【问题描述】：
假设我有以下代码（您可以创建一个新的 WPF 项目并对其进行测试，只需将默认 Grid 命名为 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; }
}
}
}
注意粉色线之间，ListViewItems 有轻微的圆角。如何消除这种影响？
此外，行选择并不是那么明显，因为我删除了边框厚度。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？我不完全确定该怎么做，有人可以告诉我吗？
【问题讨论】：
-
一个无关紧要的问题：为什么要使用代码隐藏将样式应用于控件？这正是创建 XAML 的原因。
-
没问题。我使用的第三方控件需要我动态添加元素，所以我不能标记它们，否则，相信我，我会的！我的例子是最简单的情况；这是一个更大的解决方案的一部分。 :P
