My styles are leaking

[DanThMan]

I wrote a style in XAML that applies a DropShadowBitmapEffect to some
DockPanels in my Window. This works great. The problem is that, thanks
to property value inheritance, now *everything* inside these
DockPanels has a drop shadow.

I generally like property value inheritance, but I would like to turn
it off in this case. Is that even possible? If not, how do I insert a
"default bitmap effect" or "null bitmap effect" into the styles for
controls lower in the tree?

To reiterate, I want to know how to make a container have a drop
shadow without all the items in the container having a drop shadow.

Thanks very much for your help,

Dan,

What is the XAML that you are using to apply the style? Something tells
me that you are not discriminating too much in how you are applying the
style.

Hi Nicholas,

Here is my Style definition:


<Style x:Key="DockPanelStyle" TargetType="DockPanel">
<Setter Property="Background" Value="LightSteelBlue" />
<Setter Property="Opacity" Value="0.75" />
<Setter Property="BitmapEffect">
<Setter.Value>
<DropShadowBitmapEffect Color="Black" Direction="315"
ShadowDepth="5" />
</Setter.Value>
</Setter>
</Style>

And here is one of my DockPanels where everything is getting "drop
shadowed":

<DockPanel Style="{StaticResource DockPanelStyle}" Grid.Row="0"
Grid.Column="0" Grid.ColumnSpan="3">
<Label Style="{StaticResource HeadingLabel}"
DockPanel.Dock="Top">Team Map</Label>
<Grid Style="{StaticResource InnerGridStyle}">
<ListView Name="TeamMapListView" ItemsSource="{Binding
Path=DefaultView}">
<ListView.View>
<GridView AllowsColumnReorder="True">
<GridViewColumn Header="Contact" CellTemplate="{Binding
Path=ContactName}" />
<GridViewColumn Header="Current Role"
DisplayMemberBinding="{Binding Path=CurrentRole}" />
<GridViewColumn Header="Dominant Role"
DisplayMemberBinding="{Binding Path=DominantRole}" />
</GridView>
</ListView.View>
</ListView>
</Grid>
</DockPanel>

Thx,

Dan,

I believe it has to do with how you declare your TargetType. I think
you should be doing this:

<Style x:Key="DockPanelStyle" TargetType="{x:Type DockPanel}">

Dan,

Also, you should specify a TargetType or a Key for the style, not both,
so remove the Key attribute if you want to apply it to all elements of a
particular type, or remove the TargetType attribute if you only want to
apply it to a single, named instance.

Thanks, but I get the exact same result if I do this.

Removing the TargetType generates an error:

I guess it's just a designer issue. I'm not having this problem if I
run it.
