  1. POTroubles with GoToStateAction
    text
    copied!<p>I have had several problems with the GoToStateAction in different scenarios, and I'm beginning to believe that either the feature is buggy, or that my understanding of it is off.</p> <p>In this case, I have a datatemplate with an ellipse that is representing a connector. The connector has an IsConnected property... I am using VisualStates and the GoToStateAction with a DataTrigger to switch between the 2 states 'Connected' and 'NotConnected'. However, in this case the state is never set.</p> <p>I know the model is set up correctly, as trying other binding scenarios with IsConnected works fine. What am I doing wrong?</p> <pre><code>&lt;DataTemplate x:Key="ConnectorTemplate"&gt; &lt;Grid x:Name="grid"&gt; &lt;VisualStateManager.VisualStateGroups&gt; &lt;VisualStateGroup x:Name="ConnectionStates"&gt; &lt;VisualState x:Name="Connected"&gt; &lt;Storyboard&gt; &lt;ColorAnimation Duration="0" To="#FFEAFFDD" Storyboard.TargetProperty="(Shape.Fill).(GradientBrush.GradientStops)[1].(GradientStop.Color)" Storyboard.TargetName="ellipse" d:IsOptimized="True"/&gt; &lt;ColorAnimation Duration="0" To="#FF56992B" Storyboard.TargetProperty="(Shape.Fill).(GradientBrush.GradientStops)[0].(GradientStop.Color)" Storyboard.TargetName="ellipse" d:IsOptimized="True"/&gt; &lt;/Storyboard&gt; &lt;/VisualState&gt; &lt;VisualState x:Name="NotConnected"/&gt; &lt;/VisualStateGroup&gt; &lt;/VisualStateManager.VisualStateGroups&gt; &lt;VisualStateManager.CustomVisualStateManager&gt; &lt;ei:ExtendedVisualStateManager/&gt; &lt;/VisualStateManager.CustomVisualStateManager&gt; &lt;Ellipse x:Name="ellipse" Height="8" Width="8"&gt; &lt;i:Interaction.Triggers&gt; &lt;ei:DataTrigger Binding="{Binding IsConnected}" Value="true"&gt; &lt;ei:GoToStateAction StateName="Connected"/&gt; &lt;/ei:DataTrigger&gt; &lt;ei:DataTrigger Binding="{Binding IsConnected}" Value="false"&gt; &lt;ei:GoToStateAction StateName="NotConnected"/&gt; &lt;/ei:DataTrigger&gt; &lt;/i:Interaction.Triggers&gt; &lt;Ellipse.Fill&gt; &lt;RadialGradientBrush Center="0.275,0.262" GradientOrigin="0.275,0.262" RadiusX="0.566" RadiusY="0.566"&gt; &lt;GradientStop Color="#FF333333" Offset="1" /&gt; &lt;GradientStop Color="#FFC4C4C4" /&gt; &lt;/RadialGradientBrush&gt; &lt;/Ellipse.Fill&gt; &lt;/Ellipse&gt; &lt;/Grid&gt; &lt;/DataTemplate&gt; </code></pre>
