How to pass column index or column id to data processor

In below coding, I’m able to pass the row id to data processor and retrieve the row id with classic ASP coding as per below. My question is, how do I pass the column index/column id to data processor.

	strIds = Request.Form("ids")
myDataProcessor = new dataProcessor("dp1.asp");
myDataProcessor.setTransactionMode("POST", true);

mygrid.attachEvent("onFilterStart", function(column_indexes,column_values){

myDataProcessor.attachEvent("onAfterUpdate",function(sid, action, tid, tag){
    var url = tag.getAttribute("url");
     if(url) document.location.href = url;

mygrid.attachEvent("onCheck",function(rowId, cellInd, state){
	if (state){
		myDataProcessor.setUpdated(rowId, true);
	else {
		myDataProcessor.setUpdated(rowId, false);

You are using “send-all-changed-data-at-once” mode, in which all data is encoded in POST request by next scheme … ding_modes

Basically if row id is “123”

you have POST params as
123_c0 - data from first column

123_cN - data for last column
