//var Dcode = document.FrmDCode.btnSave.value ;
var Dcode = document.all.table1.innerHTML;
//var Dcode = eval(document.all.table1.txtDcode.value);
//var Dcode = document.all.table1.txtDcode1.Value;
alert(Dcode);
var Dcount = document.getElementById("htncount").value;
alert(Dcount);
for(var cnt= 1 ;cnt<=Dcount;cnt++)
{
var Dcodeold = document.getElementById("htnDcode").value;
var DcodeNew = eval("document.getElementById('txtDcode"+cnt+"').value");
document.getElementById("htnDcode").value = Dcodeold + "|" +DcodeNew ;
//var Dcount = document.getElementById("txtDcode"+cnt).value;
//alert("document.getElementById(\""txtDcode"+cnt+"\"").value");
}
alert(document.getElementById("htnDcode").value);
}

function delRow(TDid,TRid,RowId)
//function delRow(TDid,TRid)
{
selTD = document.getElementById(TDid);
selTR = document.getElementById(TRid);
intRowSpan = selTD.getAttribute("rowSpan");
intRowIndex = selTR.getAttribute("rowIndex");

intInsPos = intRowSpan + intRowIndex ;
//alert(RowId);
//alert("intRowSpan:" + intRowSpan);
//alert("intRowIndex:"+ intRowIndex);

document.all.table1.deleteRow(RowId);
//document.all.table1.deleteRow(this.intRowIndex);
//document.all.table1.deleteRow(this.intRowSpan);
//document.all.table1.deleteRow(intInsPos-1);
//selTD.setAttribute("rowSpan",selTD.getAttribute("rowSpan")-1);
}

function insRow(TDid,TRid)
{

selTD = document.getElementById(TDid);
selTR = document.getElementById(TRid);
intRowSpan = selTD.getAttribute("rowSpan");
intRowIndex = selTR.getAttribute("rowIndex");

intInsPos = intRowSpan + intRowIndex ;

var oTR = document.all.table1.insertRow(intInsPos);
//var RowId = intInsPos - 2 ;
var RowId =intInsPos;

var oC1TD = oTR.insertCell(0);
