Here I want to trace all the TreeNodes  of a Treeview Control. Please help me out. I've a req like i need to make Visible false for some sub nodes of the Treeview as per user Rights.

Calling A function from Page_Load()
ListNodes(Misc_Treeview);


<pre lang="cs">

{
  foreach (TreeNode nodes in TreeView1.Nodes)
  {
     //int count = 0;
     var V = nodes.ChildNodes;

     foreach (var item in V)
     {

      //count++;
     }


   }
}
</pre>

先谢谢。

Thanks in advance.

推荐答案

private void PrintRecursive(TreeNode treeNode)
{
   //do something with each node
   //System.Diagnostics.Debug.WriteLine(treeNode.Text);
   foreach (TreeNode tn in treeNode.Nodes)
   {
      PrintRecursive(tn);
   }
}

// Call the procedure using the TreeView.
private void CallRecursive(TreeView treeView)
{
   // Print each node recursively.
   TreeNodeCollection nodes = treeView.Nodes;
   foreach (TreeNode n in nodes)
   {
      PrintRecursive(n);
   }
}

调用下面的递归方法

call the recursive method as below

CallRecursive(Misc_Treeview);
