vb.net - Find all checked nodes of parent node in treeview -

i have been trying search web information regarding child nodes, seem find i'm looking for.

basically, problem this: have determined if parent node checked in treeview control. need loop through child nodes of parent determine children checked , load these array.

as know parent node, hoping don't have loop through nodes again. want loop through child nodes of specified parent.

hope makes sense.

my treeview looks similar this:

name   -->name 1   -->name 2   -->name 3   -->etc code   -->code 1   -->code 2   -->code 3   -->etc 

so example this:

 if trvfilter.nodes.item(trvfilter.nodes.indexofkey("name")).checked = true              'loop through child nodes of parent node (name)              'if child node checked, add name of child node array          end if 

sorry if seems simple, i'm new vb.net , can't work out how loop through child nodes of selected parent.

thanks in advance

trvfilter.nodes collection of treenode, can loop through them for-each

for each tvn treenode in trvfilter.nodes   ' stuff tvn  next
