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, ...
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...

Applying Dynamic Themes to Web Page (.aspx) in ASP.NET Themes and Skins. The themes and skins features in ASP.NET 2.0 allow for easy customization of your site's look-and-feel. You can define style information in a common location called a "theme", and apply that style information globally to pages or controls in your site. Like Master Pages, this improves the maintainability of your site and avoid unnecessary duplication of code for shared styles. protected void Page_PreInit( object sender, EventArgs e) { Page.Theme = Session[ "Theme" ] as string ?? "Theme1" ; } protected void Page_Load( object sender, EventArgs e) { } protected void Button1_Click( object sender, EventArgs e) { if (Session[ "Theme" ] != null ) { if (Session[ "Theme" ].ToString() == "Theme1" ) Session[ "Theme" ] = "Theme2" ; else Session[ "Theme" ] = "Theme1...
Send Email using Gmail SMTP server-ASP.NET What is an SMTP server? (pronounced as separate letters) Short for S imple M ail T ransfer P rotocol, a protocol for sending e-mail messages between servers. Most e-mail systems that send mail over the Internet use SMTP to send messages from one server to another; the messages can then be retrieved with an e-mail client using either POP or IMAP. In addition, SMTP is generally used to send messages from a mail client to a mail server. This is why you need to specify both the POP or IMAP server and the SMTP server when you configure your e-mail application. Let's see one example in ASP.NET 2.0 (Web Application) In WebMailSend.aspx.cs file You have to import this namespace for MailMessage. using System.Net.Mail; protected void btnSend_Click( object sender, EventArgs e) { try { MailMessage mail = new MailMessage(); mail.IsBodyHtml = true ; mail.To.Add(txtEmail.Text); mail.Subject = txtSubject.Text; mail....

I was facing some issue to update excel cell which was depended on some formula, I need to change 'Comparison_Rate_Calculator' by Programming and need to read Calculated value by formula '=+HLOOKUP(C3,Workings!$D$1:$AJ$2,2,FALSE)' over 'Comparison_Rate_Calculator_Values' column. I didn't get calculated value even i was able to change 'Comparison_Rate_Calculator' column's value. So I got solutions by refreshing Excel WorkSheet and Here is the Solutions. File: Web.Config < connectionstrings > < add name = " xls " connectionstring = " Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\AshvinWorkspace\POCs\ReadExcelSheet\ReadExcelSheet\Files\HLComparisonRateCalculator.xls;Extended Properties=Excel 8.0 " > </ add > </ connectionstrings > File: Default.aspx.cs public partial class _Default : System.Web.UI.

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 CONTR...
