ASP.NET MVC Hosting 6 Tips for ASP.NET MVC Model Binding
Model binding in the ASP.NET MVC framework is simple. Your action methods need data, and the incoming HTTP request carries the data you need. The catch is that the data is embedded into POST-ed form values,mens luxury watches, and possibly the URL itself. Enter the DefaultModelBinder, which can magically convert form values and route data into objects. Model binders allow your controller code to remain cleanly separated from the dirtiness of interrogating the request and its associated environment. Tip 1 : Prefer Binding Over Request.Form If you are writing your actions like this .. [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create {     Recipe recipe = new Recipe;     recipe.Name = Request.Form["Name"];     // ... return View; } .. then you are doing it all wrong. The model binder can save you from using the Request and HttpContext properties – those properties make the action harder to read and harder to test. One step up would be to use a FormCollection parameter instead: public ActionResult Create(FormCollection values) {     Recipe recipe = new Recipe;     recipe.Name = values["Name"];      // ... return View; } With the FormCollection you don't have to dig into the Request object, and sometimes you need this low level of control. But, if all of your data is in Request.Form,android watches, route data, or the URL query string,mens designer watches, then you can let model binding work its magic: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create(Recipe newRecipe) {     // ... return View; } In this example,swiss army watches, the model binder will create your newRecipe object and populate it with data it finds in the request (by matching up data with the recipe's property names). It's pure auto-magic. There are many ways to customize the binding process with "white lists",timex expedition watch, "black lists", prefixes,mens watch brands, and marker interfaces. For more control over when the binding takes place you can use the  UpdateModel and TryUpdateModel methods. Tip 2 : Custom model binders Model binding is also one of the extensibility points in the MVC framework. If you can't use the default binding behavior you can provide your own model binders,casio watches, and mix and match binders. To implement a custom model binder you need to implement the IModelBinder interface. There is only method involved - how hard can it be? public interface IModelBinder {     object BindModel(Controller Context controllerContext,bulova watch reviews,                      ModelBindingContext bindingContext); } Once you get neck deep into model binding, however, you'll discover that the simple IModelBinder interface doesn't fully describe all the implicit contracts and side-effects inside the framework. If you take a step back and look at the bigger picture you'll see that model binding is but one move in a carefully orchestrated dance between the model binder, the ModelState,Watches Online, and the HtmlHelpers. You can pick up on some of these implicit behaviors by reading the unit tests for the default model binder. If the default model binder has problems putting data into your object,Swiss Watches, it will place the error messages and the erroneous data value into ModelState. You can check ModelState.IsValid to see if binding problems are present, and use ModelState.AddModelError to inject your own error messages. Both the controller action and the view can look in ModelState to see if there was a binding problem. The controller would need to check ModelState for errors before saving stuff into the database, while the view can check ModelState for errors to give the user validation feedback. One important note is that the HtmlHelpers you use in a view will require ModelState to hold both a value (via ModelState.SetModelValue) and the error (via AddModelError) or you'll have runtime errors (null reference exceptions). The following code can demonstrate the problem: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create(FormCollection Form0 {     // this is the wrong approach ...     if (Form["Name"].Trim.Length == 0)         ModelState.AddModelError("Name", "Name is required");     return view; }  The above code creates a model error without ever setting a model value. It has other problems,invicta watch review, too,Watches Online Shop, but it will create exceptions if you render the following view.  &lt;%= Html.TextBox("Name", Model.Name) %&gt;  Even though you've specified Model.Name as the value for the textbox, the textbox helper will see the model error and attempt to display the "attempted value" that the user tried to put in the model. If you didn't set the model value in model state you'll see a null reference exception.  Tip 3 : Custom Mode Binding via Inheritance  If you've decided to implement a custom model binder, you might be able to cut down on the amount of work required by inheriting from DefaultModelBinder and adding some custom logic. In fact, this should be your default plan until you are certain you can't subclass the default binder to achieve the functionality you need. For example, suppose you just want to have some control over the creation of your model object. The DefaultModelBinder will create object's using Activator.CreateInstance and the model's default constructor. If you don't have a default constructor for your model, you can subclass the DefaultModelBinder and override the CreateModel method. Tip 4 : Using Data Annotations for Validation .NET 3.5 SP1 shipped a System.ComponentModel.DataAnnotations assembly that looks to play a central role as we move forward with the .NET framework. By using data annotations and the DataAnnotationsModelBinder, you can take care of most of your server-side validation by simply decorating your model with attributes. public class Recipe {     [Required(ErorrMessage="We need a name for this dish.")]     [Regular [removed]"^Bacon")]     public string Name { get; set; }     // ... }  The DataAnnotationsModelBinder is also a great sample to read and understand how to effectively subclass the default model binder.  Tip 5 : Recognize Binding and Validation As Two Phases  Binding is about taking data from the environment and shoving it into the model, while validation is checking the model to make sure it meets our expectations. These are different different operations, but model binding tends to blur the distinction. If you want to perform validation and binding together in a model binder, you can – it's exactly what the DataAnnotationsModelBinder will do. However, one thing that is often overlooked is how the DefaultModelBinder itself separates the binding and validation phases. If all you need is simple property validation,mickey mouse watch, then all you need to do is override the OnPropertyValidating method of the DefaultModelBinder. Tip 6 : Binders Are About The Environment Earlier we said that "model binders allow your controller code to remain cleanly separated from the dirtiness of interrogating the request and its associated environment". Generally, when we think of binder we think of moving data from the routing data and posted form values into the model. However,timex watches, there is no restriction of where you find data for your model. The context of a web request is rich with information about the client.

The Detox Diet Fad by San Diego Boot Camp
,digital watch There is nothing proven that these detoxes and cleanses really do what they aim to do. Furthermore,bulova accutron watches, the human body is designed to cleanse all by itself. The intestines contain the good kinds of bacteria that are actually beneficial for the body. When you feed your body healthy nutrients,Cheap Watches For Sale, it can detox itself.

Do Detox Diets Work?

The best way to truly detox your body is to change eating habits by adding nutritient-rich whole foods and avoiding processed foods. This is much more effective than doing something drastic like living off lemon juice.

By eating a healthy,timex watches, balanced diet the body will detox all on its own. It can be compared to quitting drinking or smoking. As soon as the unhealthy habits stop,mens designer watches, the body will begin detox from all the toxins.

Why then,swiss army watches, do people lose weight when doing a cleanse or detox diet? The fact is - the weight people are losing from a detox diet is mostly just water weight.

Many people try to lose weight and cleanse their bodies through the popular ‘detox' type diets. Many of these diets include eating only certain fruits and/or vegetables and drinking laxative teas. People who do these diets may report weight loss and the feeling of cleansing their bodies. But are these really good for the body?

What happens after the detox diet?

Most people gain the weight right back,Cheap Watches For Men, especially if they go right back to eating unhealthy foods. The benefits they may have gleaned from eating fresh fruits and veggies don't last unless they are maintained.

One of the more popular detoxes is the "master cleanse" in which people only drink lemon juice with cayenne pepper and maple syrup. Because people on the master cleanse are not eating solid foods,Watch, the lemon juice acts as a natural laxative causing water weight loss.

Instead of a 10-day detox diet people might think about truly getting rid of habitual toxins such as highly processed foods and unhealthy foods for good.

Another potential reason people may lose weight on a detox diet is because they are in the mindset of health and wellbeing: in other words – the placebo effect.
