How to Add Different Languages in Asp.net

Adding Different Languages in Asp.net

In this article , We will Learn about How languages are in websites in Asp.net

# Language Code for Different Languages

1. English ------- en-us (us)
2. French ------- fr-be (Belgium)
3. Germen ------- de-at (Austria)

# How to find other languages with its code

Goto Internet Explorer > Tools > Internet Option > Languages > Add

# We have to make txt file for languages

*Number of languages = number of txt file

Base name=abc   culture name=en    region name=us

abc.en-us.txt

abc.fr-be.txt

abc.de-at.txt

# After making txt files, convert them to resource file

abc.en-us.resources

abc.fr-be.resources

abc.de-at.resources

# Resources file = compressed  (common bitmap, icon, images, common string)

# Open Visual Studio and Make new Project

*Website >  Add new Item > Text file > abc.en-us.txt

a= Welcome

b= Hello

c= English

d= Hi

key =a          value = Welcome

Key is used to access and it should be in English.

*Website >  Add new Item > Text file > abc.fr-be.txt

a= Bienvenu

b= Bonjour

c= French

d= salut

*Website >  Add new Item > Text file > abc.de-at.txt

a= Herzlich willkommen

b= Hallo

c= Germen

d= Hallo

*Open Developer command prompt for VS 2017 and run as admin

Resgen – utility to convert txt to resource file

*Add new webform > then drop downlist

DropdownList> Tasklist> Edit Item> add > Text= English > Value = en-us

add > Text= French > Value = fr-be

add > Text= Germen> Value = de-at

*Enable autopostback

*Add 4 Label

#Code File

using System.Globalization; using System.Resources; using System.Threading;

Globalization – culture specific classes

Resources – to read/write information from resource file

Threading – multi-threading concept

#Global Application Class

-         one project one file
-         to manage application and session level events

#Website > Add new Item > Global Application Class

<%@ Application Language="C#" %> <%@ Import Namespace="System.Globalization"%> <%@ Import Namespace="System.Resources"%> <%@ Import Namespace="System.Threading" %>

void Application_Start(object sender, EventArgs e)

-         fire at first and one time only when project runs

void Application_Start(object sender, EventArgs e)     {         // Code that runs on application startup         Application["rm"] = ResourceManager.CreateFileBasedResourceManager("abc", Server.MapPath("."), null);     }

Rm= Global Variable (can be used in whole project)

. = current path

Null = current resource setting

# Make new method to fire the event everytime when request is send to server

void Application_BeginRequest(object sender, EventArgs e)     {         try         {             Thread.CurrentThread.CurrentCulture = new CultureInfo(Request.UserLanguages[0].ToString());         }         catch         {             Thread.CurrentThread.CurrentCulture = new CultureInfo("en-us");         }         Thread.CurrentThread.CurrentUICulture = Thread.CurrentThread.CurrentCulture;     }

Application_BeginRequest- Number of times is request send to server , the event should be fired same number of time

try, catch – Structure error handling (error handling)

on error goto – Unstructured error handling

try’s error will come in catch

Thread.CurrentThread- Current instance of the browser

CurrentCulture- to change the format not the culture

CultureInfo- it is a class of System.Globalization

CurrentUICulture- just to change the culture not the format

Format- it is date , time format and others etc

# Code File

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Globalization; using System.Resources; using System.Threading; public partial class _Default : System.Web.UI.Page {     ResourceManager rm;     protected void Page_Load(object sender, EventArgs e)     {         rm = (ResourceManager)(Application["rm"]);         if (Page.IsPostBack==false)         {             Label1.Text = rm.GetString("a").ToString();             Label2.Text = rm.GetString("b").ToString();             Label3.Text = rm.GetString("c").ToString();             Label4.Text = rm.GetString("d").ToString();         }     }     private void Set_Cul(String d)     {         Thread.CurrentThread.CurrentUICulture = new CultureInfo(d);         Label1.Text = rm.GetString("a").ToString();         Label2.Text = rm.GetString("b").ToString();         Label3.Text = rm.GetString("c").ToString();         Label4.Text = rm.GetString("d").ToString();     } }

String d- to pass culture code

# Design

*Double click DropDownList

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)     {         Set_Cul(DropDownList1.SelectedValue);     }

How to Work with FormView Control in Asp.net

FormView Control In Asp.net

This Article explain the FormView Control and its use in Asp.net program

# FormView

-         It is similar to DetailView

-         In it we can display single record

-         No rows or Column (Customised view and all Feature details)

