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 beginCellEdit() method is used to begin the cell editing of the specified jqxTreeGrid when the editable option is set to true. 

Syntax:

$("#treeGrid").jqxTreeGrid('beginCellEdit', rowKey, dataField);

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

  • rowKey: This is the specified row key of the cell that will be started to edit. It also specifies the unique id that identifies the specific row based on id. It is of string type.
  • dataField: This is the specified data field or column name of the cell that will be started to edit. It is of string type.
