  1. POBuilding a EventTriggerBehavior that supports my own customized events
    text
    copied!<p>I built my own UserControl (that I consume from a separate assembly) with its own customized events, in the parent project I want to use those events with <strong>Commands</strong> since it's an <strong>MVVM</strong> application, all by using the <a href="http://msdn.microsoft.com/en-us/library/windows/apps/dn457340.aspx" rel="nofollow">Behaviors SDK (XAML) for Visual Studio 2013</a>, as follows :</p> <pre><code>&lt;mediaPlayerControl:PlayerControl&gt; &lt;interactivity:Interaction.Behaviors&gt; &lt;core:EventTriggerBehavior EventName="ForwardClicked"&gt; &lt;core:InvokeCommandAction Command="{Binding OnForwardClicked, Mode=TwoWay}"/&gt; &lt;/core:EventTriggerBehavior&gt; &lt;/interactivity:Interaction.Behaviors&gt; &lt;/mediaPlayerControl:PlayerControl&gt; </code></pre> <p>The problem is that the EventTriggerBehavior supports only some specific events as mentioned <a href="http://msdn.microsoft.com/en-us/library/windows/apps/dn469361.aspx" rel="nofollow">here</a>, hence the commands I'm using on my events don't fire, now, what I want to do is, to build behaviors that provide the same experience, and that support my own event: I want them to look similar to this :</p> <pre><code>&lt;mediaPlayerControl:PlayerControl&gt; &lt;interactivity:Interaction.Behaviors&gt; &lt;core:ExtensionsEventTriggerBehavior EventName="ForwardClicked"&gt; &lt;core:ExtensionsInvokeCommandAction Command="{Binding OnForwardClicked, Mode=TwoWay}"/&gt; &lt;/core:EventTriggerBehavior&gt; &lt;/interactivity:Interaction.Behaviors&gt; &lt;/mediaPlayerControl:PlayerControl&gt; </code></pre> <p>I've read many articles about implementing such behaviors, but I couldn't get it clear for me since it's the first time I deal with them this way, I would like if you show me how to do.</p>
