WPF PasswordBox Caret

Question

Is there a way to hide or move the PasswordBox's caret?

Answer 1

In .NET 3.5 SP1 or previous, there is no clean way to specify the color of a WPF TextBox/PasswordBox caret.

However, there is a way to specify (or in this case remove) that caret from view (via a hack). The caret color is the inverse color of the TextBox/PasswordBox's background color. THus, you can make the background color "transparent black", which will fool the system into using a white caret (which is not visible).

The code is (simply) as follows:

<PasswordBox Background="#00000000" />

Note that in .NET 4.0 the Caret will be customizable.

Hope this helps!
