any event/call back for grid column selection ?

is there any event/call back for dhtmlXGridObject column selection ?

You can use “onRowSelect” event:
mygrid.attachEvent(“onRowSelect”,function(rowId,cellIndex){});
You can find list of all available event here dhtmlx.com/docs/products/dhtmlxG … rid_api_ev

my question was different. I was asking for event on column selection. do we have something for it. ?

There is no possibility to select whole column in grid.
