firstly, make acquainted concept of globalization here , understand use of global , local resource files handle kind of requirements have. 1 simple definition given here too.

so, in short, should better generate local resources each language , override initializeculture() method set page's uiculture property choose appropriate language specific file , when dropdownlist selection changes.

step 1: generate language specific resource files (.resx )

1. select option: tools -> generate local resource in visual studio. if suppose aspx file named: default.aspx, visual studio creates new folder named app_localresources, , within app_localresources folder, new file named default.aspx.resx. in default.aspx.resx, should put neutral languge( english) text.

2. next, create resource file specific french language

   in solution explorer, right-click default.aspx.resx file, and
   click copy.

   right-click app_localresourcesfolder, , click paste.

   visual studio creates file named copy of default.aspx.resx.

   rename default.aspx.fr.resx. resource file represents page content in french language.

   open default.aspx.fr.resx , add french text.

3. same way create language specific resource file urdu. [ file name be: default.aspx.ur.resx ]

step 2:
keep in mind asp.net pick appropriate language specific resource file based on pages' uiculture value. set uiculture property of page, must override intializeculture() method , set property there:

// use request.form["dropdownlist1"] access dropdownlist value

protected override void initializeculture() {     if (request.form["dropdownlist1"] != null)     {         string selectedlanguage = request.form["dropdownlist1"];         uiculture = selectedlanguage ;         culture = selectedlanguage ;         thread.currentthread.currentculture =              cultureinfo.createspecificculture(selectedlanguage);         thread.currentthread.currentuiculture = new              cultureinfo(selectedlanguage);     }     base.initializeculture(); }
