Using it couldn’t be simpler, just add a reference to the namespace in your XAML, and update your PasswordBox with the BoundPasswordBox class. SetBoundPassword(password, password.Password) PasswordBox password = sender as PasswordBox Static void PasswordChanged(object sender, RoutedEventArgs e) Password.PasswordChanged += new RoutedEventHandler(PasswordChanged) Password.Password = e.NewValue.ToString() Password.PasswordChanged -= PasswordChanged Disconnect the handler while we're updating. Private static void OnBoundPasswordChanged( / Handles changes to the BoundPassword property. ![]() Public static void SetBoundPassword(DependencyObject d, string value)ĭ.SetValue(BoundPasswordProperty, value) Return (string)d.GetValue(BoundPasswordProperty) Public static string GetBoundPassword(DependencyObject d) PasswordBox and binding When you need to obtain the password from the PasswordBox, you can use the Password property from Code-behind. New FrameworkPropertyMetadata(string.Empty, OnBoundPasswordChanged)) Public static readonly DependencyProperty BoundPasswordProperty =ĭependencyProperty.RegisterAttached("BoundPassword", / BoundPassword Attached Dependency Property / This class adds binding capabilities to the standard WPF PasswordBox. Good news, folks – the following class (taken from my forthcoming Twitter client Songbird) is a way to perform binding with the PasswordBox. If, however, you aren’t too worried about this potential security breach, there is a workround. ![]() There’s a good reason for this lack of binding – PasswordBox.Password is not a Dependency Property, ostensibly because this would result in the password being stored in clear text in memory, which is a potential security concern. Yes, you heard it right, you can’t bind with a PasswordBox. Superficially, this control looks like a textbox, but there is a problem when you write MVVM applications and rely on binding the way I do you can’t bind to it. There is one stain in the awe inspiring goodness that is bound applications, and that’s the PasswordBox. Thanks.Those who’ve been following my blog and conversations with the WPF Disciples know that I love the databinding power of WPF, and in almost all cases I’m a very happy bunny.

I have done same thing with TextBox, but it doesnt work with PasswordBox. I have used this for password property Īnd bound to that property with PasswordBoxAssistant Īnd have made custom PasswordBoxStyle that is BasedOn ControlBaseStyle I wan't to achieve same thing with passwordBox to give feedback to user about errors (Constraints) when entering password ![]() It's showing error message for Username property I don't know how to extract error message to show it in tooltip i that AdornedElementPlaceholder Is there a way to show error message in AdornedElementPlaceholder while verifiying PasswordBox.Īnd im my BaseControlStyle im using that validation Īnd it's working like a charm with almost every control that i have(Combobox,DateTimePicker,TextBox) but when i want to use same style for passwordBox it doesn't work.Īt picture you can see that it's working with simpe TextBox but not with PasswordBox.
