Showing Plain Text of a Password TextBox in C#

Question

I am having a textbox for password field, I want to add a Checkbox that toggles the password into plain text.

I did the following coding for it.

txtpwd.PasswordChar = (char)(byte)32;

but this simply hides not showing the plain text of what is typed in textbox field.

any body can help?

WPF has some pitfals. [According To StackOverFlowPost][1] [1]: http://stackoverflow.com/questions/832470/wpf-font-why-are-some-characters-missing — DareDevil, Oct 22 '13 at 12:31

Here is the solution, I added CheckBox with name chkpwd and on its CheckedChange event i added this code

private void chkpwd_CheckedChanged(object sender, EventArgs e)
    {
        if (chkpwd.Checked)
            txtpwd.PasswordChar = '\0';
        else
            txtpwd.PasswordChar = '*';
    }

This will show plain text when checkbox's checked property true

I try to use code you provided for WPF, but when I set `txtpwd.PasswordChar = '\0'` I got [squares](http://clip2net.com/s/60Er27) inside password box. How to fix this ? – Alezis Oct 22 '13 at 12:17
Well I didn't work with WPF. I will see. – DareDevil Oct 22 '13 at 12:21

what did you find? I found many links as well, but haven't seen any solution which works with `txtpwd.PasswordChar = '\0'` for WPF. Please share your link. – Alezis Oct 22 '13 at 12:36

Only if UseSystemPassword is false. This doesn't work if it's true. – Scott Shaw-Smith Apr 23 '15 at 16:30
