title: attach a panel to TreeView control
body: <p>I am beginner in c#. In my project, I populated a xml file inside a TreeView control. If the xml file is large, the <code>TreeView</code> control is showing the data with scroll bars. Beside this, whenever the user double clicks a node I am showing a panel beside the selected node something like this..</p>

  <p>My question is how to make the <code>panel</code> attached to <code>treeView</code> control so that eventhough the user scrolls the <code>TreeView</code> control the panel should also move along with the selected node.</p>
