XAML & C# Getting started

Question

I'm developing a XAML with C# and I haven't programmed much with C#. I am finding that the XAML scripting is coming along okay but I am a little lost with the C#. I have designed an interface From with Tabs Buttons Text fields Combo boxes etc and now I am trying to write the C# event code behind the buttons but I can't even write a command to get the From to close. I have a few years experiences with C++ VBA VB.net and Java etc so I understand the command statements -  MessageBox .Show(HelloWorld); . However the code  private void cmdClose_Click( object sender RoutedEventArgs e) {Page1().close;}  will not work for me and close my XAML form call Page1. Why???

this keyword represents the current instance of the class where you call it. By calling this.Parent you are actually calling the parent of the current class.

Thank You. I'm a little confused though. Why this.parent I've seen/used the this command before in VB.net & C++ and understand it's referring to the current object and I can understand that your code is instructing the Parent of the current object to close but why do you need to instruct the parent of the current object to close? Can you use the name of the object to want to close? Like –  (frmAdmin as Window ).Close();  or  (Page1 as Page).Close();

private void button1_Click( object sender RoutedEventArgs e) { ( this .Parent as Window ).Close(); }
