Managed Code and UnManaged Code

-
Managed Code is produced by (vb.net,c#,j#) .net framework language, which is under the control of CLR (Common Language Runtime).Garbage collector run automatically in managed code.

Unmanaged Code is produced by third party language such as C++ can be used to write such applications, which does not run under the control of CLR.Garbage collector will not run in case of unmanaged code.

Examples of Unmanaged code are Access low-level functions of the operating system. Background compatibility with code of VB, ASP and COM.

ASP.NET MVC: Benefits

-
Back to Home 1) Separation of Concerns - Model: Model is associated with Views and a Controller (Bussiness Entity) - View: Views are the components that display on User Interface (UI) - Controller: Controller is an input control 2) Each component has one responsibility - SRP – Single Responsibility Principle - DRY – Don’t Repeat Yourself 3) More easily testable - TDD – Test-driven development 4) Helps with concurrent development - Performing tasks concurrently - One developer works on views - Another works on controllers 5) Replace any component of the system - Interface-based architecture 6) Almost anything can be replaced or extended - Model binders (request data to CLR objects) - Action/result filters (e.g. OnActionExecuting) - Custom action result types - View engine (Razor, WebForms, NHaml, Spark) - View helpers (HTML, AJAX, URL, etc.) 7) REST-like URLs - /accounts/details

Introduction to ASP.Net MVC

Back to Home Model-View-Controller (MVC) is a software architecture pattern. Originally formulated in the late 1970s by Trygve Reenskaug as part of the Smalltalk, MVC architecture works on code reusability and separation of concerns. It was originally developed for desktop Then adapted for internet applications. The Model is the application object, the View is UI presentation, and the Controller defines the way the user reacts to user input from UI. MODEL: - Set of classes that describe the data we are working with - Rules for how the data can be changed and manipulated - May contain data validation rules - Often encapsulate data stored in a database as well as the code used to manipulate the data Most likely a Data Access Layer of some kind VIEW: - Defines how the application’s user interface (UI) will be displayed - Support master views (layouts)  - Support sub-views (partial views or controls) - Web: Template to dynamically generate HTML CONTROLLE

Paged Data Source - Custom Paging

-
PagedDataSource , is a class that encapsulates the paging related properties for data-bound controls such as DataGrid, GridView, DataList, DetailsView and FormView that allow it to perform paging. And this article is going to combine both DataList control and PagedDataSource class to explain dynamic or custom paging methods for Asp.Net developers. protected void Page_Load( object sender, EventArgs e) { try { if (!IsPostBack) { LoadPhoto(); } } catch (Exception Exc) { HandleException = Exc; } } // LoadPhoto Function private void LoadPhoto() { PagedDataSource objPhotoPage = new PagedDataSource(); objPhotoPage.AllowPaging = true ; SOBLImageGallery _SOBLImageGallery = new SOBLImageGallery(); DataSet dsImageGallery = _SOBLImageGallery.Select6Records( new SOENTImageGallery()); if (dsImageGallery != null && dsImageGallery.Tables.Count > 0 && dsImageGallery.Tables[0].

SOLID Principles with C#

-
SOLID Principles are coding standards that all developers should have a clear concept for developing software in a proper way to avoid a bad design. S - Single Responsibility Principle (SRP): A class should have one, and only one, a reason to change In Single Responsibility Principle Each class and module should focus on a single task at a time Everything in the class should be related to that single purpose There can be many members in the class as long as they related to the single responsibility With SRP, classes become smaller and cleaner Code is less fragile  Here  UserAccount  class created which have below operations like, Login, Register, LogError and Send Mail. According to SRP, ideally, LogError and SendEmail are should not be part of  UserAccount  operations.      public class UserAccount     {         public bool Login( string username, string password)         {             //Login varification code             return true ;

Auto Sequence Number in Grid Control with Paging

-
we are going to see how to generate sequence number (row number) in DataGrid. To generate sequence number, we will use the DataGridItem’s ItemIndex property. But For example if we are going to second page with Pagesize 3, then sequence number should start from 4. Code snippet for implementing this method is... < asp:DataGrid id ="DataGrid1" runat ="server" PagerStyle-Mode ="NumericPages" PageSize ="10" AutoGenerateColumns ="False" AllowPaging ="True" > < Columns > < asp:templatecolumn headertext ="Row Number" > < itemtemplate > <% # (DataGrid1.PageSize*DataGrid1.CurrentPageIndex)+ Container.ItemIndex+1 %> </ itemtemplate > </ asp:templatecolumn > < asp:boundcolumn runat ="server" Da
