C# 在WPF中设置listview ItemContainerStyle

我有一个

列表视图

，其中的行颜色不同：

<Grid>
    <Grid.Resources>
        <Style x:Key="RowColorStyle" TargetType="ListViewItem">
            <Setter Property="IsSelected" Value="{Binding IsSelected}"/>
            <Style.Triggers>
                <Trigger Property="ItemsControl.AlternationIndex"  Value="0">
                    <Setter Property="Background" Value="LightBlue" />
                </Trigger>
                <Trigger Property="ItemsControl.AlternationIndex"  Value="1">
                    <Setter Property="Background" Value="LightGray" />
                </Trigger>
                <Trigger Property="IsSelected" Value="True">
                    <Setter Property="Background" Value="Orange"/>
                </Trigger>
            </Style.Triggers>
        </Style>
    </Grid.Resources>

    <ListView ItemContainerStyle="{StaticResource alternatingStyle}" AlternationCount="2">
    </ListView>

</Grid>

---

现在的问题是listview多次定义

ItemContainerStyle

body，因此我试图移动

ItemContainerStyle=“{StaticResource alternatingStyle}”

在刚刚实现的上一个定义的

ItemContainerStyle

部分中，但我不知道如何执行。

我不确定您要问什么，但您可以使用

BasedOn

属性将

样式

建立在另一个样式的基础上：

<ListView AlternationCount="2">
    <ListView.ItemContainerStyle>
        <Style TargetType="ListViewItem" BasedOn="{StaticResource alternatingStyle}">
            <Setter Property="IsSelected" Value="{Binding IsSelected}"/>
            <EventSetter Event="PreviewMouseLeftButtonDown" Handler="lvi_MouseDown" />
            <EventSetter Event="PreviewMouseMove"  Handler="lvi_MouseMove" />
        </Style>
    </ListView.ItemContainerStyle>
</ListView>

---

最后，我通过以下操作解决了这个问题：

<Grid>
    <Grid.Resources>
        <Style x:Key="alternatingStyle" TargetType="ListViewItem">
            <Style.Setters>
                <Setter Property="IsSelected" Value="{Binding IsSelected}"/>
                <EventSetter Event="PreviewMouseLeftButtonDown" Handler="lvi_MouseDown" />
                <EventSetter Event="PreviewMouseMove"  Handler="lvi_MouseMove" />
            </Style.Setters>
            <Style.Triggers>
                <Trigger Property="ItemsControl.AlternationIndex"  Value="0">
                    <Setter Property="Background" Value="LightBlue" />
                </Trigger>
                <Trigger Property="ItemsControl.AlternationIndex"  Value="1">
                    <Setter Property="Background" Value="LightGray" />
                </Trigger>
                <Trigger Property="IsSelected" Value="True">
                    <Setter Property="Background" Value="Orange"/>
                </Trigger>
            </Style.Triggers>
        </Style>
    </Grid.Resources>

    <ListView ItemContainerStyle="{StaticResource alternatingStyle}"
                      AlternationCount="2">
    </ListView>
</Grid>

@mm8解决方案也可以使用BasedOn。

我更喜欢您的解决方案，因为您的解决方案将行交替颜色与其他事件设置器分开。

<Grid>
    <Grid.Resources>
        <Style x:Key="alternatingStyle" TargetType="ListViewItem">
            <Style.Setters>
                <Setter Property="IsSelected" Value="{Binding IsSelected}"/>
                <EventSetter Event="PreviewMouseLeftButtonDown" Handler="lvi_MouseDown" />
                <EventSetter Event="PreviewMouseMove"  Handler="lvi_MouseMove" />
            </Style.Setters>
            <Style.Triggers>
                <Trigger Property="ItemsControl.AlternationIndex"  Value="0">
                    <Setter Property="Background" Value="LightBlue" />
                </Trigger>
                <Trigger Property="ItemsControl.AlternationIndex"  Value="1">
                    <Setter Property="Background" Value="LightGray" />
                </Trigger>
                <Trigger Property="IsSelected" Value="True">
                    <Setter Property="Background" Value="Orange"/>
                </Trigger>
            </Style.Triggers>
        </Style>
    </Grid.Resources>

    <ListView ItemContainerStyle="{StaticResource alternatingStyle}"
                      AlternationCount="2">
    </ListView>
</Grid>
