Implement iCalendar Export to Outlook in Scheduler Appointment Context menu

[codispdp]

I am trying to put the iCalendar export functionality 
http://demos.telerik.com/aspnet-ajax/scheduler/examples/export/defaultvb.aspx
into the Appointment context menu
http://demos.telerik.com/aspnet-ajax/scheduler/examples/contextmenu/defaultvb.aspx

Has anyone accomplished this yet and do they have a code snippet?

Thanks

Hi codispdp,

That shouldn't be hard to achieve. SImply handle AppointmentContextMenuItemClicking like so:

protected void RadScheduler1_AppointmentContextMenuItemClicking(object sender, AppointmentContextMenuItemClickingEventArgs e)
   {
       if (e.MenuItem.Value == "Export")
       {
           WriteCalendar(RadScheduler.ExportToICalendar(e.Appointment));
       }
   }
   private void WriteCalendar(string data)
   {
       HttpResponse response = Page.Response;
       response.Clear();
       response.Buffer = true;
       response.ContentType = "text/calendar";
       response.ContentEncoding = Encoding.UTF8;
       response.Charset = "utf-8";
       response.AddHeader("Content-Disposition", "attachment;filename=\"RadSchedulerExport.ics\"");
       response.Write(data);
       response.End();
   }

Thanks for your suggestion, I am using a RadAjaxManager on the page so the client code works using

function Export(sender, e)
            {
                $find("<%= RadAjaxManager1.ClientID %>").__doPostBack(sender.name, "");
            }

I tried to implement the same code you suggested and received a SYS.Webforms.PageMangerParserErrorException because the response was trying to be modified. Is the a way to use the RadAjaxManager RaisePostBackEvent on the server side to mimic the same functionality as

 Protected Sub RadScheduler1_AppointmentCommand(ByVal sender As Object, ByVal e As Telerik.Web.UI.AppointmentCommandEventArgs) Handles RadScheduler1.AppointmentCommand
        If e.CommandName = "Export" Then
            WriteCalendar(RadScheduler.ExportToICalendar(e.Container.Appointment))
        End If
    End Sub

Hi codispdp,

Indeed, exporting appointments requires a real postback. The good news is that RadAjaxManager's client API allows for easy solution to this problem. The idea is to set a flag in OnClientAppointmentContextMenuItemClicking and use this flag to disable ajax in OnRequestStart. Here is an example:

<script type="text/javascript">
       var ajaxFlag = true;
       function OnClientAppointmentContextMenuItemClicking(sender, args) {
           if (args.get_item().get_text() == "Export") {
               ajaxFlag = false;
           }
       }
       function OnRequestStart(sender, eventArgs) {
           eventArgs.set_enableAjax(ajaxFlag);
           ajaxFlag = true;
       }
   </script>
   <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
       <AjaxSettings>
           <telerik:AjaxSetting AjaxControlID="RadScheduler1">
               <UpdatedControls>
                   <telerik:AjaxUpdatedControl ControlID="RadScheduler1" />
               </UpdatedControls>
           </telerik:AjaxSetting>
       </AjaxSettings>
       <ClientEvents OnRequestStart="OnRequestStart" />
   </telerik:RadAjaxManager>
   <telerik:RadScheduler ID="RadScheduler1" runat="server" OnClientAppointmentContextMenuItemClicking="OnClientAppointmentContextMenuItemClicking"
       OnAppointmentContextMenuItemClicking="RadScheduler1_AppointmentContextMenuItemClicking"
       Culture="fa-IR">
       <AppointmentContextMenus>
           <telerik:RadSchedulerContextMenu ID="RadSchedulerContextMenu1" runat="server">
               <Items>
                   <telerik:RadMenuItem Text="Export">
                   </telerik:RadMenuItem>
               </Items>
           </telerik:RadSchedulerContextMenu>
       </AppointmentContextMenus>
   </telerik:RadScheduler>
