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 sources such as XML, JSON, Array, CSV, or TSV.

The sortBy() method is used to sort a column of the specified jqxTreeGrid. The sortable is set to true.

Syntax:

$("Selector").jqxTreeGrid('sortBy', dataField, sortOrder);

Parameters: This method accepts two parameters that are illustrated below:

  • dataField: This is the specified data field column that is going to be sorted.
  • sortOrder: This is the specified sorting order. Its possible values are ‘asc‘, ‘desc‘, or null.

Return Values: This method does not return any values.
