ASP.NET MVC.

  1. 1. BY ME
  2. 2.  Model: Is creating classes and writing the business logic and can be connected to a database.  View: Is the design [UI: User Interface].  Controller: Helps to communicate between model from view.
  3. 3.  From View, user gives input.  The input is given to the Controller.  The Controller then passes the data to a Model.  The Model checks the data and return back to the View.
  4. 4.  When we run the program , by default it invokes Index method.  The Index method then invokes the corresponding View.  Every View has the extension as .cshtml [Combination of C# and HTML code].
  5. 5.  Every action method should be associated with a View.  By default, the View name and Controller name will be same.  If the View name and Controller name is different, return view("viewname")
  6. 6.  ViewData: Is used to store data as a key-value pair. It stores a single data at a time.  Syntax: ViewData["key"]=value; where key is a unique name. It is user- defined.
  7. 7.  ViewBag: Is used to store the data by giving a name.  Is used to store more than one data.  Syntax: ViewBag.name=value;
  8. 8.  The syntax used in view page is a combination of C# code and HTML code is called as Razor Syntax. ie: [C#,HTML ] or [VB,HTML].  Extension of the file is .cshtml or .vbhtml.
  9. 9.  @ Character symbol has to used to access the C# code.  C# code are case-sensitive.  Strings must be in double quotes.  Statement must be in semicolon.  Variables can be declared using var keyword.
  10. 10.  The views which do not have a complete code but it contains a code , which can be reused by multiple views is called Partial Views.  It has to be created inside a shared folder.  The name of the partial view should start with "_" Character.
  11. 11.  When we create the view, we should choose option as "Create as partial view".  If we want to call the partial view from any of our actual views, @Html.Partial("_Myview")
