Question

我想在选中后更改列表框背景颜色我试过这个

<ListBox.ItemContainerStyle>
                <Style TargetType="ListBoxItem">
                    <Style.Triggers>
                        <Trigger Property="IsSelected" Value="True" >
                            <Setter Property="FontWeight" Value="Bold" />
                            <Setter Property="Background" Value="Red" />
                        </Trigger>
                    </Style.Triggers>
                    <Style.Resources>
                        <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent" />
                        <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Transparent" />
                    </Style.Resources>
                </Style>
            </ListBox.ItemContainerStyle>

但它没有用。有人能帮帮我吗？

我认为你只是在错误的地方。试试这个。

<ListBox.ItemContainerStyle>
            <Style TargetType="ListBoxItem">
                <Style.Triggers>
                    <Trigger Property="IsSelected" Value="True" >
                        <Setter Property="FontWeight" Value="Bold" />
                        <Setter Property="Background" Value="Red" />
                    </Trigger>
                </Style.Triggers>
            </Style>
        </ListBox.ItemContainerStyle>
        <ListBox.Resources>
            <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent" />
            <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Transparent" />
        </ListBox.Resources>
