Html Raw of Asp.net MVC 3 with Razor view engine

Today, I'm posting about HTML Raw of MVC3 Razor View engine.

HtmlString IHtmlString and HttpUtlity.HtmlEncode in ASP.NET 4 are fantastic features.

Saving Content in Database, retrieve it dynamically on Front end page that is absolutely nice.

HtmlHelper.Raw Method wraps HTML markup using the IHtmlString class, which renders unencoded HTML.

   1:  public IHtmlString Raw(

2: string value 3: )

   1:  @{ var para = "<p>I am a parargraph</p>";}

   2:  @Html.Raw(para)

LinkedList(Of T) Class C#

Today, I'm posting to about LinkedList class. LinkedList is one of System.Collections.Generic collection classes.

What LinkedList class can do:
You can remove nodes and reinsert them, either in the same list or in another list, which results in no additional object allocated on the heap. LinkedList accepts null value.

Please note: LinkedList class doesn't support chaining, splitting, cycles or other features that can leave the list in inconsistent state. The list remains consistent on a signle thread. The Linkedlist supports multithread read.

Please see the following examples:

   1:  using System;

   2:  using System.Text;

   3:  using System.Collections.Generic;

   4:   

   5:  public class Example

   6:  {

   7:      public static void Main()

   8:      {

   9:          // Create the link list.

  10:          string[] words =

  11:              { "the", "fox", "jumped", "over", "the", "dog" };

  12:          LinkedList<string> sentence = new LinkedList<string>(words);

  13:          Display(sentence, "The linked list values:");

  14:          Console.WriteLine("sentence.Contains(\"jumped\") = {0}",

  15:              sentence.Contains("jumped"));

  16:   

  17:          // Add the word 'today' to the beginning of the linked list.

  18:          sentence.AddFirst("today");

  19:          Display(sentence, "Test 1: Add 'today' to beginning of the list:");

Is Razor or XSLT better for my project?

I've read an very good article about XSLT and RAZOR. Some people think XSLT is better when you are using Multiple templates.

I don't agree with that. For me, Xslt is good for only static html pages. (no server codes). When you need to use server code, it's a lot difficult to control with XSLT.

XSLT or Razor would help to provide a separation of concerns where the original XML or response represents your model, the XSLT or 'Razor view' represents your view. I'll leave the controller out for this example. The initial design proposal recommends XSLT, however I suggested the use of Razor instead as a more friendly view engine.

These are the reasons I suggested for Razor (C#):

• Easier to work with and build more complicated pages.
• Can easily produce non-*ML output, eg csv, txt, fdf
• Less verbose templates
• The view model is strongly typed, where XSLT would need to rely on convention, eg boolean or date values
• Markup is more approachable, eg nbsp, newline normalization, attibute value normalization, whitespace rules
• Built in HTML helper can generate JS validation code based on DTO attributes
• Built in HTML helper can generate links to actions

And the arguments for XSLT over razor were:

• XSLT is a standard and will still exist many years into the future.
• It is hard to accidentally move logic into the view
• Easer for non programmers (which I don't agree with).
• It's been successful in some of our past projects.
• Data values are HTML-encoded by default
• Always well formed

So I'm looking for aguments on either side, recommendations or any experience making a similar choice?

MVC 3 Razor C# View Engine adding

As a OOD web developer, I like to group usercontrols, pages to related folders.
In MVC 3, Default Search view engine works like the following:

If user controls, the View engine finds under View folder OR Shared folder only.

Here is a problem:

If I created a folder under shared folder and your user control having in that folder, MVC ViewEngine couldn't find the correct user control via embedded usercontrol's page.

.Net throws this error.




But in MVC, every class that integreated in MVC you can extend as your custom requried.

Here is an example that I've found in internet that somebody shared in this website
(Waynehaffenden.com


RazorCSharpViewEngine.cs
view source

01 using System.Web.Mvc;
02 public class RazorCSharpViewEngine : RazorViewEngine
03 {
04 public RazorCSharpViewEngine()
05 {
06 AreaViewLocationFormats = new[]
07 {
08 "~/Areas/{2}/Views/{1}/{0}.cshtml",
09 "~/Areas/{2}/Views/Shared/{0}.cshtml"
10 };
11 AreaMasterLocationFormats = new[]
12 {

Your Global.ascs's Application start() method should be as following.

protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();

RegisterGlobalFilters(GlobalFilters.Filters);
RegisterRoutes(RouteTable.Routes);

ViewEngines.Engines.Add(new RazorCustomViewEngine());
}

OOD Project?

Today, one of my colleague ( as Senior developer), he told me his project is OOD programming project. I didn't say anything back to him. Just laughed myself.
Please look up following code whether it's OOD porject or not.

It's about binding Portfolio data from portfolio database.



