You can have your action method returns the HTML for your badge, which includes the data(warning number) as well.

public class WarningController : Controller
{
   public ActionResult Badge()
   {
      int contWarning = 10; // temp hard coded value for demo;
      // Replace the hard coded value 
      // with your existing code to get the data from database
      return PartialView("Badge",contWarning);
   }
}

Now in your Badge.cshtml, which is storngly typed to int type, render the HTML you want.

@model int
<span class="badge">
    @Model
</span>

Now in your layout(_Layout.cshtml), call this render the output of this Badge action method using the Html.Action method.

 @Html.Action("Badge","Warning")

Make sure you are returning a partial view (which does not have it's own layout) using PartialView instead of View method. If your Badge action method is returning a view which has the same layout file, that will cause an infinite loop and you will get the StackOverflow exception.
