Hi Gurus,

I'm using a RadTreeView to pick an item from a list of hierarchical data and I want to display details for that item in a DetailsView control.

I have it woking, but it is VERY slow. After the user clicks on an item it takes quite a long time (relatively) to populate the DetailsView via AJAX.

I tested with a DropDownList control and it is very quick. The DetailsView loads really fast.

I'm thinking maybe I'm doing something wrong with your RadTreeView so maybe you can help me out?

Here are the details...

I set up the RadTreeView with an OnNodeClick event like so...

    
                <telerik:RadTreeView ID="RadTreeView1" Runat="server"   
        
                    DataSourceID="SqlDataSource1" 
        
                    DataFieldID="ServiceLineID" 
        
                    DataFieldParentID="ParentID" 
        
                    DataTextField="ServiceLineName" 
        
                    DataValueField="ServiceLineID" 
        
                    OnNodeClick"RadTreeView1_NodeClick"> 
        
                </telerik:RadTreeView>

I have a Master Page so I'm using a RadAjaxManagerProxy like so...

    
                <telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">  
        
                    <AjaxSettings> 
        
                        <telerik:AjaxSetting AjaxControlID="RadTreeView1">  
        
                            <UpdatedControls> 
        
                                <telerik:AjaxUpdatedControl ControlID="DetailsView1" /> 
        
                            </UpdatedControls> 
        
                        </telerik:AjaxSetting> 
        
                        <telerik:AjaxSetting AjaxControlID="DetailsView1">  
        
                            <UpdatedControls> 
        
                                <telerik:AjaxUpdatedControl ControlID="DetailsView1" /> 
        
                                <telerik:AjaxUpdatedControl ControlID="RadTreeView1" /> 
        
                            </UpdatedControls> 
        
                        </telerik:AjaxSetting> 
        
                    </AjaxSettings> 
        
                </telerik:RadAjaxManagerProxy>

Any ideas how I can improve ajax performance here? I'd rather not have to cascade drop-down lists for this hierarchical data.

Thanks in advance.
