can u tell me where the server control objects are created..
can i see the objects in the code as new Label();
i find only the references in the codebehind but not the instances of the controls.
The code behind is like an abstract class which contains the interface for server controls. It also contains the deftions of all methods which is the events handlers you code.
Now in in runtime you page or the aspx file in compiled by the ASP.NET to create a class inherted from the code behind with all the controls as the properties as loads to the memory .
All the controls will attach the event handlers to the methods in your code behind (managed function pointers).
Now as a derived class class can access all its base class methods and variables(upto protected level) these will get called when the event happens.
What type of application are you speaking of? WebForms or WinForms?
In Visual Studio with the code-behind (if you are using both) you can see where the controls are declared in a collapsed region that the IDE generates.
