Remove HTML tags from HTML markup string

It is an always challenge to remove HTML tags from html markup strings. We need to write lots of conditions and string operations like replace and substring etc..

In this post couple of functions will help to easily remove HTML tags from strings.

Code Block

               
              public static class HTMLTextHelper
              {
   
                public static string RemoveHtmlTags(string html)
                {
                    int pos = 0;
                    StringBuilder builder = new StringBuilder();
                    while (pos < html.Length)
                    {
                        if (html[pos] == '<')
                        {
                            pos = SkipTag(html, pos);
                            builder.Append(' ');
                        }
                        else builder.Append(html[pos++]);
                    }
                    return builder.ToString();
                }

    
                private static int SkipTag(string html, int pos)
                {
                    pos++;
                    while (pos < html.Length)
                    {
                        if (html[pos] == '"' || html[pos] == '\'')
                            pos = SkipString(html, pos);
                        else if (html[pos++] == '>')
                            break;
                    }
                    return pos;
                }


                private static int SkipString(string html, int pos)
                {
                    char quote = html[pos++];
                    while (pos < html.Length)
                    {
                        if (html[pos++] == quote)
                            break;
                    }
                    return pos;
                }
              }

Cod First using entity framework with MVC

Entity framework is support three different ways to interaction with database and develops application.

DB First: In DB First technique we first create database and then create .edmx file using entity framework.

Model First: In Model First technique we first create all data models using .edmx file of entity framework. After model design done we can create generate create script for that model and used to create database.

Code First: Code First is a most popular technique in now days for interact with database.

In Code First we create POCO (Plain Old CLR Object) models in code as a class object and entity framework convert that POCO model into database table.
So now we can create our entire database using POCO models as a class object and EF will convert that POCO models into database.
In this post I will demonstrate how, we can create database from POCO models using Entity Framework in MVC.

I am using MVC 3 and Entity Framework 4.3.1 version for demo code first. Entity Framework now available on nugget page also. Use install-package entityframework command for download entity framework.

Ok! Now let’s start demo. We will create one table for store project information

STEP: 1 Create POCO Model
Create MVC project for demo and install entity framework from nugget package manager.
Create class name with project in model.
By default EF will create tables with same name of model. We can set Table name attribute for set table name in database.

                [Table("ProjectData")]
                public class Project
                {
                    public int Id { get; set; }
                    public string Name { get; set; }
                    public string Description { get; set; }

                }
            

STEP: 2 Create Data Context Class
Create one class which inherits from System.Data.Entity.DBContext.
By default EF will create database using class name. we can set custom database name and connection strings if any then.
Now, Create property using DbSet[project] for project table.

                public class DATABContext : DbContext
                {
                    public DATABContext()
                        : base("ReportDB")
                    {
                        this.Database.CreateIfNotExists();
                    }
                    public DATABContext(string ConnectionString)
                        : base(ConnectionString)
                    {
                        this.Database.CreateIfNotExists();
                    }

                    public DbSet[Product] Products { get; set; }
                }
            

We have done almost using default settings for create database and tables from POCO. Now, next is how to use the models? We can use it in controller using following code.

                public class Default1Controller : Controller
                    {
                        private DATABContext db = new DATABContext();

                        //
                        // GET: /Default1/

                        public ViewResult Index()
                        {

                            return View(db.Products.ToList());
                        }
                   }
            

STEP: 3 Run Project
We have set all basic requirements for default database creation by Entity Framework. By default it use Sql Express server for create database and it will create ReportDB database with one table ProjectData.

STEP: 4 Use Existed Database
If we have already a database how can we use in CODE First technique?
It is actually easy and configurable. We can set database connection string by web.config file as well as by code.
By default DBContext class used connection string name of DBContext class.

                Connection string : 
                 
                    
                  
                
                By code we can set connection string using properties 

                Database.DefaultConnectionFactory = new SqlConnectionFactory("Data Source=RANMAL; Integrated Security=True; MultipleActiveResultSets=True");
                            

I Hope it will help!

KnockOut Js

In this article I will use knockoutjs for achieve MVVM patterns. Knockoutjs is a well known javascript library for create responsive, clean and rich interactive UI.

