Restful ASP.NET MVC

► Uygulamamızda PUT ve DELETE metotlarını destekleyebilir miyiz?

► HTML formları sadece GET ve POST destekler !!!

<input name="X-HTTP-Method-Override" type="hidden" value="DELETE" />

Asynchronous Actions

► Uzun sürecek bir işlem için IIS thread’ini meşgul etmemek performansı arttırır.

► Kullanıcı açısından değişiklik olmaz !!!

► Controller yerine AsyncController sınıfından türetmek gerek – public void ActionNameAsync(...) – public ActionResult ActionNameCompleted(...)

Default Editor Templates

► Boolean – check-box or 3-state drop-down ► Collection – iterate and show editor (with name style “*n+”)

► Decimal – text box (with formatting) ► HiddenInput – hidden input ► MultilineText – text area ► Object – edit all simple properties ► Password – text box (password) ► String, Text – text box

Default Display Templates

► Boolean – disabled checkbox or 3-state drop-down

► Collection – iterate and display ► Decimal – encoded text (with formatting) ► EmailAddress – auto-linked (with mailto:) ► HiddenInput – encoded text ► Html – unencoded text ► Object – show all simple properties ► String, Text – encoded text ► Url – auto-linked
