Differences between a Structure and Class

1. Clas s is Reference types and Structure is Value type.   2. Clas s supports an Inheritance where as Structure not.   3. Classes are usually used for large amounts of data, whereas Structure are usually used for smaller amount of data.   4. When we instantiate a class, memory will be allocated on the heap and when Structure gets initiated it gets memory on the stack. 5. Classes can have explicit parameter less constructors. But Structure doesn't have this. 6. Classes can be garbage collector because garbage collector works on heap memory . structures can not be garbage collector so no memory management.

Run time polymorphism (Late binding or dynamic binding)   Example: overridden methods that are called using base class object.

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...

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 ...
