I am using visual basic for coding. I drag & dropped a tree view control and edited its nodes. Now when I run my page I get this error->
Control 'TreeView1' of type 'TreeView' must be placed inside a form tag with runat=server.
In the source I have the following entry
asp:TreeView ID="TreeView1" runat="server" Height="155px" Style="z-index: 100; left: 41px; position: absolute; top: 108px" Width="1px" ImageSet="Contacts" NodeIndent="10"
