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
grid.SetSortColumn(colName,true/false)
You can trigger click event on the column header...which does sorting
I fixed the issue like this...
$('.slick-header-columns').children().eq(0).trigger('click'); // for first column
