Gets or sets a value that indicates whether the ScriptManager control renders localized versions of script files.
Assembly: System.Web.Extensions (in System.Web.Extensions.dll)
When the property is set to true, the ScriptManager object will retrieve script files for the current culture if they exist. For example, a page might specify a script file that is named CustomScript.js. If the culture is set to fr-CA, the ScriptManager object will try to retrieve a script file that is named CustomScript.fr-CA.js.
To prevent a script file from being rendered two times, the property must not be modified during an asynchronous postback.