Knockout JS Features:

Bind model to UI: It is provide simple way to bind Model to direct UI
Dependency Trcking: It will automatically update UI base on changes in model data
Extensible: It is easy to write our custom method and behavior as per requirement of our application

MVVM (Model View View Model) design pattern for develop software. MVVM is specialize design pattern for presentation of Model in UI. It is targeted at modern UI development platforms which support Event-driven programming, such as HTML5, Windows Presentation Foundation (WPF), and Silverlight.
MVVM design pattern provide facility to develop software in a way the development of UI is totally separate of development of logic or model. MVVM is responsible to represent model on UI.

For set up visit http://github.com/downloads/SteveSanderson/knockout/knockout-2.0.0.js and download lasted knockoutjs and add in your solution.

Send Email in MVC using ActionMailer

Hello friends, happy Sunday:). Today’s post it about send email. Sending email is an easy task! This post it about how to send customize email base on model and view in MVC using controller and action method using Action Mailer.

Action Mailer is an open source library it is provide easy way to send email using MVC controller and action method, we can use view and model as an Email Template.

Action Mailer is now available on NuGet. We can download it using Visual Studio Package manager Consol using command : Install-Package ActionMailer

OR download using link :https://bitbucket.org/swaj/actionmailer.net/downloads/ActionMailer.Net.Mvc-v0.7.0.zip

Ok, now we are ready for simple demo of Action Mailer.

Step 1: SetUp Project
- Create MVC Application using VS 2010
- Install ActionMalier library using NuGet package
- Or download Action Mailer from above link and add reference of ActionMailer.Net.ddl and ActionMailer.Net.Mvc.ddl.

Step 2: Configuration
Action Mailer is use default smtp setting from web config file. We need to set smtp setting in project we.config file.
Open web.config file and add following code in file.

Step 3: Add Controller and Action
Now, First create entity Emailinfo in model.
Add new controller and action method in application. Second is inherit that controller from MailerBase.

            public class EamilInfo
            {
                public string Subject { get; set; }
                public string Body { get; set; }
                public string FromEamil { get; set; }
                public string ToEamil { get; set; }
            }

 public class MailController : MailerBase
    {
        public EmailResult SampleEamil(EamilInfo model)
        {
            To.Add(model.ToEamil);
            From = model.FromEamil;
            Subject = model.Subject;
            //CC.Add();
            //BCC.Add();
            //Attachments.Add();
            return Email("EmailTemplate",model);
        }

        public EmailResult SampleEamil1()
        {
            To.Add("testmail1@gmail.com");
            From = "testmail2@gmail.com";
            Subject = "Test";
            //CC.Add();
            //BCC.Add();
            //Attachments.Add();
            return Email("EmailTemplate1");
        }
    }

Step 4: Add Views
Using Action Mailer we can send both type email like only plain text and rich HTML email.
We can use Views as email template for send email.
Create view EmailTemplate.html.cshtml. In view name .html is refer the email will be send as HTML email. For send plain text email use EmailTemplate.text.cshtml.

using ActionMailer.Net
@model EmailController.Models.EamilInfo
@{
    Layout = null;
}



    


    

        Hi @Model.ToEamil,
        

        This is test email

        @Model.Body
        

        Thnaks & Regards, @Model.FromEamil
    

Step 5: Ready
All are ready, now just need to call method for send emails.
We can send email asynchronous and synchronous both way using ActionMailer.
Use Following code for send email.

            new MailController().SampleEamil(new EamilInfo
            {
                Body = "ActionMailer is awesome!",
                FromEamil = "ranmal.ratiya@gmail.com",
                ToEamil = "ranmal007@gmail.com",
                Subject = "Actionmailer Demo"
            }).Deliver(); 

            new MailController().SampleEamil(new EamilInfo
            {
                Body = "ActionMailer is awesome!",
                FromEamil = "ranmal.ratiya@gmail.com",
                ToEamil = "ranmal007@gmail.com",
                Subject = "Actionmailer Demo"
            }).DeliverAsync();

That is all, Hope it will help you!

Export TO Excel

Now is time to export to excel from generic list of any entity.

