Hi to all!!!!

I have a problem with performance of a template working in browser mode.  It
seems that filling a repeating table using a XmlWriter is the case.

First I tried to fill like this:

foreach (DataRow row in dataTable.Rows)
{
               string myNamespace = NamespaceManager.LookupNamespace("my");
               using (XmlWriter writer =
MainDataSource.CreateNavigator().SelectSingleNode("/my:myFields/my:group1",
NamespaceManager).AppendChild())
               {
                              writer.WriteStartElement("Values",
myNamespace);

                              writer.WriteElementString("Value1",
myNamespace, row["Value1"].ToString());
                              writer.WriteElementString("Value2",
myNamespace, row["Value2"].ToString());
                               writer.WriteElementString("Value3",
myNamespace, row["Value3"].ToString());
                              writer.WriteElementString("Value4",
myNamespace, row["Value4"].ToString());
                              writer.WriteElementString("Value5",
myNamespace, row["Value5"].ToString());

                              writer.WriteEndElement();        
                              writer.Close();
               }
}

While opening in browser after about half a minute a dialog box apper saying
that "A Scripts on this page is causing Internet Explorer to run slowly. If
it

continues to run, your computer may become unresponsive".

The InternetExplorer 7 has at this time OVER 0,5 gigs in the task
manager!!!!!!!! (The server an the client is up-to-date with all services
packs)

It seemed to me that AppendChild() method is the problem so I tried first to
generate the xml with the data to MemoryStream:

MemoryStream memoryStream = new MemoryStream();
XmlWriter memoryXmlWriter = XmlWriter.Create(memoryStream);

string myNamespace = NamespaceManager.LookupNamespace("my");

foreach (DataRow row in dtTasks.Rows)
{
               memoryXmlWriter.WriteStartElement("Values", myNamespace);

                memoryXmlWriter.WriteElementString("Value1", myNamespace,
row["Value1"].ToString());
               memoryXmlWriter.WriteElementString("Value2", myNamespace,
row["Value2"].ToString());
               memoryXmlWriter.WriteElementString("Value3", myNamespace,
row["Value3"].ToString());
               memoryXmlWriter.WriteElementString("Value4", myNamespace,
row["Value4"].ToString());
               memoryXmlWriter.WriteElementString("Value5", myNamespace,
row["Value5"].ToString());
             
               memoryXmlWriter.WriteEndElement();
}

memoryXmlWriter.Flush();
memoryXmlWriter.Close();

string outStr = Encoding.UTF8.GetString(memoryStream.ToArray());

//Add "my:" and "/my:" prefix
string rtXml = AddPrefixMy(outStr);

And then replace directly repeating table InnerXml:

MainDataSource.CreateNavigator().SelectSingleNode("/my:myFields/my:group1",
NamespaceManager).InnerXml = rtXml;

While opening in browser nothing changes and the same dialog box appers.

Do you have any ideas how to optimize this code.

Thanks for ANY reply !!!!!!!!!!!!!!!
