Finding the execution time of a action in MVC 3 using global action filters.

Today i found a very interesting issue while working with global action filters in MVC,we can measure the execution time of the  action with the help of "OnResultExecuting" and "OnResultExecuted" method in the action filter attribute.

Here we can track the user activities and logs globally in global action filter attribute.So each and every request can be captured in action filter attribute.

Here is the step by step explanation of how to implement global action filter with example of measuring excution time of a action.

public class StopwatchAttribute : ActionFilterAttribute

{

    private readonly Stopwatch _stopwatch;

    public StopwatchAttribute()

    {

        _stopwatch = new Stopwatch();

    }

    public override void OnActionExecuting(ActionExecutingContext filterContext)

    {

        _stopwatch.Start();

    }

    public override void OnActionExecuted(ActionExecutedContext filterContext)

    {

        _stopwatch.Stop();

        var httpContext = filterContext.HttpContext;

        var response = httpContext.Response;

        var elapsed = _stopwatch.Elapsed.ToString();

        // Works for Cassini and IIS

        //response.Write(string.Format("<!-- X-Stopwatch: {0} -->", elapsed));  

        // Works for IIS

        response.AddHeader("X-Stopwatch", elapsed);

    }

}  



Now register these filter in gloabal.asax aplication_Start

protected void Application_Start()

{

    AreaRegistration.RegisterAllAreas();

    GlobalFilters.Filters.Add(new StopwatchAttribute());

    RegisterGlobalFilters(GlobalFilters.Filters);

    RegisterRoutes(RouteTable.Routes);

}

Now create the controller with a sample action 

public class HomeController : Controller
{
    public ActionResult Index()
    {
        ViewModel.Message = "Welcome to ASP.NET MVC!";
 
        return View();
    }
 
    public ActionResult About()
    {
        return View();
    }
}






Now run your mvc application, when action executing it will starts the timer on 
"OnActionExecuting" and stops the timmer in "OnActionExecuted".and displays the 
execution time in responce header or if you can write it in responce.write like 
below.









Here if you want too track or log the user activities you can use




public class UserActivityAttribute : ActionFilterAttribute

{

  public override void OnResultExecuting(ResultExecutingContext filterContext)

  {

    if ((filterContext.Result is RedirectToRouteResult) &&

        (filterContext.RequestContext.HttpContext.Request.RequestType == "POST"))

    {

      var originController = filterContext.RouteData.Values["controller"].ToString();

      var originAction = filterContext.RouteData.Values["action"].ToString();

 

      if (originAction == "Create")

      {

 

      }

    }

    base.OnResultExecuting(filterContext);

  }

}

Asp.net MVC client side model validations

In this post am going to explain you about client side model validations in asp.net MVC
in MVC 2.0 or avove versions  we have bunch of features that we can enable many features at client side
in that one of the most important and useful was model validation at client side with help of unobtrusive validation jquery.

with this unobtrusive jquery we can do the validations based on the data annotations which are applied on the model classes.

In order to enable client side model validation we need a two jquery references see the image bellow 

in MVC 2.0 we need to add these two references 



If you are in MVC 3.0 or avove use
                       "~/Scripts/jquery.unobtrusive.js",
                        "~/Scripts/jquery.validate.js"

here is the step by step implementation for client side model validation see bellow
