I have a .NET 2.0 web form that has a Treeview control bound to an
XmlDataSource control bound to the following XML document (only the relevant
part of the document is shown here):

 <TC1710 A="1" GQ="0" GQ1="0" GQ2="0" PS="0" GC="0" LC="0" OL="">
  <TC5485 A="0" GQ="0" GQ1="0" GQ2="0" PS="0" GC="0" LC="0" OL="" />
  <TC0191 A="0" GQ="0" GQ1="0" GQ2="0" PS="0" GC="0" LC="0" OL="">
   <TC8133 A="0" GQ="0" GQ1="0" GQ2="0" PS="0" GC="0" LC="0" OL="">
    <TC8151 A="1" GQ="0" GQ1="0" GQ2="0" PS="0" GC="0" LC="0" OL="" />
    <TC1773 A="1" GQ="0" GQ1="0" GQ2="0" PS="0" GC="0" LC="0" OL="">
     <TC1779 A="1" GQ="0" GQ1="0" GQ2="0" PS="0" GC="0" LC="0" OL="" />
    </TC1773> />
   </TC8133> />
  </TC0191>
 </TC1710>

I set the XPATH of the XmlDataSource to "//TC1710/descendant::*" with the
intention of selecting the descendant nodes of the TC1710 node expecting:
TC5485
 -TC0191
  --TC8133
  ---TC8151
  ---TC1773
  ----TC1779

But instead, each node that is within each descendant is displayed again as
separate branches:
TC5485
 TC0191
  -TC8133
   --TC8151
   --TC1773
    ---TC1779
 TC8133
 - TC8151
 - TC1773
  -- TC1779
 TC8151
 TC1773
 - TC1779
 TC1779

Shouldn't each node be displayed only once?

There are no duplicates in the XML document. I have not been able to
determine if this is an issue with my XPATH syntax, the XmlDataSource, or
the Treeview control.

I really need to be able to display the nodes as organized in the XML
document. This is my first XPATH project so any help will be greatly
appreciated.
