Aug 20, 2010 at 9:04 PM

I have a three dropdown listboxes (Ext) each of them bound to the database and it get populated once the previous dropdownlistselection change , when the second once selection change it postback and fire both events (the first dropdownlist and then the second dropdownlist)  this issue only occure when i deploy the page to IIS 7 (asp.net Classic) and it works fine in the asp.net development web server . i have also tested it on multiple pc's (all runing IIS 7 ,64 OS,win 7 / win 2008) and they preform the same , i tested also your sample code (china ShengShiXian page) and once i bind the controls to the database (dataset)  it had the same issue.
