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 goToPage() method is used to navigate to a specified page of jqxTreeGrid. This method works when the pageable property is set to true.
Syntax:
$("#treeGrid").jqxTreeGrid('goToPage', pageIndex);Parameters: This method accepts a parameter that is illustrated below.
- pageIndex: This is the specified page index on which navigation will be done. Its value starts from 0.
Return Values: This method does not return any values.
