样式触发器的列表视图子项

我有一个ListView
,它是数据绑定到基于某些属性的项目行颜色代码。
我想重写一个特定的单元格,以根据不同的属性更改其颜色。
ListView
....
<Grid>
<ListView x:Name="dbItems" ItemsSource="{Binding itemList}" ScrollViewer.HorizontalScrollBarVisibility="Auto" ScrollViewer.VerticalScrollBarVisibility="Auto">
<ListView.Resources>
<Style TargetType="{x:Type ListViewItem}">
<Setter Property="Background" Value="{Binding connectionStatus, UpdateSourceTrigger=PropertyChanged, Converter={StaticResource converter}}" />
</Style>
<!--<Style TargetType="{x:Type ListViewItem.}">
<Setter Property="Background" Value="{Binding badSubItem, UpdateSourceTrigger=PropertyChanged, Converter={StaticResource cellConverter}}" />
</Style>-->
</ListView.Resources>
<ListView.View>
<GridView>
<GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}" />
<GridViewColumn Header="DESCRIPTION" DisplayMemberBinding="{Binding description}" />
<GridViewColumn Header="RESOURCE" DisplayMemberBinding="{Binding resource}" />
<GridViewColumn Header="SubItem" DisplayMemberBinding="{Binding subItemFound}" />
<GridViewColumn Header="Count" DisplayMemberBinding="{Binding count}"/>
</GridView>
</ListView.View>
</ListView>
</Grid>
每行的初始颜色编码由Converter
处理。
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
switch ((Interfaces.Enum.Status)value)
{
case Interfaces.Enum.Status.Unknown:
return Brushes.LightGray;
case Interfaces.Enum.Status.Offline:
return Brushes.Red;
case Interfaces.Enum.Status.Online:
return Brushes.Green;
case Interfaces.Enum.Status.OnlineButNotInitialized:
return Brushes.OrangeRed;
default:
return Brushes.LightGray;
}
}
细胞的颜色变化,我希望使用另一个Converter
…
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
if (!(bool)value)
return Brushes.LightGreen;
return Brushes.Yellow;
}
问题是在注释出来的风格标签(第二个ListViewItem
风格),因为这需要只适用于特定的单元格(子项- bool),但我似乎找不到正确的绑定类型。有没有人能在这方面帮助我,或者给我指出正确的方向来完成这件事……
将IsSomething
替换为要绑定到
<Style x:Key="MyDataGridCell" TargetType="DataGridCell" BasedOn="{StaticResource {x:Type DataGridCell}}">
<Setter Property="Background" Value="White"/>
<Setter Property="Foreground" Value="Black"/>
<Style.Triggers>
<Trigger Property="{Binding IsSomething}" Value="True">
<Setter Property="Background" Value="Red"/>
<Setter Property="Foreground" Value="White"/>
</Trigger>
</Style.Triggers>
</Style>
<DataGrid CellStyle="{StaticResource MyDataGridCell}" />
