假设我有以下代码（您可以创建一个新的WPF项目并测试它，只需给默认的Grid名称MainGrid）：
namespace WPFTesting
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
ObservableCollection<Message> messages = new ObservableCollection<Message>();
public MainWindow()
{
InitializeComponent();
messages.Add(new Message(DateTime.Now, "This is a test."));
messages.Add(new Message(DateTime.Now, "This is a multi-line message.\nThis is a multi-line message."));
messages.Add(new Message(DateTime.Now, "This is a multi-line message.\nThis is a multi-line message."));
messages.Add(new Message(DateTime.Now, "This is a multi-line message.\nThis is a multi-line message."));
messages.Add(new Message(DateTime.Now, "This is a test."));
messages.Add(new Message(DateTime.Now, "This is a test."));
messages.Add(new Message(DateTime.Now, "This is a test."));
messages.Add(new Message(DateTime.Now, "This is a test."));
ListView listView = new ListView();
Style style = new Style();
style.TargetType = typeof(ListViewItem);
DataTrigger trigger = new DataTrigger();
trigger.Binding = new Binding("Text");
trigger.Value = "This is a test.";
trigger.Setters.Add(new Setter(ListViewItem.BackgroundProperty, Brushes.Pink));
style.Triggers.Add(trigger);
style.Setters.Add(new Setter(ListViewItem.HeightProperty, 20.0));
style.Setters.Add(new Setter(ListViewItem.MarginProperty, new Thickness(0)));
style.Setters.Add(new Setter(ListViewItem.BorderThicknessProperty, new Thickness(0)));
listView.ItemContainerStyle = style;
GridView gridView = new GridView();
listView.View = gridView;
GridViewColumn timeStampColumn = new GridViewColumn();
timeStampColumn.DisplayMemberBinding = new Binding("Date");
GridViewColumnHeader timeStampHeader = new GridViewColumnHeader();
timeStampHeader.Content = "Time";
timeStampColumn.Header = timeStampHeader;
gridView.Columns.Add(timeStampColumn);
GridViewColumn messageColumn = CreateGridViewColumn("Message", "Text");
gridView.Columns.Add(messageColumn);
Binding binding = new Binding();
binding.Source = messages;
listView.SetBinding(ItemsControl.ItemsSourceProperty, binding);
MainGrid.Children.Add(listView);
}
private static GridViewColumn CreateGridViewColumn(string header, string bindingPath)
{
GridViewColumn gridViewColumn = new GridViewColumn();
gridViewColumn.Header = new GridViewColumnHeader() { Content = header };
string xaml = @"
<DataTemplate xmlns=""http://schemas.microsoft.com/winfx/2006/xaml/presentation"" xmlns:x=""http://schemas.microsoft.com/winfx/2006/xaml"">
<StackPanel Orientation=""Horizontal"">
<TextBlock Text=""{Binding Text}"" MaxHeight=""20"">
<TextBlock.ToolTip>
<TextBlock Text=""{Binding Text}""/>
</TextBlock.ToolTip>
</TextBlock>
</StackPanel>
</DataTemplate>";
StringReader stringReader = new StringReader(xaml);
XmlReader xmlReader = XmlReader.Create(stringReader);
gridViewColumn.CellTemplate = XamlReader.Load(xmlReader) as DataTemplate;
return gridViewColumn;
}
public class Message
{
public Message(DateTime aDate, String aText)
{
Date = aDate;
Text = aText;
}
public DateTime Date { get; set; }
public String Text { get; set; }
}
}
}
请注意，在粉色线条之间，ListViewItems具有轻微的圆角。如何删除此效果？
此外，行选择并不是那么明显，因为我删除了边框粗细。如何使行选择更明显？我正在考虑反转背景颜色，但这可能不是一个好主意，或者可能添加一个具有一定透明度的画笔？我不完全确定如何做到这一点，有人可以告诉我吗？

