利用WPF的ListView控件实现类似于Winform中DataGrid行背景色交替变换的效果，同时增加鼠标的悬停效果。
1.本文实现的效果如下：
2.所有的效果，我通过C#代码实现。代码如下：
using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Windows.Controls;using System.Windows;using System.Windows.Media;using System.ComponentModel;using System.Windows.Media.Animation;namespace BarCodeSystem{ public class ListViewItemStyleSelector:StyleSelector { private Dictionary> storyboards = new Dictionary>(); /// /// 下面的示例演示如何定义一个为行定义 Style 的 StyleSelector。 /// 此示例依据行索引定义 Background 颜色，为每行定义ListViewItem的动画板（Storyboard）。 ///ListView控件在初始化的时候，每初始化一行ListViewItem的时候都会进入该函数 /// /// /// /// public override Style SelectStyle(object item, DependencyObject container) { Style st = new Style(); st.TargetType=typeof(ListViewItem); Setter backGroundSetter = new Setter(); backGroundSetter.Property = ListViewItem.BackgroundProperty; ListView listview = ItemsControl.ItemsControlFromItemContainer(container) as ListView;//获得当前ListView int index = listview.ItemContainerGenerator.IndexFromContainer(container);//行索引 if (index % 2 == 0) { backGroundSetter.Value = Brushes.AliceBlue; } else { backGroundSetter.Value = Brushes.Transparent; } st.Setters.Add(backGroundSetter); //获得当前ListViewItem ListViewItem iteml = (ListViewItem)listview.ItemContainerGenerator.ContainerFromIndex(index); //故事板列表，用来存放1.鼠标进入故事板2.鼠标离开故事板 List sbl = new List(); //声明故事板 Storyboard storyboard = new Storyboard(); //1.鼠标进入故事板 //声明动画 DoubleAnimation fontEnterAnimation = new DoubleAnimation(); //动画的目标值 fontEnterAnimation.To = 16; //开始之前的等待时间，设置0.5s的等待时间是为了模拟“悬停时间” fontEnterAnimation.BeginTime = TimeSpan.FromSeconds(0.5); //动画持续时间 fontEnterAnimation.Duration = TimeSpan.FromSeconds(1); //动画缓动，可要可不要 fontEnterAnimation.EasingFunction = new ElasticEase() { EasingMode=EasingMode.EaseOut}; //绑定动画目标控件 Storyboard.SetTarget(fontEnterAnimation, iteml); //绑定动画目标属性 Storyboard.SetTargetProperty(fontEnterAnimation, new PropertyPath("FontSize")); //将动画板添加到故事板中 storyboard.Children.Add(fontEnterAnimation); sbl.Add(storyboard); //2.鼠标离开故事板 storyboard = new Storyboard(); DoubleAnimation fontLeaveAnimation = new DoubleAnimation(); fontLeaveAnimation.BeginTime = TimeSpan.FromSeconds(0); fontLeaveAnimation.Duration = TimeSpan.FromSeconds(0.5); Storyboard.SetTarget(fontLeaveAnimation, iteml); Storyboard.SetTargetProperty(fontLeaveAnimation, new PropertyPath("FontSize")); storyboard.Children.Add(fontLeaveAnimation); sbl.Add(storyboard); storyboards.Add(iteml, sbl); //绑定鼠标进入事件 iteml.MouseEnter += new System.Windows.Input.MouseEventHandler(iteml_MouseEnter); //绑定鼠标离开事件 iteml.MouseLeave += new System.Windows.Input.MouseEventHandler(iteml_MouseLeave); return st; } /// /// 鼠标进入事件 /// /// /// private void iteml_MouseEnter(object sender, RoutedEventArgs e) { ListViewItem item=(ListViewItem)sender; List storyboard = storyboards[item]; storyboard[0].Begin(); } private void iteml_MouseLeave(object sender, RoutedEventArgs e) { ListViewItem item = (ListViewItem)sender; List storyboard = storyboards[item]; storyboard[1].Begin(); } }}
3.Xaml文件中代码如下：
4.完成。
