Here's the code I'm using to load up the grid, which works just fine:

    
            function gridCreated(sender, eventArgs) { 
        
                loadData(sender); 
        
            } 
        
            function loadDataCallback(result, userContext) { 
        
                var tableView = userContext.get_masterTableView(); 
        
                tableView.set_dataSource(result.firstChild.children); 
        
                tableView.dataBind(); 
        
            } 
        
            function loadDataFailedCallback(error){ 
        
                alert(String.Format("Load data for {0} failed.", error.get_message())); 
        
            } 
        
            function loadData(grid) { 
        
                //set up the default callbacks and context for our service before calling it 
        
                var serviceProxy = new Cadie.Bridgeworks.Services.AARMS(); 
        
                serviceProxy.set_defaultSucceededCallback(loadDataCallback); 
        
                serviceProxy.set_defaultFailedCallback(loadDataFailedCallback); 
        
                serviceProxy.set_defaultUserContext(grid); 
        
                serviceProxy.GetArchList(0, ""); 
        
            }

This loads the data from the web service correctly. The problem is, I get a grid full of empty rows. Here is the code I've used to create the grid:

    
            <telerik:RadGrid ID="clientGrid" runat="server" AutoGenerateColumns="false" 
        
                AllowPaging="true" AllowSorting="true"> 
        
                <ClientSettings> 
        
                    <ClientEvents OnCommand="function(){}" OnGridCreated="gridCreated"/> 
        
                </ClientSettings> 
        
                <PagerStyle Mode="NumericPages" Position="TopAndBottom" /> 
        
                <MasterTableView> 
        
                     <Columns> 

                         <telerik:GridBoundColumn HeaderText="Name" DataField="arch_name" />

                     </Columns> 
        
                </MasterTableView> 
        
            </telerik:RadGrid>

The end result of this is a grid with the correct number of rows, but none of the rows actually display anything. there is a node in the XmlNode returned by the web service called arch_name.

Should I not be using web services that return XmlNodes? Would it be better to have the webservice return a List<T> that has the properties I want to display serialized to json, rather than the XmlNode with the ResponseType set to Xml?

I've been using the example you mentioned, and that's how I've gotten the loading and everything to work, but the problem comes when trying to get the actual data to display
