sortBy is not stable

[GSerjoParticipant]

Could you please clarify why executing several times xjgw.sortBy($grid, sortColumn, xjgh.outOfSortDirection(sortInformation.sortdirection)) change line order for lines with the same cell values? Looks like sortBy is not stable.

For instance, we have a grid, after executing xjgw.sortBy($grid, sortColumn, xjgh.outOfSortDirection(sortInformation.sortdirection)) twise (sort by A) lines with 10 values change there position.

A | B
—–
10| F
10| B
14| D
3 | K

Could you please suggest how to make it stable.

Hi GSerjo,

I don’t know what that function is. Such code is definitely not part of our package.

Hi Peter,

it presents in the api (search by sortby) this one http://www.jqwidgets.com/jquery-widgets-documentation/documentation/jqxgrid/jquery-grid-api.htm

here’s the signature.

$('#jqxGrid').jqxGrid('sortby', 'columndatafield', 'asc');

P.S. sorry in the question above was code on typescript

as a result following method is called

export function sortBy(grid: JQuery, column: string, direction: string) {
    asBanned(grid).jqxGrid('sortby', column, direction);
}

Hi GSerjo,

I know how it is in the API, but the way you call it is incorrect i,e xjgw.sortBy($, should be $(“#someID”).jqxGrid(‘sortby’,…. Also sorting is by single column value and other columns do not play any role in the sorting. If you wish, you may implement your own sorting function based on custom criteria as shown in the custom sorting example on our Grid demos page.

Peter, thanks for the quick reply.

Is there any way to create another grid based on the previous one and save sorting? (i.e. resort new grid as the previous one).

I got the getsortinformation and applied it, sorted by column. Is there any way to apply full sortinformation without sorting by column?

Hi GSerjo,

We do not have such built in method in our Grid unfortunately.
