    copied!<p>How can I use a property trigger in a style (or another method) to change a property (ToolTip for example) that already has its value defined by a binding?</p> <p>I have a simple button like so:</p> <pre><code>&lt;Button Name="Button1" Style="{StaticResource ButtonStyle}" ToolTip="{Binding Name}" &gt;My Button&lt;/Button&gt; </code></pre> <p>It has a binding on the tooltip to show the Name property of the class set as DataContext.</p> <p>My problem is I want to show the Name when the button is enabled, but something else when it is disabled. I thought I could get around my problem with a style and a trigger like so:</p> <pre><code>&lt;Style TargetType="Button" x:Key="ButtonStyle"&gt; &lt;Setter Property="ToolTipService.ShowOnDisabled" Value="True" /&gt; &lt;Style.Triggers&gt; &lt;Trigger Property="IsEnabled" Value="false"&gt; &lt;Setter Property="ToolTip" Value="Disabled" /&gt; &lt;/Trigger&gt; &lt;/Style.Triggers&gt; &lt;/Style&gt; </code></pre> <p>But this doesn't work. If I removed the tooltip binding from the button then I do get the correct tooltip when the button is disabled. But it seems I can't have both a binding and a trigger on the same property.</p> <p>I could get around it by adding another trigger like so:</p> <pre><code>&lt;Trigger Property="IsEnabled" Value="true"&gt; &lt;Setter Property="ToolTip" Value="{Binding Name}" /&gt; &lt;/Trigger&gt; </code></pre> <p>But I would like to use the style for 4 or 5 buttons that will all have different bindings for the enabled ToolTip, but the same (fixed) tooltip when they are disabled.</p> <p>Any suggestions?</p>
