Thanks a lot. It works in the first row of header great. I have just a problem with the second row of header. Contextmenu is horizontal offseted and by higher cellIndex is not visible.
I use following codes:

menu = new dhtmlXMenuObject(null,"dhx_blue");
menu.setImagePath("/images/");
menu.setIconsPath("/images/");
menu.attachEvent("onBeforeContextMenu",header_pre_function);
menu.loadXML("...");
menu.renderAsContextMenu();
menu.attachEvent("onClick",onButtonClick);
               
mygrid = new dhtmlXGridObject('grid_div');
mygrid.enableContextMenu(menu);
mygrid.setImagePath("/imgs/");
mygrid.loadXML('myXML');
mygrid.attachEvent("onBeforeContextMenu",pre_function);
           
for(var i = 0; i < mygrid.hdr.rows[1].cells.length;i++){
   var index = 100+i;
   mygrid.hdr.rows[1].cells[i].id = "zone_"+index;
   menu.addContextZone("zone_"+index);
}
if(mygrid.hdr.rows.length = = 3){
   for(var i = 0; i < mygrid.hdr.rows[2].cells.length;i++){
      var index = 200+i;
      mygrid.hdr.rows[2].cells[i].id = "zone_"+index;
      menu.addContextZone("zone_"+index);
   }
 }
..

function header_pre_function(zone_id){
   var index = zone_id.split("_")[1];
   var cellInd = index%100;
   var rowInd = parseInt((index/100))-1;
   if(cellInd != 0){
      var cellVal = mygrid.getColumnLabel(cellInd,rowInd);
      ctmn_pre(cellVal); // another function
      return true;
    }
    else
      return false;
  }

and my xml file:
           <head>
          <column ... >A</column>
          <column ... >#cspan</column>
          <column ... >B</column>
          <column ... >#cspan</column>
          <column ... >C</column>
          <column ... >#cspan</column>
          ...

       <afterInit>
          <call command="attachHeader"><param>a1,a2,b1,b2,c1,c2,...</param></call>
          ...
       </afterInit>
      </head>

Thanks in advance!
