    Hello Telerik Team,

    I am having on RAD treeview inside inside RadAjaxPanel to handle treeview(on demand loading with webservice) events on server with callbak.Now I want to do some processing on server in "OnContextMenuItemClick" event after which in certain condition I need to call Javascript function where I can take confirmation from user regarding furthure action , if user say "yes" then again I want to go on server and execute on method.
    for second server call I am using RadAjaxManagerProxy  as my master page already have RadAjaxManager. my RadAjaxManagerProxy  setting is as follow

     

     

    <telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy" runat="server" > 
                            <AjaxSettings> 
                                <telerik:AjaxSetting AjaxControlID="RadTreeView">  
                                    <UpdatedControls> 
                                        <telerik:AjaxUpdatedControl ControlID="RadTreeView" /> 
                                        <telerik:AjaxUpdatedControl ControlID="IsShared" /> 
                                    </UpdatedControls> 
                                </telerik:AjaxSetting> 
                            </AjaxSettings>      
                        </telerik:RadAjaxManagerProxy> 


    I am delegating AJAX request in page load to call my method on server .

     

    RadAjaxManager manager = RadAjaxManager.GetCurrent(Page);  
    manager.AjaxRequest += new RadAjaxControl.AjaxRequestDelegate(RadAjaxManager_RadAjaxRequest); 


    "RadAjaxManager_RadAjaxRequest" method is called and I am doing all my processing inside it. Up till now things are fine but the Issue is I want to update selected treeview node after performing my operation which is somthing not working.

    Can you guid me how I can update selected node in treeview after performing my operation from "RadAjaxManager_RadAjaxRequest"?

    If possible give me some running example which can give me clear understanding.

    Thanks in advance,
    Frank

    Hi, 
    I have the same question. In general how should I send the response back to client after some processing in RadAjaxManager_RadAjaxRequest event handler ?
    I appreciate fast response.

    Hi Ali,

    You can handle on client OnResponseEnd event which is fired when a response from the server is processed.

    Give it a try and let me know if it helps.
