Display all child nodes of selected node of treeview in textbox in vb.net -


not sure on how around this.

i able display current selected node in textbox (or richtextbox) doing following:

private sub treeview1_afterselect(sender object, e treevieweventargs) handles treeview1.afterselect      richtextbox1.text = e.node.text  end sub

however, can't figure out way of displaying all child nodes of selected parent.

would able point me in right direction?

you need called recursive subroutine drill down child nodes of each node iterate through them:

private sub treeview1_afterselect(sender object, e treevieweventargs) handles treeview1.afterselect      dim mynode treenode = e.node      textbox1.text = mynode.text      getchildnodes(mynode)  end sub  sub getchildnodes(tnode treenode)      'iterate through child nodes of node passed subroutine     each node treenode in tnode.nodes          textbox1.text += node.text          'if node passed subroutine contains child nodes,         'call subroutine each 1 of them         'if want display 1 level deep, comment out         'if statement.         if tnode.nodes.count > 0 getchildnodes(node)      next  end sub
