}, etc.
 * The target data-bound control is specified by {@link setControlToPaginate ControlToPaginate},
 * which must be the ID path of the target control reaching from the pager's
 * naming container. Note, the target control must have its {@link TDataBoundControl::setAllowPaging AllowPaging}
 * set to true.
 *
 * TPager can display three different UIs, specified via {@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.
 *
 * When the pager mode is either NextPrev or Numeric, the paging buttons may be displayed
 * in three types by setting {@link setButtonType ButtonType}:
 * - LinkButton: a hyperlink button
 * - PushButton: a normal button
 * - ImageButton: an image button (please set XXXPageImageUrl properties accordingly to specify the button images.)
 *
 * Since Prado 3.2.1, you can use the {@link setButtonCssClass ButtonCssClass} property to specify a css class
 * that will be applied to each button created by the pager in NextPrev or Numeric mode.
 *
 * 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}.
 * Normally, in the event handler, one can set the {@link TDataBoundControl::getCurrentPageIndex CurrentPageIndex}
 * to this new page index so that the new page of data is rendered.
 *
 * Multiple pagers can be associated with the same data-bound control.
 *
