Hi
I have a crucial problem deciding the concept.

Requirement :

I have the following requirements.
I have xpathdocument want to display in table format
sorting columns
paging
any column may have link(Anchor).

performence is the main issue.

i could not decide using datagrid,datalist or datarepeater with custom sorting and paging or xml/xsl.
when we compare server control and xml/xsl which is efficient.

i want to display the data in table format with all boue funtionality and performence is main criteria.

Please help me which is efficient performence technique.Any option is open only thing is data is in xml format.
this site may have more than millon hits.

Thanks
Ravi

If you easily want to enable paging and sorting, then you have to use the DataGrid.  The other two data controls don't support this. This doesn't mean you can't do it though!, you just have to create your own interface that handles this, the PagedDataSource class helps with the paging part too.

Honestly though, if you want the absolute best performance, then I wouldn't use any of them.  I read an article once that showed how much slower these controls are when you compare it to just doing it yourself.  They save you a ton of time programming, but they do have overhead for all the features you don't use in them.

Agreed, the datagrid is the most efficient to code, the others offer more control, but require more overhead.

Hi Raterus

I agree what you daid.But All options are open ,So please suggest me the best technique to implement  with my requirements.

I have simple class will do the sorting here is the code:
Even i am not sure  wheather it is efficient way of sorting or not.

XPathDocument xpathDoc = new XPathDocument(Server.MapPath("XMLFile3.xml"));
                  XPathNavigator nav = xpathDoc.CreateNavigator();

                  XPathExpression expr;
                  //expr = nav.Compile("UPS/Summary/SummaryInformation[@PickUpRecord=6481802191]/Details/DetailInformation");
                  expr = nav.Compile("Persons/person");
                  string nameee="FirstName";
                  expr.AddSort(nameee, XmlSortOrder.Ascending, XmlCaseOrder.None, "", XmlDataType.Text);
                  XPathNodeIterator iterator = nav.Select(expr);
                  int i=0;
                  while(iterator.MoveNext())
                  {
                  
                        Response.Write(iterator.Current.Value+"<Br>");
                  }

Thanks

Could you possibly load this xml file into a Dataset, using the DataSet's "ReadXML" method?
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfSystemDataDataSetClassReadXmlTopic.asp

If you can get it into a DataSet, you have much more control over the final appearance.  I would concentrate on using the Datagrid too.  You probably can also bind to the xml iterator you have shown in your example, I've never done this, so I couldn't even tell you how to start, but it probably implements ienumerable, which means you can bind that directly to the datagrid as well.
