    There’s some information here about enabling the expand/collapse on the client. See the Enabling Client Script section.

    Basically you need to set EnableClientScript to true for the control.

    TreeView1.EnableClientScript = true;

    Or

    <asp:treeview id="..." runat="server" EnableClientScript="true" ... />
