jQWidgets jqxGrid removefilter() 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 removefilter() method is used to remove a filter applied to the displayed jqxGrid. It does not return anything.

Syntax:

$('#Selector').jqxGrid('removefilter', dataField, refreshGrid);

Parameter Values:

  • dataField: It is the stated datafield of the column. It is of type string.
  • refreshGrid: It states whether to refresh the grid or not. It is of type Boolean.
