jQWidgets jqxGrid refreshfilterrow() Method

Last Updated : 29 Mar, 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 jqxGrid is used to illustrate a jQuery widget that shows data in tabular form. Moreover, it renders full support for connecting with data, as well as paging, grouping, sorting, filtering, and editing.

The refreshfilterrow() method is used to refresh the filter row as well as upgrade the widgets of the filter in the displayed jqxGrid. Moreover, the widgets of the filter row coexisted along with the filter available. It has no parameters and does not return anything.

Syntax:

$('#Selector').jqxGrid('refreshfilterrow');