Start with two entities: 1) employee, 2) project

We need to export project and employee list as a excel file using same code.
Lest start with code.
First we need to create entities.

public class Employee
    {
        public int ID { get; set; }
        public string FirstName { get; set; }
        public string LastName { get; set; }
        public string Code { get; set; }
        public double Salary { get; set; }
    }

public class Project
    {
        public int ID { get; set; }
        public string Code { get; set; }
        public string Name { get; set; }
        public string Description { get; set; }
        public DateTime StatDate { get; set; }
        public DateTime EndDate { get; set; }
        public double Budget { get; set; }
 }

Now need to create some data access layer for create list of entities.

 public class DataAccess
    {
        public List[Employee] GetEmployees()
        {
            var lstemp = new List[Employee]();
            for (int i = 1; i <= 10; i++)
            {
                lstemp.Add(new Employee
                {
                    ID = i,
                    FirstName = "FirstName",
                    LastName = "LastName",
                    Code = "ECode" + i.ToString(),
                    Salary = 150.6 * i
                });
            }
            return lstemp;
        }
        public List[Project] GetProjects()
        {
            var lstprj = new List[Project]();
            for (int i = 1; i <= 10; i++)
            {
                lstprj.Add(new Project
                {
                    ID = i,
                    Budget = 124.5 * i,
                    Code = "PCODE" + i.ToString(),
                    Description = "Project Description",
                    EndDate = DateTime.Now.AddMonths(1),
                    StatDate = DateTime.Now,
                    Name = "Project"
                });
            }
            return lstprj;
        }
    }

Now last one, need to create generic class for export list to excel

public static class Export[T] where T : class
    {
        public static void ExcelExport(string name, List[T] objlist)
        {

            HttpContext.Current.Response.Clear();
            HttpContext.Current.Response.
            AddHeader("content-disposition", 
            string.Format("attachment; filename={0}", name + ".xls"));
            HttpContext.Current.Response
            .ContentType = "application/ms-excel";

            using (var sw = new StringWriter())
            {
                using (var htw = new HtmlTextWriter(sw))
                {
                    //  Create a form to contain the List
                    var table = new Table();
                    table.Style.Add(HtmlTextWriterStyle.BorderStyle, 
                                    "solid 1px #000");
                    var row = new TableRow();
                    var firstOrDefault = objlist.FirstOrDefault();
                    if (firstOrDefault != null)
                        foreach (var hcell in firstOrDefault.GetType()
                           .GetProperties().Select(proinfo => new TableHeaderCell
                                                        { Text = proinfo.Name }))
                        {
                            hcell.Style.Add(HtmlTextWriterStyle
                            .BackgroundColor, "#d0d0d0");
                            hcell.Style.Add(HtmlTextWriterStyle
                            .BorderColor, "#000000");
                            row.Cells.Add(hcell);
                        }
                    table.Rows.Add(row);

                    //  add each of the data item to the table
                    foreach (var emp in objlist)
                    {
                        var row1 = new TableRow();
                        foreach (var cell in emp.GetType()
                       .GetProperties().Select(prop => new TableCell 
                        { Text = prop.GetValue(emp, null).ToString() }))
                        {
                            cell.Style.Add(HtmlTextWriterStyle
                            .BackgroundColor, "#FFF");
                            cell.Style.Add(HtmlTextWriterStyle
                           .BorderColor, "#000000");
                            row1.Cells.Add(cell);
                        }
                        table.Rows.Add(row1);

                    }

                    //  render the table into the htmlwriter
                    table.RenderControl(htw);

                    HttpContext.Current.Response.Write(sw.ToString());
                    HttpContext.Current.Response.End();
                }
            }
        }
    }

Ok, we have done. Now just need to use above export class for export list using following code.

            var objDBContext = new DataAccess();
            grdproject.DataSource = objDBContext.GetProjects();
            grdproject.DataBind();
            grdemployee.DataSource = objDBContext.GetEmployees();
            grdemployee.DataBind();
       
            Export[Project].ExcelExport("MyProjects", new DataAccess().GetProjects());
            Export[Employee].ExcelExport("CompanyEmployee", new DataAccess().GetEmployees());

That's all I have done! Thank you for your attention. For more details you can comments on post or can contact me directly by my contact info. I hope you like my blog and find it usefully for you.

That's ALL ! I hope it will help you!!!
