Insert/delete/edit rows in a GridView when datasource is set to an xml content

[Andy B]

I have a GridView in asp.net. I want to set its datasource to some xml
content. At the same time, I need to know how to insert/delete/edit content
in the GridView rows and then repopulate the xml source to reflect the
changes made in the gridView. Is there any simple examples of doing
something like this or can somebody create one for me?

Thanks for the help...
