Yeni sunucumuzu aldik ve Windows 2008 'i hemen kurdum. Tabii icinde IIS 7.0'da geldi. Blogumu iis6'dan iis 7'ye tasimak sandigimdan fazla zamanımı aldı.
Eğer sizde bu problemle karşılaşırsanız düzeltmeniz gereken tek dosya web.config 'dir.

</system.web> satirindan sonra asagida verdigim kodu eklemelisiniz.

<system.webServer>

<!--The CleanPageModule below removes whitespace which makes the page load faster in IE. Enable at own risk -->

%systemroot%\system32\inetsrv\APPCMD.EXE migrate config "BlogSiteName/"

Guzel bir calisma sizinle paylasmak istedim.

DropDownList kontrolune veritabanından kayitlari yukledigimiz zaman ilk secilmis Item'in gelen kayitlar disinda bilgilendirici bir secenek olmasini isteriz.
Ornegin ; "Bir Sehir Secin." , "Bir Bölüm Seçin" gibi. Bunu CodeBehind tarafinda cok kolay DropDownList'imize ekleyebiliriz.

protected void Page_Load(object sender, EventArgs e)
 {
  DropDownList1.Items.Insert(0, new ListItem("Seçiniz...", "0"));
}
