Hi Peter, Travis and everyone--
Peter, you're right. We are using an AJAX approach.
I tried using different Table properties (insertRow, appendChild),
etc. I couldn't get any of them to work. I changed
my "insertAdjacentHTML" to innerHTML, but that didn't help.
I am very, very new to all of this and have been trying to solve this
issue for several days (tearing code apart over and over and trying
new ways) -- which has produced no results other than my frustration
and desperation.
Maybe I'm going down the completely wrong path here. Essentially,
here is an explanation of my ASP.NET webform application and what I
want it to do:
Employees add how much time they spend on a job, and then that
information is added to a SQL database and displayed in a datagrid.
I've got everything working on the client side, except the refreshing
of the datagrid.
When the page loads and/or when a new record is added, I want the
datagrid to update (without the page refreshing). The information
that is returned is in XML format, and I somehow have to get it into
the datagrid.
Here's one record of the XML that is returned into variable
oResult.value:
"<ROOT><NewDataSet>
<ActivityHistory>
<ActivityID>312</ActivityID>
<CustomerName>Test</CustomerName>
<Description>312-Development</Description>
<ActivityDate>2005-08-10T00:00:00.0000000-05:00</ActivityDate>
<ReferenceCode>J-1007</ReferenceCode>
<Minutes>15.00</Minutes>
</ActivityHistory>
</NewDataSet></ROOT>"
But for a given period of time, there will be several of these
ActivityHistory records.
Below is the function I have so far, but as I said, I could be going
down a completely wrong path. I would greatly appreciate if any of
you have corrections for my code or if you have ideas/suggestions for
a different/better way to do this (since my way doesn't work,
anything would be better). Yes, I'm a newbie, and I'm just
not "getting" this at all. I have no idea what to do now that
nothing has worked thus far.
function LoadTable()
{
var Employee = document.getElementById
("_ctl1__ctl0_ddlEmployee").value;
var StartDate = document.getElementById
("_ctl1__ctl0_TextStartDate").value;
var EndDate = document.getElementById
("_ctl1__ctl0_TextEndDate").value;
// Update the xml island with the employee history
information
var oResult = Methods.EmployeeActivity(Employee,
StartDate, EndDate);
var xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async=false;
xmlDoc.load("activityhistory.xml");
var loaded = xmlDoc.loadXML(oResult.value);
if (loaded) {
var xslDoc=new ActiveXObject
("Microsoft.XMLDOM");
xslDoc.async=false;
xslDoc.load("ActivityHistoryStyle.xsl");
document.getElementById
("Table1Inner").innerHTML = xmlDoc.transformNode(xslDoc);
}
}
Thanks!
