It would be nice to have sorting indicators/arrows in a header on multiple columns. This would show users that these columns are sortable. To my understanding, it is NOT possible to enable that functionality with standard function setSortImgState(x,y,z) as it sets up image and sorting state for one column only.
My plan is to set up custom onHeaderClick or onBeforeSorting event handler and use complex header:
mygrid.setHeader(“Header0,Header1,
In the body of my event handler I can find “hdr2img” object and replace image src with “images/arrow_down.gif”. Is this the best solution to this problem ? Could you recommend anything else or do you plan to include such functionality in a future release of dhtmlx grid ?
