WPF PasswordBox does not support binding workarounds

The password property of PasswordBox does not support direct binding for security reasons, and can be implemented using dependency properties. Inserting code directly

public class Passwordboxhelper {public static readonly DependencyProperty Passwordproperty = Depende Ncyproperty.registerattached ("Password", typeof (String), typeof (Passwordboxhelper), new Frameworkpro Pertymetadata (String.        Empty, onpasswordpropertychanged));            public static readonly DependencyProperty Attachproperty = dependencyproperty.registerattached ("Attach",        typeof (BOOL), typeof (Passwordboxhelper), new PropertyMetadata (False, Attach)); private static readonly DependencyProperty Isupdatingproperty = dependencyproperty.registerattached ("isupdating"        , typeof (BOOL), typeof (Passwordboxhelper)); public static void Setattach (DependencyObject DP, BOOL value) {DP.        SetValue (attachproperty, value); public static bool Getattach (DependencyObject DP) {return (BOOL) DP.        GetValue (Attachproperty); } public static string GetPassword (DEpendencyobject dp) {return (string) DP.        GetValue (Passwordproperty); public static void SetPassword (DependencyObject dp, String value) {DP.        SetValue (passwordproperty, value); } private static bool Getisupdating (DependencyObject DP) {return (BOOL) DP.        GetValue (Isupdatingproperty); } private static void Setisupdating (DependencyObject DP, BOOL value) {DP.        SetValue (isupdatingproperty, value); } private static void Onpasswordpropertychanged (DependencyObject sender, Dependencypropertychangedeventa            RGS e) {PasswordBox PasswordBox = sender as PasswordBox;            Passwordbox.passwordchanged-= passwordchanged; if (! (            BOOL) getisupdating (PasswordBox)) {Passwordbox.password = (string) e.newvalue;        } passwordbox.passwordchanged + = passwordchanged; } private static void ATtach (DependencyObject sender, DependencyPropertyChangedEventArgs e) {PasswordBox Passwordb            Ox = sender as PasswordBox;            if (PasswordBox = = null) return;            if (bool) e.oldvalue) {passwordbox.passwordchanged-= passwordchanged;            } if ((bool) e.newvalue) {passwordbox.passwordchanged + = passwordchanged; }} private static void PasswordChanged (object sender, RoutedEventArgs e) {PasswordBox P            Asswordbox = sender as PasswordBox;            Setisupdating (PasswordBox, true);            SetPassword (PasswordBox, Passwordbox.password);        Setisupdating (PasswordBox, false); }    }

Use:

  <passwordbox helper:passwordhelper.attach= "True" helper:passwordhelper.password= "{Binding Model.Password, Mode= TwoWay, updatesourcetrigger=propertychanged} ">       <PasswordBox.InputBindings>           <keybinding key=" Enter "command=" {Binding logincommand} "/>       </PasswordBox.InputBindings>   </PasswordBox>
