how to create WPF User Control?

[Sherin]

the XAML code in which a button and a text box is created with some properties in MyUserControl.xaml file.

<UserControl x:Class = "WPFUserControl.MyUserControl" 
   xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
   xmlns:x = "http://schemas.microsoft.com/winfx/2006/xaml" 
   xmlns:mc = "http://schemas.openxmlformats.org/markup-compatibility/2006"  
   xmlns:d = "http://schemas.microsoft.com/expression/blend/2008"  
   mc:Ignorable = "d" d:DesignHeight = "300" d:DesignWidth = "300"> 
 
   <Grid> 
      <TextBox Height = "23"  
         HorizontalAlignment = "Left"  
         Margin = "80,49,0,0" Name = "txtBox"  
         VerticalAlignment = "Top" Width = "200" /> 
 
      <Button Content = "Click Me"  
         Height = "23" HorizontalAlignment = "Left"  
         Margin = "96,88,0,0" Name = "button"  
         VerticalAlignment = "Top" Click = "button_Click" />    
   </Grid>
 
</UserControl>

Given below is the C# code for button click event in MyUserControl.cs file which updates the text box.

using System; 
using System.Windows; 
using System.Windows.Controls; 
 
namespace WPFUserControl {
   /// <summary>
      /// Interaction logic for MyUserControl.xaml 
   /// </summary> 
 
   public partial class MyUserControl : UserControl { 
 
      public MyUserControl() { 
         InitializeComponent(); 
      }  
 
      private void button_Click(object sender, RoutedEventArgs e) { 
         txtBox.Text = "You have just clicked the button"; 
      } 
   } 
}

Here is the implementation in MainWindow.xaml to add the user control.

<Window x:Class = "XAMLUserControl.MainWindow" 
   xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
   xmlns:x = "http://schemas.microsoft.com/winfx/2006/xaml" 
   xmlns:control = "clr-namespace:WPFUserControl" 
   Title = "MainWindow" Height = "350" Width = "525"> 
 
   <Grid> 
      <control:MyUserControl/> 
   </Grid> 
 
</Window>
