Question

I saved my column permutation info into a table. This information can be reloaded in beforeRequest event:

mynewperm = {....};

myGrid.jqGrid("remapColumns", mynewperm, true);

The columns are reordered correctly. However I lost the header icon. Now if I click any column header, I can not see
the sort icon anymore, then can not sort any column. How can I get it back?

Thank you,

yh

Indeed if you look at the jquery.jqGrid.src.js source, the line is:

var previousSelectedTh = ts.grid.headers[ts.p.lastsort].el, newSelectedTh = ts.grid.headers[idxcol].el;

Line #1982 in my version. I fixed it by modifying the file and added this just before that line:

        if (ts.p.lastsort < 0)  // johnl.
            ts.p.lastsort = 0;

The problem was that ts.p.lastsort was -1.
