I'm sorry to post this question because there's a lot of relative subjects with this one but unfortunately none of them couldn't helped me !! so I have an application that contains two wpf windows (MainWindow() and Window1()), what i exactly want to achieve is to control the window1 properties from the MainWindow().. for example i want to clear a listbox items from window1 every time i click on Button1 from the MainWindow !! I also want to have a full access to the methods, fields and properties that exits in the MainWindow from window1.

What you could do is to add public properties/method that allows access to your Window1 class from MainWindow.
For instance, if you want to clear a list in Window1 from MainWindow, add the following method to Window1:
public void ClearList()
{
// Clear your list here
}
Of course you'll need your MainWindow to know about Window1, but as the name suggests, I assume MainWindow is the main window so it creates the Window1 instance.
So you should have a reference to Window1 in MainWindow. In MainWindow, just call:
this.myWindow1.ClearList();

so like that i don't have to create a reference of Window1 in the MainWindow like windwo1 wind = new window1() ?

You do have to. How would you show the Window if you don't? First create your instance, then call a method of your instance.

thanks I'll do that when i need to, but the ClearList() method is not working with me.. when i implement the ClearList() in window1 and when i try to call it in the main window like Window1.ClearList(); it fails !!

@Destro009 Yes, because you are calling the method to the class itself, not to an instance of the class.

but it's okey when i use this !! like, this.window1.ClearList() i hope it works fine !!
Where is the problem ? I dont see any question.
Maybe you want to start by saving a ref of Window1 in MainWindow.
Window1 window1 = new Window1();
window1.show();
From there do what you need done :
window1.foo();
window1.bar();
window1.foobar = "Title";
Edit : some clarification, because OP seems to be a beginner :
public class MainWindow
{
private Window1 window1;
public void CreateWindow()
{
window1 = new Window1();
window1.show();
}
private void DoStuffWithWindow1()
{
window1.foo();
window1.bar();
window1.foobar = "Title";
}
}

yes i've already done that and get the StackOverFlowException !! An unhandled exception of type 'System.StackOverflowException' occurred in *****.exe

Hum, you must have some recursive call somewhere. Please post code. Are you using any events ?
NoobMaster69
no, the exception is about Window1 window1 = new Window1(); ps: i declare the window1 as global variable !!
squelos
Global ? As in class you mean ? When are you initializing window1 ? In the ctor of mainWindow ?
NoobMaster69
yes in the public partial class, but i don't understand why every time i run the app a new instance of window1 runs also !!
