How to set Binding for PasswordBox?

Question

WPF

In the authorization window for the PasswordBox, you need to bing . I found the right example , but it is difficult for me to understand, and even in English. I would like to get sensible explanations on how to perform this binding or get a simple example.

Answer 1

Binding for PasswordBox is not implemented quite intentionally, so that it would not be so easy to intercept the password entered in the field.
As a standard and relatively safe practice, I often use passing a PasswordBox as a parameter to the login command.

<TextBox Text="{Binding Login}" x:Name="TbxLogin" />
<PasswordBox x:Name="PasswordBox" />
<Button Content="Log in" Command="{Binding SigninCommand}"
    CommandParameter="{Binding ElementName=PasswordBox}" IsDefault="True" />

public ICommand SigninCommand { get; set; }
private void Signin(object param)
{
  var passwordBox = param as PasswordBox;
  if (passwordBox == null)
    return;
  var password = passwordBox.Password;
        ...
}
