I have the MainPage class which I can edit the contents of the XAML textbox from using this code
box1.Text = "";
however trying to edit the textbox from another class the following code will do not work
MainPage.box1.Text = "";
The error is "An object reference is required for the non-static field, method or property 'class.MainPage.box1' I have tried everything like making static functions and creating new MainPage objects in the other class but nothing has worked.
You are trying to access a static field of the MainPage class without an object instance.
You'll need an instance of the MainPage class to access it like this:
MainPage myPage = new MainPage();
myPage.box1.Text = "";
