I am applying a ItemContainerStyle
to a ListBox
control. In my ListBoxItem
style I have several triggers containing storyboard animations that apply to the current state of the ListBoxItem
(IsSelected
, IsMouseOver
).
It all works fine and dandy until after I have selected a ListBoxItem
, then the IsMouseOver
storyboard animation isn't fired for the ListBoxItem
which was previously selected.
I can't see where the problem is, so I am hoping someone will help me out with this issue.
Cheers
Here is the code I am using
<Style x:Key="ListBoxFeedItemStyle" TargetType="{x:Type ListBoxItem}">
<Setter Property="Background" Value="Transparent"/>
<Setter Property="HorizontalContentAlignment" Value="{Binding HorizontalContentAlignment, RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}"/>
<Setter Property="VerticalContentAlignment" Value="{Binding VerticalContentAlignment, RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}"/>
<Setter Property="Padding" Value="2,0,0,0"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListBoxItem}">
<Border x:Name="Bd" Background="{TemplateBinding Background}" Margin="5" SnapsToDevicePixels="true">
<Grid Name="Grid" Height="Auto" Margin="5">
<TextBlock Margin="10" Text="{Binding Path=Name}" FontSize="14" TextTrimming="CharacterEllipsis" />
</Grid>
</Border>

Check the order of your Triggers. Have a look at Multiple storyboards on one property
