I'm attempting to bind the Visibility property of a TextBlock
that's held within the ItemTemplate for a ListView to the IsSelected property of the TextBlock's parent ListViewItem.
With this markup, the TextBlock is always visible.
<ListView x:Name="ItemListView" ItemsSource="{Binding Path=Accounts}" Margin="60,0,0,10" Grid.Row="1" Grid.Column="0">
<ListView.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="100">
</ColumnDefinition>
<ColumnDefinition Width="*"></ColumnDefinition>
<ColumnDefinition Width="200"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Image Width="100" Height="100" Grid.Column="0"></Image>
<StackPanel Grid.Column="1">
<TextBlock Text="{Binding Path=Account.Name}"
FontSize="24" Margin="5,0,0,0" TextWrapping="Wrap" />
</StackPanel>
<TextBlock Grid.Column="3" VerticalAlignment="Bottom"
Visibility="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path=IsSelected, Converter={StaticResource boolConverter}, Mode=OneWay}">
Show More Details...
</TextBlock>
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
Notes:
1. In case it makes any difference, this is WinRT; a Metro app written in C#.
2. boolConverter
is a fairly standard converter appears to work correctly.
Use Mode=FindAncestor
:
<TextBlock Grid.Column="3" VerticalAlignment="Bottom"
Visibility="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=ListViewItem}, Path=IsSelected, Converter={StaticResource boolConverter}, Mode=OneWay}">
I think that in this case you will have to use ElementName=ItemListView
