Answer 1

I coded the following to give you direction:
1. In the "Element Attributes" section of the DEPTNO column, I call a javascript function as:
onchange = "javascript:updateTable(this);"2. I wrote a simple javascript function that shows an alert when the user changes the select list as:
<script language="JavaScript" type="text/javascript">
function updateTable(pThis)
    var vRow = pThis.id.substr(pThis.id.indexOf('_')+1);
    alert('Row# - '+ vRow + ' has the value - ' + pThis.value);
</script>Now, you can call a AJAX on-demand process inside the javascript function to update the database value.
