Same Error

[help]

I am having the same thing happen. I start a new AJAX enabled website
in VS2005 SP1. Proceed to add a simple business object from the
walkthrough and then add a report. The object data sources show up for
a while and then suddenly disappear after adding more objects to the
project and rebuilding. Any update on a fix would be appreciated.
Thanks.

are you adding your controls dynamically or programmatically?

are your controls in update panels?

is viewstate enabled for the controls?

I would imagine that the most likely cause of the problem is that your
controls are not being rendered because their state is not being saved.

please post some more details of your app
