Intellisense not showing anything I write

I am using Visual C# 2008 express. I'm also running Windows 7. I created a simple form, but Intellisense doesn't show anything I wrote. I write:

private RadioButton rbtn_sortLocation;

And then when I write rbtn,Intellisense pops up, but it doesn't show rbtn_sortLocation. But after writing out a whole line, it doesn't complain about an error. How do I get Intellisense to show my methods and such?

Also: 开发者_Python百科This is only happening to solutions I create on this computer. All of the solutions I created on my old XP machine work fine.

You can give Ctrl + Space a shot. Its a way to pull up the Intellisense menu manually.

You can also check your options to make sure its turned on. I believe the intellisense option is under Tools -> Options -> Text Editor -> (All Languages or the language you are using) -> Statement Completion section -> Auto list members

Where are you writing 'rbtn' and trying to open intellisense? Also, where is this RadioButton declared?

Intellisense populates the menu with options based on the scope. For example: (assuming the RadioButton is declared at class-level)

class MyClass 
{
    private RadioButton rbtn_sortLocation;

    // Intellisense will not show the RadioButton in this scope.
    // This is the class scope, not in a method.

    static void StaticMethod() 
    {
        // Intellisense will not show the RadioButton in this scope.
        // The RadioButton is not static, so it requires an instance.
    }

    class InnerClass
    {
        // Intellisense will not show the RadioButton in this scope.
        // This is the class scope, not in a method.

        void InnerClassMethod()
        {
            // Intellisense will not show the RadioButton in this scope.
            // Members of the outer class are not accessible to an inner class.
        }
    }

    public MyClass()
    {
        // Intellisense WILL show the radio Button in this scope.
        // class members are accessible to the constructor.
    }

    void Method()
    {
        // Intellisense WILL show the radio Button in this scope.
        // class members are accessible to instance methods.
    }
}
