Thanks very much for this excellent post (realizing that it's 3.5 years old... the Internets that keep on giving), this was exactly what I needed.

Hi,

Thank you for this usefull piece of code.

BoundPassword, BindPassword and UpdatingPassword should be respectilvly named BoundPasswordProperty, BindPasswordProperty and UpdatingPasswordProperty to avoid the "dependency property missing" problem in xaml.

That was an excellent solution!

2011-11-03T15:15:35.358Z

That was an excellent solution!

My comment that "I've corrected it" was aimed at Ross, not Jared :-)

So, I've not made any changes to the way PasswordBox works with the NavigationService. If I understand Jared correctly, he solved his problem by stashing the value of the passsword box away before the NavigationService was invoked, and then restored it when his ViewModel was reloaded.

Hi! Great solution. I like it very much. Is there any way to also add some Binding.ValidationRules to it?

2011-10-22T07:12:53.755+01:00

Were you advised not to reference System.Windows.Controls in the ViewModel itself? That is a good principle to try and follow in general. You will, of course need to make use of those controls in your View (in Xaml). But your ViewModel should only concern itself with behaviour, not with how things look. It should communicate with the View almost exclusively using data binding and ICommands.

2011-10-21T22:04:45.324+01:00

I have been advised not to use System.Windows.Controls when you are trying to follow MVVM pattern. Do you agree with this statement? Since I am still learning MVVM pattern, I don’t know why.

2011-08-10T16:35:12.240+01:00

Good stuff. One small change though, in your OnBoundPasswordChanged method, you should be null-checking "box" and checking if GetBindPassword of box is true.

As just a quick note, I believe you get a false positive error reported by ReShaper 5.1 using this code.

I think this is fixed in 6 although I'm not in a position to test it at the moment.

2011-04-08T22:34:07.516+01:00

I am using this code, but I ran into a problem. I am also using Pages and NavigationService. Turns out the NavigationService blanks this password.

So I have a call to the navigation service, and I have to save the password, and replace it afterwards. Thought I would let you know.

Here are the details:
WPF NavigationService blanks PasswordBox.Password, which breaks the MVVM PasswordHelper

@Ross,

Just so you know, it looks like a javascript:void(0) somehow worked its way into your code.

Sam,

Like Ali, i'm not able to use the IDataError interface to validate the password since then NotifyPropertyChanged isn't fired in my VM.

very good work!

But how can i bind ValidationRules?

@Zach: I presume you mean "why would you NOT just inherit from passwordbox"?

The reason is composability. If I implemented my extensions by inheriting from PasswordBox, and you also created some extensions by inheriting from PasswordBox, how would Joe Blogs go about using both our extensions?

However, if we both use attached properties to define the behaviour, Joe Blogs can just give values to both our properties when he uses PasswordBox to activate the behaviours.

Nice article on using attached properties :) Just...

2011-01-21T19:58:45.446Z

Nice article on using attached properties :)

Just a quick question though, why would you just inherit from passwordbox and put these extensions of the class in that way. To me it seems that this static class you have is specific to password box and not a general use class of attached properties and functions.

Thanks!

Hi anonymous, to detect the enter key:
Anonymous:
Just add this in your xaml:
<PasswordBox KeyDown="OnKeyDown"
And add this to your xaml.cs:
private void OnKeyDown(object sender, KeyEventArgs e)
{
if (e.Key == Key.Enter)
{
Submit.Focus();
var peer = new ButtonAutomationPeer(Submit);
var invokeProvider = (IInvokeProvider)peer;
invokeProvider.Invoke();
}
}

Wow, how frustrating that it takes 50+ lines of fairly complex code to do something so simple. I'm all for keeping the UI free from C# code, but not at ANY cost.

To save 2 or 3 lines of code in the UI, you'll add a ton of code somewhere else???
