[CLOSED] Adding multiple Fields
Hi,
I have the problem, when I add multiple Fields/Labels in code behind I alway get the same error.
Server Error in '/' Application.
A Control with an ID of "False" has already been initialized. Please ensure that all Controls have a unique id.
The following Control has the same ID as at least one other Control on the Page. All Controls must have a unique ID.
What I'm doing wrong?
