I would use the generic

var column1 = table.rows[rowIndex].cells[0].childNodes[0].nodeValue;

with the more reliable

var column1 = [];

for (var c = table.rows[rowIndex].cells[0].childNodes, i = 0;
i < c.length; i++)
{
column1.push(c[0].nodeValue);
}

column1 = column1.join("");

or (from DOM Level 3 Core)

var column1 = table.rows[rowIndex].cells[0].textContent;

Column 2 does not contain non-whitespace text nodes, therefore .textContent
will not yield anything but whitespace.

Suppose you wish to retrieve the value of the `input' element, you would
retrieve the object reference with

var o = document.forms[...].elements["DataGrid1__ctl2_textBox"];

(preferable) or

var o = document.getElementById("DataGrid1__ctl2_textBox");

and then (after a runtime feature test) access

o.value


BTW, the first `td' element should probably be a `th' element.

Should read

column1.push(c[i].nodeValue);

of course.

Thanks a lot.
