  1. POMultiTrigger: Combined DataTrigger and PropertyTrigger not working
    text
    copied!<p>I have a problem where I need to combine a <code>DataTrigger</code> and a <code>PropertyTrigger</code> into a <code>MultiDataTrigger</code> to show an <code>Image</code> in a <code>GridViewColumn</code> (combined with a <code>TreeView</code>, it's a custom control I'm using). I experimented and searched some thins on the internet and this is how far I've come:</p> <pre><code> &lt;Image Width="16" Height="16" Stretch="UniformToFill"&gt; &lt;Image.Style&gt; &lt;Style TargetType="{x:Type Image}"&gt; &lt;Setter Property="Source" Value="{Binding ScorecardNiveau, Converter={StaticResource ScorecardNiveauToImageConverter}}" /&gt; &lt;Style.Triggers&gt; &lt;MultiDataTrigger&gt; &lt;MultiDataTrigger.Conditions&gt; &lt;Condition Binding="{Binding WpfSettings.IsExpanded}" Value="True" /&gt; &lt;Condition Binding="{Binding RelativeSource={RelativeSource Self}, Path=Source}" Value="/folder_closed.png" /&gt; &lt;/MultiDataTrigger.Conditions&gt; &lt;Setter Property="Source" Value="/folder_open.png" /&gt; &lt;/MultiDataTrigger&gt; &lt;/Style.Triggers&gt; &lt;/Image.Style&gt; &lt;/Image&gt; </code></pre> <p>Now, initially, the <code>Image</code> can have two images, according to the <code>Converter</code>. Either the folder_open, or another one (not important now). Now what I want is: when the TreeViewNode is expanded (<code>WpfSetting.IsExpanded = true</code>) and when the Image Source is folder_closed, I want the Image to get the folder_open image. I think I am close with the above code, but it's not really working. The <code>Image</code> isn't changing at all when I open a <code>TreeViewNode</code>.</p> <p>I think I am doing something wrong with the Condition on the <code>RelativeSource=Self</code>, but I am not sure.</p> <p>Anyone who can help me please? Thanks in advance.</p> <p>Of course, more information/code can be provided if needed.</p>
