Question

我正在编写一个小型密钥应用程序，并且我使用列表框从代码中动态可视化列表。现在的问题是它需要在Windows 7上使用，并且我在该平台上有可视化的多个问题。

我的代码是：

<ListBox x:Name="listBoxSecrets" Margin="0,84,10,10" Background="{x:Null}"
             HorizontalContentAlignment="Stretch" BorderBrush="{x:Null}" >
<ListBox.ItemTemplate>
    <DataTemplate>
        <!--<Border BorderBrush="#FFF3560D" CornerRadius="3" BorderThickness="3" Margin="0,0,0,10">-->
        <Border BorderBrush="White" CornerRadius="10" BorderThickness="10" Margin="0,0,0,10">
            <Grid Background="White">
                <Grid.RowDefinitions>
                    <RowDefinition Height="Auto" />
                </Grid.RowDefinitions>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="Auto" />
                    <ColumnDefinition  Width="*" />
                    <ColumnDefinition  Width="30" />
                    <ColumnDefinition  Width="30" />
                </Grid.ColumnDefinitions>
                <StackPanel Uid="{Binding Path=ID}" Grid.Row="0" Grid.Column="0">
                    ...
                </StackPanel>


                <Button  ... Grid.Row="0" Grid.Column="2">
                    ...
                </Button>
                <Button  ... Grid.Row="0"  Grid.Column="3" >
                    ...
                </Button>
            </Grid>
        </Border>
    </DataTemplate>
</ListBox.ItemTemplate>

我尝试了以下样式无效：

    <Window.Resources>
    <Style x:Key="{x:Type ListBox}" TargetType="{x:Type ListBox}">
        <Setter Property="Focusable" Value="False" />
        <Setter Property="FocusVisualStyle" Value="{x:Null}" />
    </Style>
</Window.Resources>

这是选择的样子 - 我不希望它是可选择的。（我的按钮btw也有同样的问题 - 同样的解决方案适用吗？）

另外：如果你可以帮我弄清楚如何删除＆＃34;别名＆＃34;网格和它周围边界之间的界线..; - ;只有win 7 mahcine，而不是我的win 8机器。

Answer 1

为什么不在发生时删除选择？像这样：

private void listBoxSecrets_SelectionChanged(object sender, EventArgs e)
{
    listBoxSecrets.SelectedIndex = -1;
}

然后按照以下方式设置监听器：

<ListBox x:Name="listBoxSecrets" Margin="0,84,10,10" Background="{x:Null}"
         HorizontalContentAlignment="Stretch" BorderBrush="{x:Null}" SelectionChanged="listBoxSecrets_SelectionChanged" >

我想你要删除ListBoxItem的选择状态，如果没错，请使用下面的样式，在这个我已经注释掉了负责选择和鼠标悬停状态的触发器。您可以在ListBox的ItemContainerStyle中指定此样式，

  <Style x:Key="FocusVisual">
        <Setter Property="Control.Template">
            <Setter.Value>
                <ControlTemplate>
                    <Rectangle Margin="2" SnapsToDevicePixels="true" Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" StrokeThickness="1" StrokeDashArray="1 2"/>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
    <SolidColorBrush x:Key="Item.MouseOver.Background" Color="#1F26A0DA"/>
    <SolidColorBrush x:Key="Item.MouseOver.Border" Color="#a826A0Da"/>
    <SolidColorBrush x:Key="Item.SelectedInactive.Background" Color="#3DDADADA"/>
    <SolidColorBrush x:Key="Item.SelectedInactive.Border" Color="#FFDADADA"/>
    <SolidColorBrush x:Key="Item.SelectedActive.Background" Color="#3D26A0DA"/>
    <SolidColorBrush x:Key="Item.SelectedActive.Border" Color="#FF26A0DA"/>
    <Style x:Key="ListBoxItemStyle1" TargetType="{x:Type ListBoxItem}">
        <Setter Property="SnapsToDevicePixels" Value="True"/>
        <Setter Property="Padding" Value="4,1"/>
        <Setter Property="HorizontalContentAlignment" Value="{Binding HorizontalContentAlignment, RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}"/>

                                <Condition Property="IsSelected" Value="True"/>
                            </MultiTrigger.Conditions>
                            <Setter Property="Background" TargetName="Bd" Value="{StaticResource Item.SelectedInactive.Background}"/>
                            <Setter Property="BorderBrush" TargetName="Bd" Value="{StaticResource Item.SelectedInactive.Border}"/>

                        </Trigger>
