Asp.net 2.0 Treeview Control-How to use expand collapse without images

I have a treeview control with one root, 2 parents and several nodes. The expand collapse is working fine for the menu structure but can I use the control without the +- image or use an empty image?? The html code is below. Any help would be appreciated, thank-you very much.

<asp:TreeView ID="TreeView2" runat="server" DataSourceID="XmlDataSource3" style="font-size: 10pt; font-family: Arial; position: absolute; left: 455px; top: 118px; width: 280px" NodeIndent="0" Height="81px" Width="197px" EnableViewState="False" MaxDataBindDepth="2" ExpandDepth="2" >
            <DataBindings>
                <asp:TreeNodeBinding DataMember="UWDocs" TextField="text" SelectAction="None"/>
                <asp:TreeNodeBinding DataMember="CertificateOfFacReHeading" TextField="text" ValueField="text" selectAction="Expand"/>
                <asp:TreeNodeBinding DataMember="CertificateofFacReDocList" NavigateUrlField="url"
                    TextField="text" ValueField="text" ImageUrlField="#Value" />
                <asp:TreeNodeBinding DataMember="LapsedCancelledBusMemoHeading" TextField="text"
                    ValueField="text"  SelectAction="Expand"/>
                <asp:TreeNodeBinding DataMember="LapsedCancelledBusinessMemoDocList" NavigateUrlField="url"
                    TextField="text" ValueField="text" />
 </DataBindings>
            <ParentNodeStyle Font-Names="Arial" Font-Size="10pt" Width="280px" />
            <SelectedNodeStyle Font-Names="Arial" Font-Size="10pt" />
            <RootNodeStyle Font-Names="Arial" Font-Size="10pt" ForeColor="Black" cssClass="GeneralRoot"  BackColor="Transparent" Width="300px"/>
            <NodeStyle Font-Names="Arial" Font-Size="10pt"  VerticalPadding="2px" Width="280px" HorizontalPadding="1px" ForeColor="SlateBlue" CssClass="mynode"/>
            <LeafNodeStyle Font-Names="Arial" Font-Size="10pt" /> 
            <HoverNodeStyle BackColor="#EAEAF5"  />
        </asp:TreeView>
        <asp:XmlDataSource ID="XmlDataSource3" runat="server" DataFile="~/Canadian/CanadianXMLTesting/CanadianHomePageUWDocumentsMLFile.xml">
        </asp:XmlDataSource>

Does you solution apply to windows.forms or web forms? For webforms, I think only way to do this is to either find another image or script the functionality of the treeview. I will keep looking for an resolution and thank you very much for your help with this.

good question -- I think that applies to the web forms more than the windows forms, want me to check further?

No, but thank you. I think I will try to find another image. The xml and treeview navigation works so well without a single line of coding, I want to use it and workaround the image problem.
