I have a tree view structured like this

 Node0
   -Node1
      -Node11
      -Node12
   -Node2

And i have two panels: panel11 & panel12. I want to show panel11 if Node11 is selected & if Node12 is selected i want to show panel12. How can i do that in my WF in C#?

Write a handler for the AfterSelect event on the treeview, where you can do whatever you have to do to handle the node that the user selected.

 private void TreeView1_AfterSelect(object sender, TreeViewEventArgs e)
 {
    if (e.node == nodePanel11)
    {
       Panel11.Visible = true;   // This presumes that the panel already exists 
                                 // and is invisible
       Panel12.Visible = false;
    }
    else if (e.node == nodePanel12)
    {
        Panel12.Visible = true;
        Panel11.Visible = false;
    }
 }
