Data Controls :: DataList Pagination Direction

According to thread [URL] .... 

I used pagination for datalist and pagination look like below:

Last Previous ... 4 3 2 1 Next First

 it is work correctly  I want right to left pagination but problem is that here in below code:

  private void PopulatePager(int recordCount, int currentPage) {
double dblPageCount = (double)((decimal)recordCount / (decimal)PageSize);
int pageCount = (int)Math.Ceiling(dblPageCount);
List<PagerPage> pages = new List<PagerPage>();
if (pageCount > 0) {
pages.Add(new PagerPage("Last", pageCount.ToString(), currentPage < pageCount, "button"));

[Code] .....

when I changed "first" "Next" "previous" "Last" to persian character:"First='اولین'"   "Next='بعدی'"   "previous='قبلی'"   "Last='آخرین'"

again page number direction changed to left to right:

  1 2 3 4 ...

private void PopulatePager(int recordCount, int currentPage) {
double dblPageCount = (double)((decimal)recordCount / (decimal)PageSize);
int pageCount = (int)Math.Ceiling(dblPageCount);
List<PagerPage> pages = new List<PagerPage>();
if (pageCount > 0) {
pages.Add(new PagerPage("آخرین", pageCount.ToString(), currentPage < pageCount, "button"));

[Code] ....

why this happen? Above code worked correctly just when text be in english character when I change to persian or this character "<< < >> >"  it changed number direction. what should I do?
