How to make password box non-editable in wpf

Question

I need to make password box as non-editable in wpf. I used
IsEnabled = false

But it is affecting my style some blur effect came because of that... Is there any other way to achieve this ?

Answer 1

You can handle the PreviewTextInput event, preventing the user from entering text. Like so:

Xaml:

<PasswordBox PreviewTextInput="HandleInput"/>

Codebehind:

private void HandleInput(object sender, TextCompositionEventArgs e) {
  e.Handled = true;
}

Answer 2

One solution is to make a custom functionality to mimic the IsReadOnly .

There are couple things to take care of - eg clipboard pasting also.

You'll get similar behavior by defining some attached property (eg IsPasswordReadOnly or just the same) - which would work out all that's required.

Here is a good starting example - which could, should I think work for Password box as well - but I haven't tried it and you gotta test yourself.

Readonly textbox for WPF with visible cursor (.NET 3.5)

You'd have to replace references to TextBox with PasswordBox , rename it to IsReadOnly - and I think the rest might work the same.

And you use it like...

<PasswordBox my:AttachReadOnly.IsReadOnly="True" />

Answer 3

我知道这已经两年了，但是我有相同的需求并以这种方式解决了这两个问题：这两个属性的组合都设置为false，将阻止控件中的输入/编辑，而不会影响所需的样式： ，IsHitTestVisible

Answer 4

Pretty simple..

Set an event handler for PreviewTextInput in your XML like so:

    PreviewTextInput="PasswordBoxOnPreviewTextInput"

And within that method:

    private void PasswordBoxOnPreviewTextInput(object sender, TextCompositionEventArgs e)
    {
        if (m_DisablePasswordBox)
            e.Handled = true;
    }

It will now prevent you from typing anything in :)
