Objects prorperties

Hello,

When I changed an aspx objects (forexample textbox's clickEvent name or 'id' name) property , it didn't change in source code automatically   (But it looks like changed in properties window... ) therefore when i run the web site, the object's property run with old value... 

 Is this a bug of visual studio?

i use visual studio 2008 sp1 (c#  - aspx)

Thanks a lot,

Okan Yaylagul
