Is it possible to change width of a column in slickgrid programatically?

Question

I tried grid.getColumns[index].width = <>. But, that doesn't resize the column.

Answer 1

You need to re-apply the column settings to the grid after you have modified the column width.

$("#resize").click(function () {
    var cols = grid.getColumns();
    cols[0].width = 120;
    grid.setColumns(cols);
});
