hi everybody,
I solved the problem in a mechanic way.
In default page there wasn t turkish characters problem. So I changed its name on my desktop. added my project using "add existing item" -. I m using Visul Studio-. Changed its contain with my other pages' for example Items page. And it worked. I did the same for other pages.
But I still deserve to learn its reason. Why he created this problem. If is there anybody interest with the subject. I will try to tell the subject in detail.
-I set up small business starter kit (as www.cajareklam.com) connected the sql server database and it worked. then I try to change in it' s pages with turkish words.
-there wasnt problem with default page. But in other pages there were problem partly. I solved that page parts that don t create problem were feeding from sql or xml databases.
then I tried to solve the problem in some parts of page that don t show turkish character correct.
-default encoding was utf-8 . And I know that it works pretty good with turkish characters. But to be sure ı cahnged with turkish(ISO). And it didn t work. I made numerous changes of encoding, culture,ui in pages and web.config. And they didn t work.
-I even tried to make copy of default page with its code page(only page that works correct). First I added a web form to the project linked it to menu controls. And then I copied and pasted all the text in default,aspx and default.aspx.cs to the new page. This didn t work also.
so gentlemen if you have an answer about the problem pls write an answer.
yhanks a lot
