I've got a WPF ListView with vertical lines using the following style: (sorry for the length, but i thought i should include it)
<SolidColorBrush x:Key="verticalLineColor" Color="Red" />
<Style x:Key="{x:Static GridView.GridViewScrollViewerStyleKey}" TargetType="{x:Type ScrollViewer}">
<Setter Property="Focusable" Value="false"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ScrollViewer}">
<Grid SnapsToDevicePixels="true" Background="{TemplateBinding Background}">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<DockPanel Margin="{TemplateBinding Padding}">
<ScrollViewer Focusable="false" HorizontalScrollBarVisibility="Hidden" VerticalScrollBarVisibility="Hidden" DockPanel.Dock="Top">
<GridViewHeaderRowPresenter x:Name="viewHeaderRowPresenter"
Margin="-2,0,-2,0"
Columns="{Binding Path=TemplatedParent.View.Columns, RelativeSource={RelativeSource TemplatedParent}}"
ColumnHeaderContainerStyle="{Binding Path=TemplatedParent.View.ColumnHeaderContainerStyle, RelativeSource={RelativeSource TemplatedParent}}"
ColumnHeaderTemplate="{Binding Path=TemplatedParent.View.ColumnHeaderTemplate, RelativeSource={RelativeSource TemplatedParent}}"
ColumnHeaderTemplateSelector="{Binding Path=TemplatedParent.View.ColumnHeaderTemplateSelector, RelativeSource={RelativeSource TemplatedParent}}"
AllowsColumnReorder="{Binding Path=TemplatedParent.View.AllowsColumnReorder, RelativeSource={RelativeSource TemplatedParent}}"
ColumnHeaderContextMenu="{Binding Path=TemplatedParent.View.ColumnHeaderContextMenu, RelativeSource={RelativeSource TemplatedParent}}"
ColumnHeaderToolTip="{Binding Path=TemplatedParent.View.ColumnHeaderToolTip, RelativeSource={RelativeSource TemplatedParent}}"
SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" />
</ScrollViewer>
<ScrollContentPresenter x:Name="PART_ScrollContentPresenter"
SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"
ContentTemplate="{TemplateBinding ContentTemplate}"
KeyboardNavigation.DirectionalNavigation="Local"
CanContentScroll="{TemplateBinding CanContentScroll}">
<ScrollContentPresenter.Content>
<Grid>
<!-- Container of vertical and horizontal lines -->
<ItemsControl Margin="-1,0,0,0" ItemsSource="{Binding Path=TemplatedParent.View.Columns, RelativeSource={RelativeSource TemplatedParent}}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Border Width="{Binding Path=ActualWidth}" BorderThickness="0,0,.5,0" BorderBrush="{DynamicResource verticalLineColor}" Opacity="1" />
</DataTemplate>
</ItemsControl.ItemTemplate>
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</ItemsControl>
<ContentControl Content="{TemplateBinding Content}" />
</Grid>
</ScrollContentPresenter.Content>
</ScrollContentPresenter>
</DockPanel>
<ScrollBar Visibility="{TemplateBinding ComputedHorizontalScrollBarVisibility}" Cursor="Arrow" x:Name="PART_HorizontalScrollBar" Grid.Row="1" Maximum="{TemplateBinding ScrollableWidth}" Minimum="0.0" Value="{Binding Path=HorizontalOffset, Mode=OneWay, RelativeSource={RelativeSource TemplatedParent}}" Orientation="Horizontal" ViewportSize="{TemplateBinding ViewportWidth}"/>
<ScrollBar Visibility="{TemplateBinding ComputedVerticalScrollBarVisibility}" Cursor="Arrow" x:Name="PART_VerticalScrollBar" Grid.Column="1" Maximum="{TemplateBinding ScrollableHeight}" Minimum="0.0" Value="{Binding Path=VerticalOffset, Mode=OneWay, RelativeSource={RelativeSource TemplatedParent}}" Orientation="Vertical" ViewportSize="{TemplateBinding ViewportHeight}"/>
<DockPanel Grid.Column="1" Grid.Row="1" Background="{Binding Path=Background, ElementName=PART_VerticalScrollBar}" LastChildFill="false">
<Rectangle Visibility="{TemplateBinding ComputedVerticalScrollBarVisibility}" Width="1" Fill="White" DockPanel.Dock="Left"/>
<Rectangle Visibility="{TemplateBinding ComputedHorizontalScrollBarVisibility}" Height="1" Fill="White" DockPanel.Dock="Top"/>
</DockPanel>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Now, everything works great here. The issue I'm now running into is that I need to shade one of the ListView rows if one of my fields is 0. I've got the following code which gets me 90% of the way there:
<ListView.ItemContainerStyle>
<Style TargetType="{x:Type ListViewItem}">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
<Setter Property="VerticalContentAlignment" Value="Top" />
<Setter Property="Foreground" Value="Black"/>
<Setter Property="Margin" Value="0,-2,0,-1"/>
<Style.Triggers>
<DataTrigger Binding="{Binding QtyInBox}" Value="0">
<Setter Property="Background" Value="LightGray"/>
</DataTrigger>
</Style.Triggers>
</Style>
</ListView.ItemContainerStyle>
Now, the problem I'm running into is that when I set the background, it appears to "overwrite" the grid lines.
Is there any way to get those vertical lines to show through?
EDIT #1: OK, so after playing around for a bit, I'm wondering if this might work; In the following section of code:
<DataTemplate>
<Border Width="{Binding Path=ActualWidth}" BorderThickness="0,0,.5,0" BorderBrush="{DynamicResource verticalLineColor}" />
</DataTemplate>
If I can somehow hook into the Background property there, I should be able to get this working. Can anybody point me in the right direction for binding here? The field I'd need to bind to is QtyInBox on the ItemSource of the ListView.
EDIT #2: Looks like I was wrong there; that seems to be binding the entire column; so I can't set the background of just one row there. Back to the drawing board...
