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 getdatainformation() method is used to return the bounded data inputs. It does not has any parameter. It returns an object.

Syntax:

var datainformation = 
    $('#Selector').jqxGrid('getdatainformation');

Returns the number of rows.

var rowscount = datainformation.rowscount;

Returns the sorted information.

var sortinformation = datainformation.sortinformation;

Returns the sorted column.

var sortcolumn = sortinformation.sortcolumn;

Returns the sorted direction.

var sortdirection = sortinformation.sortdirection;

Returns the paging information.

var paginginformation = datainformation.paginginformation;

Returns the page number.

var pagenum = paginginformation.pagenum;

Returns the page size.

var pagesize = paginginformation.pagesize;

Returns the number of pages.

var pagescount = paginginformation.pagescount;
