Report localization in Telerik self hosted service (.trdx) - asp.net

Question

I have telerik REST web API(ASP.NET ) which is working fine. Now I need to localize the reports (report are in .trdx extension).
From documentation of telerik I found the code which have place in my BaseTelerikReportsController but this also not working, and even not show any error.
Telerik Localization Documentation
public class BaseTelerikReportsController : ReportsControllerBase
{
static readonly Telerik.Reporting.Services.ReportServiceConfiguration ConfigurationInstance;
static BaseTelerikReportsController()
{
var resolver = new CustomReportResolver();
//Create new CultureInfo
var cultureInfo = new System.Globalization.CultureInfo("aa-iq"); //<-- Line 1
// Set the language for static text (i.e. column headings, titles)
System.Threading.Thread.CurrentThread.CurrentUICulture = cultureInfo; //<-- Line 2
var reportsPath = HttpContext.Current.Server.MapPath("~/Reports");
ConfigurationInstance = new Telerik.Reporting.Services.ReportServiceConfiguration
{
HostAppId = "TBReportApp",
ReportResolver = resolver,
// ReportResolver = new ReportFileResolver(reportsPath),
Storage = new Telerik.Reporting.Cache.File.FileStorage(),
};
}
public BaseTelerikReportsController()
{
ReportServiceConfiguration = ConfigurationInstance;
}
}
Note
There is a similar question but don't guide me to any right direction Here
Update 1
I have added below function in Global.asax.cs.
protected void Application_AcquireRequestState(object sender, EventArgs e)
{
//Create new CultureInfo
var cultureInfo = new System.Globalization.CultureInfo("ar");
// Set the language for static text (i.e. column headings, titles)
System.Threading.Thread.CurrentThread.CurrentUICulture = cultureInfo;
// Set the language for dynamic text (i.e. date, time, money)
System.Threading.Thread.CurrentThread.CurrentCulture = cultureInfo;
}
After above line (see image) data under red mark is localize but i need to localize yellow one(i.e heading)

I figure out how to localize the report header. Following are the some summarized steps.
Add App_GlobalResources folder and .resx accordingly your languages (See the figure 1-1).
Send language attribute from 'HTML5 Viewer'.
var viewer = $("#report-viewer").data("telerik_ReportViewer");
var model = {
//other attributes
Language: this.selectedLanguage //Here value may be ,en Or ar
};
viewer.reportSource({
report: reportSettings,
parameters: model
});
On server side based on that attribute change label accordingly.
private static void Localization(ref Report reportInstance)
{
ResourceManager currentResource = null;
switch (_language)
{
case "en":
currentResource = new ResourceManager("Resources.en", System.Reflection.Assembly.Load("App_GlobalResources"));
break;
case "ar":
currentResource = new ResourceManager("Resources.ar", System.Reflection.Assembly.Load("App_GlobalResources"));
break;
}
// var MyResourceClass = new ResourceManager("Resources.ar", System.Reflection.Assembly.Load("App_GlobalResources"));
ResourceSet resourceSet = currentResource.GetResourceSet(CultureInfo.CurrentUICulture, true, true);
foreach (DictionaryEntry entry in resourceSet)
{
string key = entry.Key.ToString();
string value = entry.Value.ToString();
var items = reportInstance.Items.Find(key,true);
foreach (var singleItem in items)
{
var singleItemType = singleItem.GetType();
//if (singleItem.GetType().FullName == "") ;
if (singleItemType.FullName == "Telerik.Reporting.TextBox")
{
var castItem = (Telerik.Reporting.TextBox) singleItem;
castItem.Value = value;
}
}
}
}
On Telerik Standalone Report Designer
Change your report(.trdx) Textbox value which matches your .resxname value pair.
