I'm using VB to generate a tree menu from an xml file. The problem is that if the xml file is not found then the page blows up. I don't want this to happen. We are using contribute, so if a person generates a draft, which is moved to a draft folder, the xml file is not there. I need a way for a default message to display when the xml file is not found instead of the page blowing up. Thanks a bunch. I'm really new to .Net, so sorry if this is a noob question

PHP Code:
<form runat="server">

            <
asp:XmlDataSource ID="MySource" DataFile="xml/links.xml" XPath="MSCHome/links[@name='menu']/*" runat="server"/>
        
            <
asp:TreeView 
                Id
="MyTree"
                
DataSourceId="MySource" 
                
SkinId="MSDN" 
                
OnSelectedNodeChanged="MyTree_Select" 
                  
NodeStyle-ForeColor="Black"
                    
NodeStyle-Font-Names="Verdana"
                    
NodeStyle-Font-Size="8pt"
                    
NodeStyle-HorizontalPadding="5"
                    
NodeIndent="10"
                  
ExpandDepth="0"
                
runat="server">
            
                <
Databindings>
            
                    <
asp:TreeNodeBinding DataMember="links" TextField="name" />
                    <
asp:TreeNodeBinding DataMember="mainlink" TextField="name" NavigateUrlField="url"/>
                       <

                    <
