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 was inspired by Mr.Hunts answer but I took a slightly different approach to extend the current grid.setSortColumn(columnId, isAsc) to grid.setInitialSortColumn(columnId, isAsc). This will apply the sort and do everything grid.setSortColumn does.

    var thisGrid = { //Your grid obj
        columns: , // Your columns object
        grid: , // new Slick.Grid....
    }



    thisGrid.grid.onSort.subscribe(function (e, args) { // ar  var cols = args.sortCols;]
            thisGrid.grid.customSort(args);
        });

    thisGrid.grid.customSort = function (args) {
        var cols = args.sortCols;
        thisGrid.dataView.sort(function (dataRow1, dataRow2) {
                if (cols) {
                    for (var i = 0, l = cols.length; i < l; i++) {
                        var field = cols[i].sortCol.field;
                        var sign = cols[i].sortAsc ? 1 : -1;
                        var value1 = dataRow1[field],
                            value2 = dataRow2[field];
                        var result = (value1 == value2 ? 0 : (value1 > value2 ? 1 : -1)) * sign;
                        if (result != 0) {
                            return result;
                        }
                    }
                }
                return 0;
            });
    }
    thisGrid.grid.setInitialSortColumn = function (columnId, ascending) {
        thisGrid.grid.setInitialSortColumns([{
                    columnId: columnId,
                    sortAsc: ascending
                }
            ]);
    };
    thisGrid.grid.setInitialSortColumns = function (cols) {
        sortColumns = cols;
        $.each(sortColumns, function (i, col) {
                var columnIndex = thisGrid.grid.getColumnIndex(col.columnId);
                var column = thisGrid.columns[columnIndex];
                if (col.sortAsc == null) {
                    col.sortAsc = true;
                }
                var args = {
                    grid: thisGrid.grid,
                    multiColumnSort: true,
                    sortCols: [{
                            sortCol: column,
                            sortAsc: col.sortAsc
                        }
                    ]
                }
                thisGrid.grid.setSortColumn(col.columnId, col.sortAsc);
                thisGrid.grid.customSort(args);

            });
    };

    // Trigger 
    thisGrid.grid.setInitialSortColumn("dateDue", true);
