Notify custom property changes

Thank you so much for your response. How do I detect the Usercontrol's OnPropertyChaged event in Xaml Window though? I guess I am stuck because property belongs to usercontrol and not to some class. What I mean by that is , refering to your example, you have created public event on ModelNumber property of product class. But in my case I have created public property to usercontrol.
Here is the code
UC_TestClient.xaml.cs
namespace Test
{
     public partial class UC_TestClient : UserControl
       {
           public bool bDirty {get; set;}
Window1.xaml.cs
namespace Test
 {
    public partial class Window1 : Window
       {
          public bool bDirty_Window { get; set;} 
Sorry I am not much familliar with C#

Hi

It's simple in WPF, here just sample code to dot, you need inherit your class from the INotifyPropertyChanged

using System;

using System.Collections.Generic;

using System.Text;

using System.ComponentModel;

 

namespace StoreDatabase

{

      public class Product : INotifyPropertyChanged

      {

            private string modelNumber;

            public string ModelNumber

            {

                  get { return modelNumber; }

                  set {

                modelNumber = value;

                OnPropertyChanged(new PropertyChangedEventArgs("ModelNumber"));

            }

            }             

 

           

 

        public event PropertyChangedEventHandler PropertyChanged;

        public void OnPropertyChanged(PropertyChangedEventArgs e)

        {

            if (PropertyChanged != null)

                PropertyChanged(this, e);

        }

                      

}

 

Same way make your property and and control then you can look work cool

thank you
