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 Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:Table Normal; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:Calibrisans-serif; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:Times New Roman; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin;} 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
