xml.tag!(“rows”) do
@empdata.each do |empdet|

xml.tag!(“cell”, empdet.empaddr)
end
end
end
And my emplists.rxml file is as below
xml.instruct! ml, :version=>“1.0”
xml.tag!(“rows”) do
@empprojectlist.each do |empproj|
xml.tag!(“row”,{ “id” => empproj.id }) do
xml.tag!(“cell”, empproj.empprojlist)
end
end
end
As per the above code i am getting my grid and the data1.rxml value loaded in it.
and in that javascript file i created the combo object.and i am trying to load the emplists.rxml data into the combo of the grid in the column “1”.you can see that in the above JavaScript code. But the value is not loaded into the combo.And the javascript file i have included is dhtmlx.js and dhtmlx.css its taken from the dhtmlx_pro_full file Please help me out of this. Its very urgent .Any suggestions are welcome.
Thanks 
Please try to following order of commands:
grid.loadXML("/admin/data1",function(){
co = grid.getColumnCombo(1);
co.loadXML("/admin/emplists");
});
I tried what you told
data1.rxml is getting loaded into the grid but not the emplists.rxml into the combo.Is that emplists.rxml file defined is correct.
And is there any javascript file dependency is there Because the instance for “co” the combo object is not getting created.And i am using dhtmlx.js and dhtmlx.css from dhtmlx_pro_full file.Please help me out.
