سلام
من از AsyncFileUpload که از کنترل های AjaxControlToolkit استفاده میکنم
در صفحه دو تا DropDownList دارم که درون Update Panel قرار دارند و به هم متصل هستند

اما وقتی DropDownList1 را انتخاب میکنیم متد drop1_SelectedIndexChanged عمل نمیکنه

حالا اگه بیایم و فانکشن زیر را به حالت کامنت دربیاریم همه مشکل حل میشه
کسی میدونه دلیل این تداخل چیه

فانکشن مورد نظر
function StartUpload(sender, args) {
document.getElementById('lblStatus').innerText = 'Uploading Started.';
}




کد های کامل برنامه را هم میزارم
