Hello,
I've applied the WMP11 style to my grid and have added a number of styles. For example, a different mouse over brush and alternating row brushes
<Style TargetType="{x:Type DataGrid:DataRow}">
<Setter Property="Background" Value="{DynamicResource DefaultRowBackgroundBrush}" />
<Setter Property="Foreground" Value="White"/>
<Style.Triggers>
<DataTrigger Binding="{Binding Path=(DataGrid:DataGridVirtualizingPanel.ItemIndex), Converter={StaticResource rowIndexConverter}, RelativeSource={RelativeSource Self}}"
Value="True">
<Setter Property="Background" Value="{DynamicResource AlternateRowBackgroundBrush}" />
</DataTrigger>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="{DynamicResource MouseOverRowBackgroundBrush}" />
</Trigger>
</Style.Triggers>
</Style>
What I'd like to do now is customise the way the ColumnHeaders are rendered by taking away the curved rectangle when it is moused over. I have found the parts of the theme where this effect is created:
<ControlTemplate x:Key="tableViewColumnManagerCellTemplate" TargetType="{x:Type ColumnManagerCell}">
...
<Grid Name="mgrCellmainGrid" Height="33" Margin="0,4,0,0">
<Grid.RowDefinitions>
<RowDefinition Height="3*" />
<RowDefinition Height="4*" />
</Grid.RowDefinitions>
<Border Name="mgrCellborderBack" BorderThickness="1" CornerRadius="5,5,0,0" RowSpan="2" />
<Border Name="mgrCellborderBackHotBlue" BorderThickness="1" CornerRadius="5,5,0,0" Opacity="0" RowSpan="2" Background="{StaticResource rowSelectorBackgroundBrush}" />
<Border Name="mgrCellborderTopGradient" CornerRadius="5,5,0,0" Margin="1" Row="0" />
<Border Name="mgrCellborder3" BorderBrush="#FFFFFF" BorderThickness="1" CornerRadius="5,5,0,0" Opacity="0" Margin="3,3,3,1" RowSpan="2" />
<Border Name="mgrCellborder2" BorderBrush="#000000" BorderThickness="1" CornerRadius="5,5,0,0" Opacity="0" Margin="2,2,2,0" RowSpan="2" />
<Border Name="mgrCellborder1" BorderBrush="#FFFFFF" BorderThickness="1" CornerRadius="5,5,0,0" Opacity="0" Margin="1,1,1,0" RowSpan="2" />
...
What I can't figure out is how to target the elements in there, say, to make them invisible or to recreate my own. Is it possible to target named controls rather than just a type?
e.g.
<Style TargetType="{x:Type Grid x:Name mgrCellBorder1}" >
<Setter Property="Visibility" Value="Collapsed />
</Style>
How do you "get inside" a ControlTemplate definition like that for ColumnManagerCell to change its appearance?
