        <EventSetter Event="PreviewMouseLeftButtonDown" Handler="ListViewItem_PreviewMouseLeftButtonDown" />
    </Style>
</Window.Resources>
<Grid>
    <TabControl x:Name="tabControl" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
        <TabItem Header="업무공지">
            <Grid Background="#FFE5E5E5">
                <Grid.RowDefinitions>
                    <RowDefinition Height="Auto" />
                    <RowDefinition Height="*" />
                    <RowDefinition Height="Auto" />

                            <GridViewColumn DisplayMemberBinding="{Binding Description}" Width="340" />
                        </GridView>
                    </ListView.View>
                </ListView>
            </Grid>

以上代码是我的xaml代码。

接下来，代码隐藏点击事件

---

private void ListViewItem_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
    var item = sender as ListViewItem;

    if (item != null && item.IsSelected)
    {
        MessageBox.Show(item.Content.ToString());
    }
}

我不想看到控件名称。

我想看到的是“案件已经结束”。成为。

如何获取我单击的列表视图单元格中的文本？

目前尚不清楚“案件已结束”文本的来源，但您可以尝试将 Content 转换为 Task 并访问其任何属性：

private void ListViewItem_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
    var item = sender as ListViewItem;
    if (item != null && item.IsSelected)
    {
        var task = item.Content as Copsys.Comm.Messenger.Task;
        if (task != null)
        {
            MessageBox.Show(task.Description);
        }
    }
}
