Answer 1

You need to set a NagivateUrl equal to a Javascript function in the TreeView node to hide the button.

<asp:TreeView ID="TreeView1" runat="server" >
        <Nodes>
            <asp:TreeNode Text="" Value="" NavigateUrl="javascript:HideButton();"></asp:TreeNode>
        </Nodes>
    </asp:TreeView>

 <script type="text/javascript" language="javascript">
    function HideButton() {
        document.getElementById('<%=Button1.ClientID %>').style.visibility = "hidden";
    }
</script>
