    <p>I am trying to use a ToggleSwitch with MVVM Light in a Wp7 app.</p> <p>In the view I have:</p> <pre><code>&lt;toolkit:ToggleSwitch x:Name="toggleAccuracy" Content="{Binding AccuracyText, Mode=TwoWay}" IsChecked="{Binding AccuracyHigh, Mode=TwoWay}" IsEnabled="True" Header="Accuracy" Margin="8,0" Height="140" VerticalAlignment="Top" &gt; </code></pre> <p>The ViewModel contains:</p> <pre><code>private bool _AccuracyHigh = true; public bool AccuracyHigh { get { return _AccuracyHigh; } set { _AccuracyHigh = value; } } private string _AccuracyText = "High"; public string AccuracyText { get { return _AccuracyText; } set { _AccuracyText = value; } } </code></pre> <p>AccuracyText and AccuracyHigh fire to get the appropriate values. </p> <p>My difficulty is trying to trap the "state changed" event; Checked and Unchecked. If I bind these with something like: Checked="{Binding Path=AccuracyChanged}" I get a runtime error telling me the markup is wrong.</p> <p>I also unsuccessfully tried a trigger:</p> <pre><code> &lt;i:Interaction.Triggers&gt; &lt;i:EventTrigger EventName="Checked"&gt; &lt;GalaSoft_MvvmLight_Command:EventToCommand Command="{Binding AccuracyChanged}"/&gt; &lt;/i:EventTrigger&gt; &lt;/i:Interaction.Triggers&gt; &lt;/toolkit:ToggleSwitch&gt; </code></pre> <p>I could use RadioButton which work just fine with </p> <pre><code>&lt;RadioButton Content="Up" x:Name="radioButton1" GroupName="UpDown" Width="119" /&gt; &lt;RadioButton IsChecked="{Binding UpDown, Mode=TwoWay}" Content="Down" x:Name="radioButton2" GroupName="UpDown" /&gt; public bool UpDown { get { bool ud = settings.UpDown.ToLower() == "u" ? true : false; return ud; } set { settings.UpDown = value == true ? "U" : "D"; settings.Save(); } } </code></pre> <p>but a ToggleSwitch looks better (IMHO)</p> <p>Any suggestions appreciated.</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.
