Question

This is the code I made before I realized that the Calender control exists. And please never mind the typo [canlender]!

Somehow this code is making the state of whole IIS [Service Unavailable]. Doing net stop w3svc / net start w3svc won’t work too. The hosting provider said [What have you done?]. On my computer (IIS on Win8) would freeze too.

I don’t find anything that would make the server unable to service. It’s just creating and modifying controls… Any idea about the cause of this problem?

Thanks.

Answer 1

tc.Controls.Add(tc);

are you sure this is intended? it seems like a circular reference.
