I want to access my controls like button or textbox in mainWindow in WPF, but I can't do this.
In Windows Form application it's so easy, you can set modifier of that control to True and you can reach that control from an instance of that mainWindow, but in WPF I can't declare a public control. How can I do this?

NavigationService is for browser navigation within WPF. What you are trying to do is change to a different window TrainingFrm .

To package content for navigation, WPF provides the Page class. You can navigate from one Page to another declaratively, by using a Hyperlink, or programmatically, by using the NavigationService. WPF uses the journal to remember pages that have been navigated from and to navigate back to them.
To access controls in another WPF forms, you have to declare that control as public. The default declaration for controls in WPF is public, but you can specify it with this code:
<TextBox x:Name="textBox1" x:FieldModifier="public" /> And after that you can search in all active windows in the application to find windows that have control like this:
foreach (Window window in Application.Current.Windows) { if (window.GetType() == typeof(Window1)) { (window as Window1).textBox1.Text = "I changed it from another window"; } } If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