I tired to add a new simple functionality to his code. And also he's always saying his code the best one.

Invalid operation. The connection is closed. ASP.NET MVC

In Entity framework 4.0.. datacontext shouldn't be static. so then, in every controller, you need to do a new instance of datacontext.

Otherwise, static datacontext can occur that two different request hitting will break the site.

Globalization .net


foreach (CultureInfo ci in CultureInfo.GetCultures(CultureTypes.
NeutralCultures))
{
DropDownListLang.Items.Add(new ListItem(ci.NativeName, ci.Name));
}


That's cool. You will get all available .net culture into the drop down list.

return confirm('" & strMessage & "');")

Most of people know the following codes.

btn.Attributes.Add("onclick", "return confirm('single " & strMessage & " single ');")

what I want to mention is "return confirm('" & strMessage & "')
sometime in development, you may need to do string manipulation. the similar case could be happened any time.

For reference purpose, I've hosted this post. If someone can reference on this, I am worth to put this post.

How to: Move a Database Using Detach and Attach (Transact-SQL)

You can move a detached database to another location and re-attach it to the same or a different server instance.

Attach the moved database and, optionally, its log by executing the following Transact-SQL statements:

USE master;
GO
CREATE DATABASE MyAdventureWorks
ON (FILENAME = 'C:\MySQLServer\AdventureWorks2008R2_Data.mdf'),
(FILENAME = 'C:\MySQLServer\AdventureWorks2008R2_Log.ldf')
FOR ATTACH;
GO

For a production database, place the database and transaction log on separate disks.

Enjoy on this !

MVC validation on controller.

The following link has very useful information for validation of mvc .

Before in my knowledge, I do understand the validation of mvc has to be placed on the model layer. That gives some headache to me to find right entity in entities.

That a pieces of codes saves my headache. That's just brilliant. Thanks to who posted this post. http://www.asp.net/mvc/tutorials/creating-model-classes-with-the-entity-framework-cs

// Validate
if (String.IsNullOrEmpty(movieToAdd.Title))
ModelState.AddModelError("Title", "Title is required!");
if (String.IsNullOrEmpty(movieToAdd.Director))

// Otherwise, reshow form
return View(movieToAdd);

How to postback on index change of ASP.net MVC dropdownlist?

How to postback on index change of ASP.net MVC dropdownlist?

I have found this on internet from this site

http://www.altafkhatri.com/Technical/ASP-NET-MVC-Dropdownlist/How-to-post-back/on-selectedIndexChanged

It is really helpful post. I put this on here future reference.

Steps to create the postback in ASP.Net MVC dropdownlist selectedindex change event:

Create a controller - Dropdownlist. Paste the code in the section below.
Create a view of the GetDD action binded to the strongly typed object(CoverObject). Paste the code in the section below.


Code in the controller

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.Mvc;

using System.Web.Mvc.Ajax;



namespace MvcApplication1.Controllers

{

public class CoverObject

{

public IList iliSLI;

public string SelectedName { get; set; }

public string Name { get; set; }

public string Address { get; set; }



public string formAction { get; set; }



public CoverObject()

{

iliSLI = new List();

SelectListItem sli = new SelectListItem();

sli.Text = "Altaf";

sli.Value = "1";



iliSLI.Add(sli);



sli = new SelectListItem();

sli.Text = "Krish";

sli.Value = "22";

Insert query return SCOPE_IDENTITY()

This is a example of how to get [table]ID back when you inserted a record to table.

this is very useful when you needed to do more business logic after table inserting.


ALTER PROCEDURE [dbo].[uspNewsletterSubscriptions_Insert]

@TitleId int,
@Forename nvarchar(255),
@Surname nvarchar(255),
@EmailAddress nvarchar(255),
@Id int OUTPUT

AS
BEGIN

insert into tNewsletterSubscriptions(TitleId, Forename, Surname, EmailAddress)
values(@TitleId, @Forename, @Surname, @EmailAddress)


SET @Id = SCOPE_IDENTITY()

SELECT [Id]
,[Created]
,[LastUpdated]
,[TitleId]
,[Forename]
,[Surname]
,[EmailAddress]

FROM tNewsletterSubscriptions
WHERE Id = SCOPE_IDENTITY()

END

Email Templates with C# asp.net

From my expected, GlobalRescource .resx file is obviously handy to store email templates.

You write whatever you want that Html email template or text email template in eg(contorlsculture.resx) under App_GlobalResources.

