XAML - PasswordBox

A PasswordBox is a control in which the user can enter a masked password. When the user enters a password, the text is not displayed, only the password characters are shown. The password character (usually shown as *) can be easily changed by the PasswordChar property. The hierarchical inheritance of PasswordBox class is as follows −

The following example shows the PasswordBox, labels, and a button. Here is the XAML code to create and initialize all these controls.

<Window x:Class = "PasswordBox.MainWindow" 
   xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation"
   xmlns:x = "http://schemas.microsoft.com/winfx/2006/xaml"
   Title = "MainWindow" Height = "350" Width = "604">
 
   <Grid> 
      <PasswordBox x:Name = "pwBox" 
         Height = "35" 
         Width = "200"
         MaxLength = "8" 
         Margin = "159,55,158,229" /> 
      <Label Content = "Password" 
         HorizontalAlignment = "Left" 
         Margin = "108,61,0,0" 
         VerticalAlignment = "Top" 
         Width = "70" /> 
      <Button Content = "Ok" HorizontalAlignment = "Left" 
         Margin = "406,64,0,0" 
         VerticalAlignment = "Top" 
         Width = "75" Click = "Button_Click"/> 
      <Label Name = "statusText" 
         HorizontalAlignment = "Left" 
         Margin = "159,128,0,0" 
         VerticalAlignment = "Top" 
         Width = "200" 
         Height = "38"/> 
   </Grid> 
</Window>

Here is the button click event implementation in C# in which the program compares the password. If the entered password is “xaml1234”, then it will display the message "correct password" on the label.

using System.Linq; 
using System.Windows; 
using System.Windows.Controls;

namespace XAMLMenu {
   public partial class MainWindow : Window { 
      public MainWindow() { 
         InitializeComponent(); 
      }
      private void MenuItem_Click(object sender, RoutedEventArgs e) { 
         MenuItem item = sender as MenuItem; 
        this.Title = "File: " + item.Header; 
      } 
      private void MenuItem_Click1(object sender, RoutedEventArgs e) { 
         MenuItem item = sender as MenuItem; 
         this.Title = "Edit: " + item.Header; 
      } 
   } 
}

When you compile and execute the above code, it will produce the following output −

We recommend you to execute the above example code and experiment with some other properties and events.
