Hi All,

We have created web parts as user controls and attributed some their properties as [Personalizable]. Add added few web parts to the different zones in page.

Every thing works fine. But whenever a Website is upgraded , all the web parts added will disappear.

What could be the issue. Since web parts controls are of different version after upgraded.. Is this is the reason?

Any ideas?

Thanks in advance

Do you mean the Personalization data was set back to default and the previous personalization was cleared? Maybe this short discussion may help you: http://forums.asp.net/t/1320411.aspx
