How can I disabled col sorting on the second row of a multi row header (and keep enabled the col sorting on the first row) ?
thanks
Actually you can’t disable sorting behavior for some header row in grid, it will work for all rows or will not work at all.
You can try to modify
dhtlmxgrid.js , line 2539
this.sortField = function(ind,repeatFl,r_el){
if (this.hdr.rows[1] != r_el.parentNode) return; // block any row except first
