Trigger a password behavior on and off in a textbox

Question

I have a textbox that I'm using as a password box, and I want to have the default password visible, and then when it is changed, hide it with '*'. So when the user opens the form, the Password text box will already have "welcome1" in the text box, but when they change it, the password will appear as "*".

What I have at the moment:

if (txtPassword.Text == "welcome1")
{
    // Set txtPassword.PasswordChar to null or empty.
}
else { txtPassword.PasswordChar = '*'; }

Answer 1

To reset the password character to not mask, set it to the null character:

txtPassword.PasswordChar = '\0';

Default value specified on MSDN

Answer 2

Nevermind, just figured it out:

private void txtPassword_TextChanged(object sender, EventArgs e)
{
    if (txtPassword.Text != "welcome1")
    {
        txtPassword.PasswordChar = '*';
    }
}

Answer 3

Maybe use 2 text boxes. 1e Visible true 2e Visible false And set the 2e text box Password Char to * With a mouse click event on the first text box. When somebody clicks the text box to type a password the text box changes.

    private void textBox1_MouseClick(object sender, MouseEventArgs e)
    {
        textBox1.Text = "";
        textBox1.Visible = false;
        textBox2.Visible = true;
        textBox2.Focus();
    }

Also put a form mouse click for if thy didn't type a text , go back to text box 1 or something like that.

    private void Form1_MouseClick(object sender, MouseEventArgs e)
    {
        if (textBox2.Text == "")
        {
            textBox2.Visible = false;
            textBox1.Visible = true;
            textBox1.Text = "Welcome1";
        }
    }
