RE: Style trigger not firing in wpf app

Hi Moondaddy,

This is a quick note to let you know that I'm performing research on this
issue and will get back to you ASAP.

I appreciate your patience!

Hi Moondaddy,

After doing some research, I figure the problem out.

The main point is that the DataTrigger you use in the
"ConnectionGroupStyle" is not correct. You should use the relative source
mode of FindAncestor to get notified when the IsMouseOver property of the
parent element of the ChildControl changes.

In addition, in the SomeControl.xaml file, you shouldn't set the Visibility
property explicitly because it will override the style that is applied to
the element. You should set the initial value of the Visibility property in
the style.

The modifications are as follows.

1. In the Dictionary1.xaml:

<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:c="clr-namespace:StyleTriggerFromParent">

<Style x:Key="ConnectionGroupStyle" TargetType="{x:Type
c:ChildControl}">
<Setter Property="SnapsToDevicePixels" Value="false"/>
<Setter Property="Visibility" Value="Hidden"/>
<Style.Triggers>
<DataTrigger Value="True">
<DataTrigger.Binding>
<Binding Path="IsMouseOver">
<Binding.RelativeSource>
<RelativeSource Mode="FindAncestor"
AncestorType="{x:Type FrameworkElement}" AncestorLevel="1"/>
</Binding.RelativeSource>
</Binding>
</DataTrigger.Binding>
<Setter Property="Visibility" Value="Visible" />
</DataTrigger>
</Style.Triggers>
</Style>

</ResourceDictionary>

2. In the SomeControl.xaml, remove the Visibility property from the
ChildControl element.

Please try my suggestion and let me know the result.
