Dear all,

Am a newbie in umbraco and razor. Am having an issue with in displaying images for slideshow . It gives me the following error Cannot get MediaById without an id . Please find my code below and many thanks for your kind responses.

P.S am using umbraco v 4.7.0 (Assembly version: 1.0.4868.25116)

@using umbraco.MacroEngines;
@using umbraco.cms.businesslogic.media; 

@inherits umbraco.MacroEngines.DynamicNodeContext 

@{
  
  List<DynamicNode> upcomingEvents= Model.AncestorOrSelf(1).Descendants("SportEvents").Where("!umbracoNaviHide").Where("startEventDate >= DateTime.Now.Date").OrderBy("startEventDate descending").Items;
  
  
  @Html.Raw("slides : [")
   foreach( DynamicNode events in upcomingEvents)
      {

       var title =@events.Name;
       var mediaIdFolder   = @events.GetProperty("eventPhotoGallery").Value.ToString();
       var mediaFolder = @Library.MediaById(2647); 
       var imgpath = @mediaFolder.Children.First().HasValue("umbracoFile") ? @mediaFolder.Children.First().umbracoFile : "/media/60612/dummy.jpg";     
        
       var img="{image:";
       var eventName =",title:";
       var eventDate =",dateEvent:";
       var closingslide="},";
       var description= @events.GetProperty("eventDescription").Value.ToString();
       
       var startEventDate= @library.FormatDateTime(@events.GetProperty("startEventDate").Value.ToString(),"dd/MM/yyyy"); 
       var endEventDate = @library.FormatDateTime(@events.GetProperty("endEventDate").Value.ToString(),"dd/MM/yyyy"); 
      
     
       
        
      
      
       var slides = @img +"\'"+@imgpath+"\'"+@eventName+"\'"+@title +"\'"+@eventDate+"\'"+@startEventDate+"\'"+@closingslide;     
        @Html.Raw(@slides)
      }
  
  @Html.Raw("]")
}
