HELP: ASP.NET & XML DataGrid.... woes :S

[dhruba.bandopadhyay]

I need advise on ASP.NET & XML.

I got a Web Service that I call in real-time to generate a XML document
(in
main memory, not file). I could use the .NET built-in XML document
generation classes, but Web Service does the same I guess.

1. Is it possible to feed this XML document object into a
DataGrid/View/List
without saving the XML object to file? I seen examples where they load
the
XML document from file. I don't want to do this as I generate a XML
document
by hand calling the Web Service.

2. Is it possible to handle specific events in the DataGrid/View/List -
such
as Cell_OnClick, Cell_OnDrag? I want to click on a cell and then a text
box
appears in that cell so I can change the value. Or I want to drag a row
and
move it up/down. Then I will handle the event and update the Web
Service
with new data.

3. What DataGrid-like controls are there and their
differences/advantages/strong-points? DataView? DataList?
