title: How to select certain child node in TreeView, C#
body: <p>I am having a problem with selecting a certain child node.</p>
  
  <p>What I want to achieve: I you have this treeview for example (one parent with two child nodes): <br> Parent <br> -Child with a value 5 <br> -Child with a value 2.</p>
  
  <p>I want to add these two values and assign them to Parent node: <br><br> Parent result 7<br> -Child 5 <br> -Child 2.</p>
  
  <p>Of course, a bigger treeview would have several parents and lots of children and they will all add up to one root node.</p>
  
  <p>How can I do this?? pls help.</p>
  
  <p>thx,<br> Caslav</p>
