列表框WPF项目背景颜色

Question

我想更改ListBoxItem的背景颜色

搜索后我决定使用它

<ListBox>
        <ListBox.Resources>
            <!-- Background of selected item when focussed -->
            <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}"
                             Color="Blue" />
            <!-- Background of selected item when not focussed -->
            <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}"
                             Color="Blue" />

        </ListBox.Resources>
        <TextBlock>fdfsdf1</TextBlock>
        <TextBlock>fdfsdf3</TextBlock>
        <TextBlock>fdfsdf5</TextBlock>
        <TextBlock>fdfsdf3</TextBlock>
        <TextBlock>fdfsdf4</TextBlock>
    </ListBox>

当一个listboxitem被聚焦时,背景是预期的蓝色,但是当所选的listboxitem失去焦点时,背景变为灰色.当失去焦点时,如何使背景保持蓝色？

Answer 1

如果你的意思是它的选择但不活跃的尝试 InactiveSelectionHighlightBrushKey

    <ListBox.Resources>
        <!-- Background of selected item when focussed -->
        <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}"
                         Color="Blue" />
        <!-- Background of selected item when not focussed -->
        <SolidColorBrush x:Key="{x:Static SystemColors.InactiveSelectionHighlightBrushKey}"
                         Color="Blue" />

    </ListBox.Resources>

试试这个

<ListBox>
        <ListBox.Resources>
            <Style TargetType="ListBoxItem">
                <Setter Property="Background" Value="Blue" />
            </Style>
        </ListBox.Resources>
        <TextBlock>fdfsdf1</TextBlock>
        <TextBlock>fdfsdf3</TextBlock>
        <TextBlock>fdfsdf5</TextBlock>
        <TextBlock>fdfsdf3</TextBlock>
        <TextBlock>fdfsdf4</TextBlock>
    </ListBox>
