Exporting Treeview data to excel sheet using C#

Hi,

I am using Visual Studio 2010. I have a form which has a treeview control which generate values from an xml file. When I select a particular treeview node, I need to export the selected node data and its child nodes to an excel sheet as rows and columns.

Could any one guide me how can I proceed with this?

Appreciate your immediate response.

Thanks
Asha
