jQWidgets jqxTreeGrid isBindingCompleted() Method

Last Updated : 09 Jan, 2023

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 isBindingCompleted() method is used to check if the binding is accomplished or not. In case, the output is true, then the methods can be called and properties can be set. However, if the output is false and a method is called or the property is set, then the widget will throw an exception. It has no parameters. It returns a Boolean value.

Syntax:

var isCompleted = $("#Selector")
.jqxTreeGrid('isBindingCompleted');
