显示选定列表项内的按钮

本文关键字：按钮 列表 显示 | 更新日期: 2023-09-27 17:51:10

我正在使用WPF应用程序来管理我们主要软件的版本。这个应用程序有一个ListBox，我将ListBox.DataTemplate设置为每个ListBoxItem都有一个Label和2个Buttons。

以下代码显示了我的ListBox代码: 
<ListBox Grid.Row="0" SelectedItem="{Binding Path=SelectedVersion}" ItemsSource="{Binding Path=PatchList, Mode=TwoWay}" d:DataContext="{d:DesignInstance {x:Type ViewModels:MainWindowViewModel}}"
                 SelectionMode="Single" IsSynchronizedWithCurrentItem="True" Margin="1" ScrollViewer.HorizontalScrollBarVisibility="Disabled" SelectedIndex="0">
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <Grid HorizontalAlignment="Stretch">
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width="*" />
                            <ColumnDefinition Width="Auto" />
                            <ColumnDefinition Width="Auto" />
                        </Grid.ColumnDefinitions>
                        <Label Grid.Column="0" Content="{Binding Path=VersionNumber}" HorizontalAlignment="Left" Foreground="#FFFFFF" FontSize="19" />
                        <Button Grid.Column="1" Width="25" Height="25" Template="{StaticResource OnMouseOverListBoxitem}" ToolTip="Release" Command="{Binding Path=DataContext.ReleaseVersionCommand, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ListBox}}}" HorizontalAlignment="Right" d:DataContext="{d:DesignInstance {x:Type ViewModels:MainWindowViewModel}}" CommandParameter="{Binding}">
                            <ContentControl Template="{StaticResource Release}" />
                        </Button>
                        <Button Grid.Column="2" Width="25" Height="25" Template="{StaticResource OnMouseOverListBoxitem}" ToolTip="Trash" Command="{Binding Path=DataContext.DeleteVersionCommand, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ListBox}}}" HorizontalAlignment="Right" d:DataContext="{d:DesignInstance {x:Type ViewModels:MainWindowViewModel}}" CommandParameter="{Binding}">
                            <ContentControl Template="{StaticResource Trash}" />
                        </Button>
                    </Grid>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>

问题是我想为Selected ListBoxItem显示标签和按钮仅。

顺便说一下，我使用bindings，如果你看到一些不同的代码，那是因为我也使用MahApp.Metro为windows8风格。

有什么建议吗?

谢谢。

试试这个。

  <Window.Resources>
        <BooleanToVisibilityConverter x:Key="BooleanToVisibilityConverter1" />
    </Window.Resources>
    <Grid>
        <ListBox ItemsSource="{Binding Fnts}" Grid.Row="0" SelectedItem="{Binding Path=SelectedVersion}" 
                 SelectionMode="Single" IsSynchronizedWithCurrentItem="True" Margin="1" ScrollViewer.HorizontalScrollBarVisibility="Disabled" SelectedIndex="0">
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <StackPanel Orientation="Horizontal">
                        <Label Content="{Binding}" />
                        <Button Content=" X " Visibility="{Binding RelativeSource={RelativeSource AncestorType={x:Type ListBoxItem}}, Path=IsSelected, Converter={StaticResource BooleanToVisibilityConverter1}}" />
                    </StackPanel>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>
    </Grid>
