jQWidgets is a JavaScript framework for making web-based applications for PC and mobile devices. It is a very powerful, optimized, platform-independent, and widely supported framework. The jqxTreeGrid is used for representing data in a tree-like structure. This widget is useful for displaying multi-column of hierarchical data, data paging, sorting and filtering, data editing, column resizing, fixed columns, conditional formatting, aggregates, and rows selection. These widgets also read and display the data from any type of data source such as XML, JSON, Array, CSV, or TSV.

The pagerRenderer property is a callback function and is used in order to personalize the returning of the displayed jqxTreeGrid’s pager. It is of Function type and its default value is null.

Syntax:

  • Set the pagerRenderer property:
$('Selector').jqxTreeGrid({ pagerRenderer: null });  
  • Return the pagerRenderer property:
var pagerRenderer = $('Selector').jqxTreeGrid('pagerRenderer');