您可以为Style创建新的ControlTemplate来覆盖ListViewItem。这是一项很多工作，因为它需要您重新定义所有VisualStates，Triggers等。
我已经包含了足够的代码来演示代码背后的过程，这将删除圆角边框。如果你想沿着这条路走下去，我会留给你添加VisualStates。
public MainWindow()
{
InitializeComponent();
messages.Add(new Message(DateTime.Now, "This is a test."));
messages.Add(new Message(DateTime.Now, "This is a multi-line message.\nThis is a multi-line message."));
messages.Add(new Message(DateTime.Now, "This is a multi-line message.\nThis is a multi-line message."));
messages.Add(new Message(DateTime.Now, "This is a multi-line message.\nThis is a multi-line message."));
messages.Add(new Message(DateTime.Now, "This is a test."));
messages.Add(new Message(DateTime.Now, "This is a test."));
messages.Add(new Message(DateTime.Now, "This is a test."));
messages.Add(new Message(DateTime.Now, "This is a test."));
ListView listView = new ListView();
CreateListViewItemStyle(listView);
GridView gridView = new GridView();
listView.View = gridView;
GridViewColumn timeStampColumn = new GridViewColumn();
timeStampColumn.DisplayMemberBinding = new Binding("Date");
GridViewColumnHeader timeStampHeader = new GridViewColumnHeader();
timeStampHeader.Content = "Time";
timeStampColumn.Header = timeStampHeader;
gridView.Columns.Add(timeStampColumn);
GridViewColumn messageColumn = CreateGridViewColumn("Message", "Text");
gridView.Columns.Add(messageColumn);
Binding binding = new Binding();
binding.Source = messages;
listView.SetBinding(ItemsControl.ItemsSourceProperty, binding);
MainGrid.Children.Add(listView);
}
private static void CreateListViewItemStyle(ListView listView)
{
string xaml = @"
<Style xmlns=""http://schemas.microsoft.com/winfx/2006/xaml/presentation"" xmlns:x=""http://schemas.microsoft.com/winfx/2006/xaml"" TargetType=""ListViewItem"">
<Setter Property=""Height"" Value=""20""/>
<Setter Property=""Template"">
<Setter.Value>
<ControlTemplate TargetType=""{x:Type ListViewItem}"">
<Border Background=""{TemplateBinding Background}""
CornerRadius=""0"">
<GridViewRowPresenter/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<DataTrigger Binding=""{Binding Text}"" Value=""This is a test."">
<Setter Property=""Background"" Value=""Pink""/>
</DataTrigger>
</Style.Triggers>
</Style>";
StringReader stringReader = new StringReader(xaml);
XmlReader xmlReader = XmlReader.Create(stringReader);
listView.ItemContainerStyle = XamlReader.Load(xmlReader) as Style;
}

尝试看下面的XAML编码。使用Datagrid代替ListView。
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Window.Resources>
<Style TargetType="{x:Type DataGridRow}">
<Style.Triggers>
<Trigger Property="IsMouseOver"
Value="True">
<Setter Property="Background"
Value="Red" />
<Setter Property="FontWeight"
Value="ExtraBold" />
<Setter Property="Height"
Value="20" />
</Trigger>
<DataTrigger Binding="{Binding Text}" Value="This is a test.">
<Setter Property="Background" Value="Pink" />
</DataTrigger>
</Style.Triggers>
</Style>
</Window.Resources>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid x:Name="MainGrid" />
<DataGrid Margin="10" Grid.Row="1" x:Name="MainGrid1"
AutoGenerateColumns="False"
AlternationCount="2"
FrozenColumnCount="2">
<DataGrid.Columns>
<DataGridTextColumn Binding="{Binding Date}"
Header="Time" Width="Auto" />
<DataGridTextColumn Binding="{Binding Text}"
Header="Message" Width="*" />
</DataGrid.Columns>
</DataGrid>
</Grid>
在MainWindow的构造函数结束时，添加以下最后一行
Binding binding = new Binding();
binding.Source = messages;
listView.SetBinding(ItemsControl.ItemsSourceProperty, binding);
MainGrid.Children.Add(listView);
MainGrid1.ItemsSource = messages;
您可能需要编写多项目以检查文本值并将鼠标悬停在其上，然后更改相应的背景颜色。

将样式直接应用于ListView时，它似乎可以正常工作。我相信您使用GridView作为ListView视图的项目强制使用圆角样式。
如果可能的话，我建议您考虑使用不同的控件集来显示您的项目。
