Can't use button to disable UseSystemPasswordChar

Question

Hi there,

I got a problem on my project: when i try to to turn false UseSystemPasswordChar, the password does not turn to letter and stay like that • .

I try with every buttons (MaterialSkin and Windows). But if i used radio button, it's functionnal

Does someone know how to solve this ?

Answer 1

You haven't provided any code or screenshots so it is hard to understand what you mean by using every button and radio button. None of these seem applicable to a TextBox's UseSystemPasswordChar which I'm also assuming you're talking about.

Assuming you just want to show/hide a password then set UseSystemPasswordChar to true to hide the password and false to show it.

   private void button1_Click ( object sender, EventArgs e )  
   {  
       //Toggle password  
       if (textBox1.UseSystemPasswordChar)  
       {  
           textBox1.UseSystemPasswordChar = false;  
       } else  
           textBox1.UseSystemPasswordChar = true;  
   }  

But if you want to use a custom password char then you need to set PasswordChar instead. If it is NULL (meaning '\0') then no password char is shown.

   private void button1_Click ( object sender, EventArgs e )  
   {  
       //Toggle password  
       if (textBox1.PasswordChar != '\0')  
       {  
           textBox1.PasswordChar = '\0';  
       } else  
           textBox1.PasswordChar = 'x';  
   }  

Note that if you try to combine the two approaches then you need to toggle them both as well but you should really be using one or the other.

The following is the same as @Michael Taylor just package differently.

public static class TextBoxExtensions  
{  
    public static void ToggleShow(this TextBox sender, bool show = true, char hideWith = '\u25CF')  
    {  
        sender.PasswordChar = show ? '\0' : hideWith;  
    }  
}  

In a form

using System;  
using System.Windows.Forms;  
  
namespace PassDemo  
{  
    public partial class Form1 : Form  
    {  
        private const char _hideChar = '\u25CF';  
  
        public Form1()  
        {  
            InitializeComponent();  
            PasswordTextBox.PasswordChar = _hideChar;  
        }  
  
        private void ToggleCheckBox_CheckedChanged(object sender, EventArgs e)  
        {  
            PasswordTextBox.ToggleShow(ToggleCheckBox.Checked, _hideChar);  
        }  
    }  
}

Hi everyone,

so my code is the following:

using MaterialSkin.Controls;  
using MyPasswordManager.Helper;  
  
namespace MyPasswordManager  
{  
    public partial class NewDatabaseForm : MaterialForm  
    {  
        public NewDatabaseForm()  
        {  
            InitializeComponent();  
        }  
        private void TogglePasswords(object sender, EventArgs e)  
        {  
            //Toggle password  
            if (setPassword_TxtBx1.UseSystemPasswordChar)  
            {  
                setPassword_TxtBx1.UseSystemPasswordChar = false;  
            }  
            else  
                setPassword_TxtBx1.UseSystemPasswordChar = true;  
        }  
    }  
}  

The winform looks like this:

Hi everyone.

My problem is solved. Since the next update, MaterialSkin TextBox got a new property named Password. So when i activate it, it's like the UsePasswordChar on Windows TextBox.

Thank you all for your answers and your help !
