    Hi Experts, 

    I have written an Action with return type as "FileResult" which takes Parameter as ID. For some ID the file may not exists. It downloads the file if exists. But if no file exists then I want to show a message on the screen that "File does not exists" and the control should stay on the same page. I am using Asp.Net MVC 5 framework

    How can I achieve the same ?

    This is not an Asp.NET forum, you should direct them to the Mike's suggested link but you can use a Viewbag for the simplest solution and show that value in your view. 

    public FilePathResult YourMethod(int id)
{
          if(!database.Files.Any(x=>x.Id==id) 
    	{
    		TempData["yourMessage"] = "File does not exist!";
    		return RedirectToView("CurrentView"); // change the name with the view you want to be
    	}	
}

    In your view add the tempData like this for example: 

    <div>@TempData["yourMessage"]  </div>
