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 rendergridrows property is a callback function that is called when the rows of the displayed jqxGrid is rendered. In simple words, when the grid is utilized in the virtual mode, then the function will be called that should return an array of rows, which are rendered by the grid. It is of function type and its by default value is null.
Syntax:
- Set the rendergridrows property:
$('Selector').jqxGrid({ rendergridrows: null });- Return the rendergridrows property:
var rendergridrows = $('Selector').jqxGrid('rendergridrows');Linked Files: Download jQWidgets from the given link. In the HTML file, locate the script files in the downloaded folder.
