    <p>I have a problem with updating the value of property from code which is bind to textbox (the textbox is not displaying new value). </p> <p>It was normally working without any problems but in this case source class is in separate assembly (Don't know if it is making any difference).</p> <ol> <li>If I type in textbox the value will be updated in the code </li> <li>When I change the property value directly in code textbox is not displaying new value.</li> <li>After changing the value in textbox one more time the previously set value (in code) is overwritten (so binding is still working).</li> </ol> <p>Additionally I've checked if PropertyChanged event is fired and it is after every change.</p> <p>Any guesses why it's not working? Below corresponding binding and source class.</p> <p>TextBox Text="{Binding Path=Description, Mode=TwoWay}"</p> <pre><code>[DataContract] public class Source : INotifyPropertyChanged { private String _Description; [DataMember] public String Description { get { return _Description; } set { if (_Description == value) return; _Description = value; OnPropertyChanged("Description"); } } public event PropertyChangedEventHandler PropertyChanged; protected virtual void OnPropertyChanged(string propertyName) { PropertyChangedEventHandler handler = this.PropertyChanged; if (handler != null) { var e = new PropertyChangedEventArgs(propertyName); handler(this, e); } } } </code></pre> <p>I've Fix the problem it was not connected to different assembly obviously. I have a bug in setting value to property.</p>

    1. COHave you tried putting a break point in OnPropertyChanged and seeing if anything is attached to the PropertyChanged event? This should tell you if the TextBox is being notified.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
