CAUSE
When you batch compile a page, the namespace
_ASP is used for the
resulting assembly. When you do not batch compile a page, the namespace
ASP is used for the resulting assembly. If a user requests a page that is contained
in the namespace
_ASP, and then the page is modified and the user is posted back,
the namespace might change to
ASP when the page is recompiled.
Because the namespace is different, the Control tree for
the second request does not match the original Control tree. This problem causes ASP.NET not to
interpret the request as a postback. ASP.NET determines that a request is a
postback request based on the following conditions:
- Request.Forms or Request.QueryString collection is not
empty
- Page Control tree has not changed
- Not the initial request
Note This problem occurs most frequently in Web farm
scenarios.
