Load .aspx page on another frame from TreeView Event

Hi All,

See my Default Page HTML code:

<frameset cols="25%,*">
<frame name="TreeView" src="TreeView.aspx" />
<frame name="DataDisplay" src="DataDisplay.aspx" />
</frameset>

I have a treeview (treeview nodes are created dynamically from a database) in TreeView.aspx. When the user clicks on the TreeNode, it should open some another aspx page in the right side frame called "DataDisplay".

I am using SelectedNodeChanged event in TreeView.aspx. Is this the right event to use? How to initiate aspx page in the second frame?

SelectedNodeChanged Event code:
protected void TreeView1_SelectedNodeChanged(object sender, EventArgs e)
{
string strSelected = ((TreeView)sender).SelectedNode.Value.ToString();

switch (strSelected)
{
case "Node1":
// Response.Write(strSelected);
// What code should I put here...
break;
}
}

Can anyone help me?
