  How to generate HTML from void()

  Dec 03, 2012 05:27 PM|LINK

  Hello,

  I have simple CSHTML page with this code. Why "foreach" doesn't generate anything? I have this problem also in another situations - can't generate html from within function. 

  @functions{
   
      void WriteArticles() {
          var db = Database.Open("Data"); 
          var selectQueryString = "SELECT * FROM Articles";
          var data = db.Query(selectQueryString);
   
          foreach(var row in data){
              Html.Raw("<p>"+row.Name+"</p>");
          }
          
      }
  }
  @{
  WriteArticles();
  }

  Vladimir

  You should use a helper, not a function to render HTML: http://www.mikesdotnetting.com/Article/173/The-Difference-Between-@Helpers-and-@Functions-In-WebMatrix

  @helper WriteArticles() {
      var db = Database.Open("Data");
      var selectQueryString = "SELECT * FROM Articles";
      var data = db.Query(selectQueryString);
      foreach(var row in data){
          <p>@row.Name</p>
      }
  }
  @WriteArticles()
