    <p>Someone please help. I have an interesting issue. I am trying to implement an MVVM app and I want to bind to radiobuttons in my view. </p> <p>Here's my view:</p> <pre><code>&lt;StackPanel Orientation="Horizontal" Grid.ColumnSpan="2" &gt; &lt;RadioButton GroupName="1" IsChecked="{Binding Path=NoteGeneral, Mode=TwoWay}"&gt;General&lt;/RadioButton&gt; &lt;RadioButton GroupName="1" IsChecked="{Binding Path=NoteContact, Mode=TwoWay}" &gt;Contact&lt;/RadioButton&gt; &lt;RadioButton GroupName="1" IsChecked="{Binding Path=NoteAddress, Mode=TwoWay}" &gt;Address&lt;/RadioButton&gt; &lt;RadioButton GroupName="1" IsChecked="{Binding Path=NotePhone, Mode=TwoWay}" &gt;Phone&lt;/RadioButton&gt; &lt;/StackPanel&gt; </code></pre> <p>Here's my ViewModel:</p> <pre><code> bool _NoteGeneral; public bool NoteGeneral { get { return _NoteGeneral; } set { _NoteGeneral = value; OnPropertyChanged("NoteGeneral"); } } bool _NoteContact; public bool NoteContact { get { return _NoteContact; } set { _NoteContact = value; OnPropertyChanged("NoteContact"); } } bool _NoteAddress; public bool NoteAddress { get { return _NoteAddress; } set { _NoteAddress = value; OnPropertyChanged("NoteAddress"); } } bool _NotePhone; public bool NotePhone { get { return _NotePhone; } set { _NotePhone = value; OnPropertyChanged("NotePhone"); } } </code></pre> <p>The problem is this, when I click the different radiobuttons the property setter only gets called the first time(when i run thru debugging). e.g. When I click NoteGeneral, NoteContact, then NoteGeneral again only the first two clicks update my viewmodel. I think I might have something wrong with my binding, or maybe I'm approaching this the completely wrong way. </p> <p>Can anyone help?</p> <p>How should I implement radiobutton selections in my viewmodel?</p> <h2>.NET 4 and Later</h2> <p>This issue with RadioButton binding was resolved by Microsoft when .NET 4 was released. Binding of RadioButtons now works as you would expect without any of the work-arounds listed below.</p>

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.
