    text
    copied!<p>In a WPF Application, I have a ViewModel that is exposing a collection of strings that I'm displaying as buttons through an ItemsControl container using a WrapPanel. I haven't been able to bind the RelayCommand in my ViewModel to the buttons, however.</p> <p>ViewModel (IncidentAddressesViewModel):</p> <pre><code>public IEnumerable&lt;string&gt; Addresses { get; set; } public RelayCommand&lt;string&gt; ZoomToAddressCommand { get { if (this.zoomToAddressCommand == null) this.zoomToAddressComamnd = new RelayCommand&lt;string&gt;(this.ZoomToAddress); return this.zoomToAddressCommand; }} private void ZoomToAddress(string address) { MessageBox.Show (address); } </code></pre> <p>XAML:</p> <pre><code>&lt;TabItem x:Name="IncidentAddressesTab"&gt; &lt;ItemsControl ItemsSource="{Binding Addresses}"&gt; &lt;i:Interaction.Triggers&gt; &lt;i:EventTrigger EventName="Command"&gt; &lt;cmd:EventToCommand Command="{Binding ZoomToAddressCommand}" CommandParameter="{Binding Text}" PassEventArgsToCommand="True" /&gt; &lt;/i:EventTrigger&gt; &lt;/i:Interaction.Triggers&gt; &lt;ItemsControl.ItemsPanel&gt; &lt;ItemsPanelTemplate&gt; &lt;WrapPanel Orientation="Vertical"/&gt; &lt;/ItemsPanelTemplate&gt; &lt;/ItemsControl.ItemsPanel&gt; &lt;ItemsControl.ItemTemplate&gt; &lt;DataTemplate&gt; &lt;Button Content="{Binding}" /&gt; &lt;/DataTemplate&gt; &lt;/ItemsControl.ItemTemplate&gt; &lt;/ItemsControl&gt; &lt;/TabItem&gt; </code></pre> <p>Xaml Code Behind that connects the DataContext</p> <pre><code>IncidentAddressesTab.DataContext = new IncidentAddressesViewModel(); </code></pre> <p>The buttons are showing with the addresses. When I set a breakpoint at the ZoomToAddressCommand, it does get hit once, but when I click the buttons, the ZoomToAddress method never gets invoked.</p> <p>UPDATE to include binding details: I am actually binding to the TabItem. I have updated the XAML to include the additional tag and added the binding code in the XAML Code Behind. I didn't know this was pertinent information or I would have added it in the beginning..