-         Paging is inbuilt

# Templates applied

-         Item Template

-         Header Template

-         Footer Template

-         Edit Item Template

-         Pager Template

-         Insert Item Template

-         Empty Data Template

# Open Visual Studio and Make new Project

*Add new webform

*Toolbox > Data > FormView

#Coding

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Data; using System.Configuration; using Microsoft.ApplicationBlocks.Data; public partial class Default2 : System.Web.UI.Page {     String psg;     protected void Page_Load(object sender, EventArgs e)     {         psg = ConfigurationManager.ConnectionStrings["ps"].ConnectionString;         if (Page.IsPostBack == false)         {             Form_Bind();         }     }     private void Form_Bind()     {         DataSet ds = SqlHelper.ExecuteDataset(psg, "dispemp");         FormView1.DataSource = ds;         FormView1.DataBind();     } }

# Design

*FormView> Tasklist> Edit Template

# Item template

Empno : Label > Edit Data Binding > Eval(“empno”)

Name : Label > Edit Data Binding > Eval(“ename”)

Address : Label > Edit Data Binding > Eval(“eadd”)

Salary : Label > Edit Data Binding > Eval(“esal”)

Add Link Button > Property > Text = Edit > Command Name= edit

Add Link Button > Property > Text = Delete> Command Name= delete

Add Link Button > Property > Text = New> Command Name= new

# Edit Item template

Empno : Label > Edit Data Binding > Eval(“empno”)

Name : TextBox > Edit Data Binding > Eval(“ename”)

Address : TextBox > Edit Data Binding > Eval(“eadd”)

Salary : TextBox > Edit Data Binding > Eval(“esal”)

Add Link Button > Property > Text = Update > Command Name= update

Add Link Button > Property > Text = Cancel> Command Name= cancel

# Insert Item template

Empno : TextBox

Name : TextBox

Address : TextBox

Salary : TextBox

Add Link Button > Property > Text = Insert > Command Name= insert

Add Link Button > Property > Text = Cancel> Command Name= cancel

# Empty Data Template

Add Button > Text = Add More Data > Command Name= new

#FormView > Properties> Allow paging= True

# FormView > Properties> Events > Page Index Changing

protected void FormView1_PageIndexChanging(object sender, FormViewPageEventArgs e)     {         FormView1.PageIndex = e.NewPageIndex;         Form_Bind();     }

 # Drawbacks of Inbuilt Paging

-         It will bind all the records in the table for example 200,000 but show one record

-         Low performance

# Mode Concept in FormView

In FormView there are 3 modes=

1.     Edit Mode= It will call Edit Item Template

2.     Insert Mode = It will call Insert Item Template

3.     Read Only Mode = It will call Item Template

# FormView > Properties> Events > Mode Changing

protected void FormView1_ModeChanging(object sender, FormViewModeEventArgs e)     {         FormView1.ChangeMode(e.NewMode);         Form_Bind();     }

# Save Code

* FormView > Properties> Events > Item Inserting

protected void FormView1_ItemInserting(object sender, FormViewInsertEventArgs e)     {         Int32 eno, es;         String en, ed;         eno = Convert.ToInt32(((TextBox)(FormView1.FindControl("TextBox4"))).Text);         en = ((TextBox)(FormView1.FindControl("TextBox5"))).Text;         ed = ((TextBox)(FormView1.FindControl("TextBox6"))).Text;         es = Convert.ToInt32(((TextBox)(FormView1.FindControl("TextBox7"))).Text);         Object[] ar = new Object[4];         ar[0] = eno;         ar[1] = en;         ar[2] = ed;         ar[3] = es;         SqlHelper.ExecuteNonQuery(psg, "insemp", ar);         FormView1.ChangeMode(FormViewMode.ReadOnly);         Form_Bind();     }

# For Update

* FormView > Properties> Events > Item Updating

protected void FormView1_ItemUpdating(object sender, FormViewUpdateEventArgs e)     {         Int32 eno, es;         String en, ed;         eno = Convert.ToInt32(((Label)(FormView1.FindControl("Label5"))).Text);         en = ((TextBox)(FormView1.FindControl("TextBox1"))).Text;         ed = ((TextBox)(FormView1.FindControl("TextBox2"))).Text;         es = Convert.ToInt32(((TextBox)(FormView1.FindControl("TextBox3"))).Text);         Object[] ar = new Object[4];         ar[0] = eno;         ar[1] = en;         ar[2] = ed;         ar[3] = es;         SqlHelper.ExecuteNonQuery(psg, "updemp", ar);         FormView1.ChangeMode(FormViewMode.ReadOnly);         Form_Bind();     }

# For Delete

* FormView > Properties> Events > Item Deleting

protected void FormView1_ItemDeleting(object sender, FormViewDeleteEventArgs e)     {         Int32 eno;         eno = Convert.ToInt32(((Label)(FormView1.FindControl("Label1"))).Text);         Object[] ar = new Object[1];         ar[0] = eno;         SqlHelper.ExecuteNonQuery(psg, "delemp", ar);         Form_Bind();     }
