New Post: VS 2010 MVC 2 and Custom method.

I'm trying to understand the execution sequence of Custom method. I've MCV2 and VS 2010. I've different  rules defined in the c'tor and Custom method.

I'm not sure at which stage  the Custom method is executed? I put the break point on Custom method in the c'tor and on the Custom method as well. The cursor goes in the c'tor several times during the execution cycle but only once in the Custom method. At which stage the Custom method is executed?
