Adding childs to a treenode dynamically in c#

Question

I want to dynamically add some child nodes to a root node in my TreeView. I have a string Array of some names like {\"john\", \"sean\", \"edw

Answer 1

I think the problem is that you do not inform the mainNode that child is its children, something like: mainNode.Children.Add(child) (in the for block). You just create the child node, but you don't do anything with it for it to have any relation with the TreeView or with the mainNode.

Answer 2

You need to append the child node to the parent, here's an example:

TreeView myTreeView = new TreeView();
myTreeView.Nodes.Clear();
foreach (string parentText in xml.parent)
{
   TreeNode parent = new TreeNode();
   parent.Text = parentText;
   myTreeView.Nodes.Add(treeNodeDivisions);

   foreach (string childText in xml.child)
   {
      TreeNode child = new TreeNode();
      child.Text = childText;
      parent.Nodes.Add(child);
   }
}
