Calling sort on slickgrid

Question

In the slickgrid I\'m able to set the sort column and it\'s sort direction using the grid.SetSortColumn(colName,true/false). This only sets the sorting glyph but do

Answer 1

I'm using multicolumn sorting, and loading saved sort data when initialising the grid.

As expected, setSortColumns set the sorting, but didnt actually apply it, and dataView.reSort() or .fastSort() didnt seem to help, regardless of what point in loading I called them (I must have missed something, but just couldnt get it to work).

In the end, this worked for me. I call it immediately after populating my dataView from an ajax call. Its probably not the slickest, so happy to take feedback on board!

function forceResort() {

    var sortColumns = grid.getSortColumns();
    var cols = [];
    $.each(sortColumns, function(index, value) {
        var columnId = value.columnId;
        var sortAsc = value.sortAsc;
        var sortCol = { field: columnId };
        var col = { sortCol: sortCol, sortAsc : sortAsc};
        cols.push(col);
    });

    dataView.sort(function (dataRow1, dataRow2) {

        var sortResult = 0;
        for (var i = 0, l = cols.length; i < l; i++) {
            if (sortResult !== 0) {
                break;
            }

            var field = cols[i].sortCol.field;
            var sign = cols[i].sortAsc ? 1 : -1;
            var value1 = dataRow1[field] || ''; //handle nulls - otherwise erratic sorting
            var value2 = dataRow2[field] || ''; //handle nulls - otherwise erratic sorting

            if ($.inArray(field, dateTypeColumns) > -1) {
                sortResult = compareDates(value1, value2) * sign;
            } else {
                if ($.inArray(field, numericColumns) > -1) {
                    sortResult = compareSimple(value1, value2) * sign;
                } else {
                    sortResult = compareAlphaNumeric(value1, value2) * sign;
                }
            }
        }
        return sortResult;
    });

    grid.invalidate();
    grid.render();
}
