Private code-behind methods ignored by the compiler - ASP.NET

Question

When declaring a code method as private (for example, an event handler), the compiler ignores it and produces:

"Compiler error message: CS1061:" ASP.default_aspx "does not contain a definition for" OnLoginUser ", and the extension method" OnLoginUser "cannot be found that accepts the first argument of type" ASP.default_aspx "(you do not see using the directive or link to assembly?) "

In practice, OnLoginUsed exists, and when the identifier is changed to "public \ protected", everything works fine.

The question is, why is it impossible to declare such a method private? after all, it is called internally by other members of the class.

Your ASPX page does not match your code per page. He inherits it, and therefore he cannot see private members. That is why they must be protected or open.
