How to make a WPF TextBox use password characters?
Or use 'password font'. A font that shows all characters as dots. Remember to disable cut and copy clipboard functions.
There's a new control in WPF designed for passwords, it's called PasswordBox
. You should use that instead of a TextBox
if you need to mask the input.
Here's a brief article about it. To retrieve the value that was entered, use the Password property.
EDIT: You've pretty much asked a new question - how can you unmask the text in a WPF PasswordBox? To the best of my knowledge you can't, though you could of course display it in a regular TextBox on demand by getting the value of the password from PasswordBox.Password
Databinding to a PasswordBox
isn't possible without a custom helper class - though this would reduce the increased security offered by the new PasswordBox
control (as described here). With that considered, this article includes a section on creating a helper class that allows you to databind to a PasswordBox
.
You have to use PasswordBox
instead of TextBox
:
<PasswordBox Height="42" Width="200" Margin="22,28,28,0"
Name="passwordBox1" VerticalAlignment="Top"
Background="LightBlue" Foreground="DarkBlue"
MaxLength="25" PasswordChar="*"
/>
