hey ,
For each Language in .net You hould Create a Resource file
you go on each folder you want to localize ,
then righ click on the folder and create App_Localization folder
and then righ click on App_Loclization and add\new Item
then you should select Resource.resx file and give the complete Module ( page ) name you want to localize ,
it mean if you have a module with the name myTest.ascx then tou should create a myTest.ascx.resx file
and a myTest.ascx.en-US.resx file
notice that you sould place your region name in place of en-US , for example fa-IR
and then you should insert all localized item into resx file with meta:resourcekey="testLabel" and insert testLabel.Text into resx file and give a value for it
finally you should select a primary localization on your web.config in <globalization /> set the culture and uiculture in the tag ,
best regards
