User-47461065 posted

I have a page that has dropdownlist and with save button which saves language. Now I need to store a language in browser that was saved lastly. For example if the language is Hindi, then next time if I open the site, it should open in Hindi language.

how to store selected language in browser?

Please help me!! I am new to this.

My code for base page and master page are as follows:

class page which the child pages inherits:
Public Const LanguageDropDownName As String = "ctl00$Contentplaceholder1$ddlLanguage"     Public Const PostBackEventTarget As String = "__EVENTTARGET"
Protected Overrides Sub InitializeCulture()
     
   If (Request(PostBackEventTarget)) IsNot Nothing Then
            Dim controlID As String = Request(PostBackEventTarget)

            If controlID.Equals(LanguageDropDownName) Then

                Dim selectedValue As String = Request.Form(Request(PostBackEventTarget)).ToString()

                Select Case selectedValue
                    Case "0"
                        SetCulture("en-US", "en-US")
                        Exit Select
                    Case "1"
                        SetCulture("te-IN", "te-IN")
                        Exit Select
                    Case Else
                        Exit Select
                End Select

            End If

        End If

        If Session("MyUICulture") IsNot Nothing AndAlso Session("MyCulture") IsNot Nothing Then
            Thread.CurrentThread.CurrentUICulture = DirectCast(Session("MyUICulture"), CultureInfo)
            Thread.CurrentThread.CurrentCulture = DirectCast(Session("MyCulture"), CultureInfo)
        End If
MyBase.InitializeCulture()
    End Sub

Protected Sub SetCulture(ByVal name As String, ByVal locale As String)
        Thread.CurrentThread.CurrentUICulture = New CultureInfo(name)
        Thread.CurrentThread.CurrentCulture = New CultureInfo(locale)
        Session("MyUICulture") = Thread.CurrentThread.CurrentUICulture
        Session("MyCulture") = Thread.CurrentThread.CurrentCulture
    End Sub

This is the master page code which I am using now:

if Not IsPostBack() Then
        If Session("Language") IsNot Nothing Then
            ddlLanguage.SelectedIndex = ddlLanguage.Items.IndexOf(ddlLanguage.Items.FindByValue(Convert.ToString(Session("Language"))))
            End If
       End If
End Sub


Protected Sub ddlLanguage_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddlLanguage.SelectedIndexChanged
        Session("Language") = ddlLanguage.SelectedValue
End Sub

But i have to keep the dropdownlist in separate page .

how can i store the language?

Use statemanagement techniques. Like cookies, Sessions, viewstate.

here is one example to create cookie

When you visit same page next time to get saved language, you have to check cookie is exist or not. here is help

Thanks for helping me.

Here is the solution I got:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
Dim cultureCookie As HttpCookie = Request.Cookies("Culture")
Dim cultureCode As String = If((cultureCookie IsNot Nothing), cultureCookie.Value, Nothing)
If Not (String.IsNullOrEmpty(cultureCookie)) Then
ddlLanguage.SelectedValue =  cultureCode
End If
End If
End Sub


Protected Sub ddlLanguage_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddlLanguage.SelectedIndexChanged
Request.Cookies.Add(New HttpCookie("Culture", ddlLanguage.SelectedValue))
Response.Redirect(Request.Url.AbsolutePath)
End Sub
