I can't figure out how to invoke a method that I described in a WPF page that is located in a frame inside my mainwindow through my second WPF window.

I tried:(In the window that is invoking the method)

C#

var page= new Page1() as Page1; 
page.addgoal(txtbox_Name.Text);

(addgoal is my method)
I tried to invoke the method addgoal() though the method does not produce the desired result on Page1, which has to be open
Thanks to all!

You don't "invoke" methods, you just call them. (But you invoke, say, delegate and event instances, delegate instances via the Dispatcher or directly.)
Calling a method is the most basic, fundamental and trivial thing. Therefore, it's hard to understand how it possibly could cause any confusions. Perhaps you can get help if you explain more.

Alright, I want to call the method. Thank you for correcting my error for I am new to programming. In the window, I cannot simply write Page1.addgoal(string Name). And I also do not want to create a new instance of page 1 to open, so how can I call the method in my page?

Why cannot you? Actually, I don't know what is Page1. First of all, you need to understand static vs instance methods. Instance method is called on an instance (which is, technically, passed just the first implicit argument "this"), and static method is just the class/struct method. Understanding all that, you just apply some logic. But it you face the problem of how to design the code, I'll try to help.