And follows following codes -

private string FormatEmailBody(StringBuilder emailBody)
{
emailBody.Replace("{jobtitle}", HttpUtility.HtmlEncode(drVacancy.Title));
emailBody.Replace("{reference}", HttpUtility.HtmlEncode(drVacancy.Reference));
emailBody.Replace("{location}", HttpUtility.HtmlEncode(drVacancy.Location));
emailBody.Replace("{salary}", HttpUtility.HtmlEncode(drVacancy.Salary));

emailBody.Replace("{title}", HttpUtility.HtmlEncode(txtTitle.Text));
emailBody.Replace("{firstname}", HttpUtility.HtmlEncode(txtFirstName.Text));
emailBody.Replace("{surname}", HttpUtility.HtmlEncode(txtSurname.Text));
emailBody.Replace("{email}", HttpUtility.HtmlEncode(txtEmail.Text));
emailBody.Replace("{telephone}", HttpUtility.HtmlEncode(txtTelephone.Text));
emailBody.Replace("{message}", HttpUtility.HtmlEncode(txtMessage.Text));

return emailBody.ToString();
}

private void SendEmail()
{
// Sends Job application to recruiter
string strEmailBody = FormatEmailBody(new StringBuilder(Resources.ControlsCulture.JobApplicationTemplate));
EmailHelper.SendMail(drVacancy.Title + " Job - Application", strEmailBody, new string[] { ConfigHelper.RecruitmentEmail }, null, null,
ConfigHelper.NoReplyEmail.ToString(), fuApplicationForm.PostedFile, fuCV.PostedFile, fuOpsForm.PostedFile);


txtTitle.Text = txtFirstName.Text = txtSurname.Text = txtEmail.Text = txtConfirmEmail.Text =
txtTelephone.Text = txtMessage.Text = "";
phMessage.Visible = true;
}

protected void lkbSubmit_Click(object sender, EventArgs e)
{
if (Page.IsValid)
{
SendEmail();
}
}

That takes you get sucessful email sending process.


But on the other hand, some opposite idea programmer wants to use a physical files for email templates.

Then creates template files under App_data folder.
now a little bit needs to update the code of sending email. Basically, uses IO and stringbuilder class.

Something like that :

private string FormatEmailBody(StringBuilder emailBody)
{
emailBody.Replace("{contact}", HttpUtility.HtmlEncode("Administrator"));
emailBody.Replace("{name}", HttpUtility.HtmlEncode(txtTitle.Text + " " + txtFirstName.Text + " "
+ txtSurname.Text));
emailBody.Replace("{email}", HttpUtility.HtmlEncode(txtEmail.Text));
emailBody.Replace("{housename}", HttpUtility.HtmlEncode(txtHouseName.Text));

emailBody.Replace("{street}", HttpUtility.HtmlEncode(txtNumberStreet.Text));
emailBody.Replace("{area}", HttpUtility.HtmlEncode(txtLocation.Text));
emailBody.Replace("{town}", HttpUtility.HtmlEncode(txtCity.Text));
emailBody.Replace("{county}", HttpUtility.HtmlEncode(txtCounty.Text));
emailBody.Replace("{postcode}", HttpUtility.HtmlEncode(txtPostcode.Text));
emailBody.Replace("{telephone}", HttpUtility.HtmlEncode(txtTelephone.Text));
emailBody.Replace("{enquiry}", HttpUtility.HtmlEncode(txtEnquiry.Text));

return emailBody.ToString();
}

private void SendEmail()
{
string sFullTemplatePath = HttpContext.Current.Server.MapPath(drFormEmails.EmailTxtFileName);
StringBuilder sbTemplate = new StringBuilder();
using (StreamReader sr = new StreamReader(sFullTemplatePath))
{
sbTemplate = new StringBuilder(sr.ReadToEnd());
}

string strEmailBody = FormatEmailBody(sbTemplate);
EmailHelper.SendMail("Contact us", strEmailBody, new string[] { drFormEmails.MailTo }, null, null,
drFormEmails.MailFrom);
}

protected void lbSubmit_Click(object sender, EventArgs e)
{
if (Page.IsValid)
{
SendEmail();
Response.Redirect("/Contact-us-confirmation");
}
}


Any better suggestion, please comment it. I will reply you.

how to display a value to textbox whos textmode is set to 'password' in c#

The code given below is to check the username n display the password via cookie. It works perfectly allright. since i want the value displayed in the password.text to be masked, i changed the textmode of the password.text to 'password'. as a result value isnt passed to the textbox.

Question: String cookiename = TextBox1.Text;

//grab cookie
HttpCookie cookie = Request.Cookies[cookiename];

//exists?
if (null == cookie)
{
Label1.Text = "cookie not found";
}
else
{
password.Text=cookie.Value.ToString();

}

Answer:

HttpCookie myCookie = new HttpCookie("MyTestCookie");
myCookie = Request.Cookies["MyTestCookie"];

TextBox2.Attributes.Add("value", cookie.Value.ToString());


The answer is just one line. but it saves a lot of time.
