Custom sort function

[antonomaseParticipant]

Hi,

In a jqxGrid, is it possible to have a custom sort function on a column ?
Something like that :

$("#jqxGrid").jqxGrid(
{
 columns: [
  {...
  {text: 'label', datafield: 'label', sortmode: function (val1, val2) {
       if (some non standard sort condition on val1 and val2) return true else return false;
     }
  }
]}

Best regards

Hi antonomase,

Yes, this functionality is achievable with jqxGrid component and we have documentation and demos for it.

Link to the documentation: https://www.jqwidgets.com/jquery-widgets-documentation/documentation/jqxgrid/jquery-grid-sorting.htm
Link to the demo: https://www.jqwidgets.com/jquery-widgets-demo/demos/jqxgrid/customsorting.htm?ui-start

Hi Yavor,

Thanks for the answer

I added some lines to answer my need : sort dates in dd/mm/yyyy format but in a textBox field and not a dateTimeInput field

  $(document).ready(function () {
            // prepare the data
            var data = generatedata(20);
            var sortcolumn;

            var customsortfunc = function (column, direction) {
                var sortdata = new Array();
                //Store the current sort column
                sortcolumn = column;
    ...
            var compare = function (value1, value2) {
                if (sortcolumn === 'textDate') {
                    //Reverse dd/mm/yyyy to yyyymmdd
                    tmpvalue1 = String(value1).substr(-4)+String(value1).substr(3,2)+String(value1).substr(0,2);
                    tmpvalue2 = String(value2).substr(-4)+String(value2).substr(3,2)+String(value2).substr(0,2);
                    value1 = tmpvalue1;
                    value2 = tmpvalue2;
                }
    ...
 

This meets the need, but it is not very elegant. A callback function associated to the sorting on the column would be more consistent with the other behaviors on this column (renderer, filter,…).
