The reason you get the error that "FpSpread1 is undefined" is that when
ASP.NET renders server controls it adds the namingcontainer id as a prefix to
the control id.
Instead of using the document.getElementById, try something like this:
var table = findControl("FpSpread1");
if (table !=null) //do all of the processing that you want
and write a function as this:
<script language="javascript">
function findControl(ControlName)
{
var aTables = document.getElementsByTagName("table");
if (aTables)
{ for (var i=0; i < aTables.length ; i++)
{
if (aTables[i].id.lastIndexOf(ControlName) == aTables[i].id.length -
ControlName.length)
{
ret =aTables[i];
}
}
}
return ret;
}
</script>
