当数据网格中的鼠标位于行上时,是否可以更改celltemplate中的按钮可见性。例如,当MouseIsOver=True
可见性True
,MouseIsOver=False
可见性False
时。我该怎么用触发器? * *
的Xaml:
<Window x:Class="WpfApplication3.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">
<Grid>
<DataGrid ItemsSource="{Binding Items}" AutoGenerateColumns="False">
<DataGrid.Columns>
<DataGridTemplateColumn Header="Name">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<Label Content="{Binding .}"></Label>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
<DataGridTemplateColumn Header="Button">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<Button Visibility="Hidden">OK</Button>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
</DataGrid.Columns>
</DataGrid>
</Grid>
代码:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
namespace WpfApplication3
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
DataContext = new Data();
}
}
public class Struct
{
public string Name { get; set; }
}
public class Data
{
public List<string> Items { get; set; }
public Data()
{
Items = new List<string>();
Items.Add("First");
Items.Add("Second");
Items.Add("Third");
}
}
}

如果您的按钮被隐藏,则无法悬停。
在Visual Studio或Blend中,更改按钮的样式/模板以使ContentPresenter不可见:
在窗口中放置一个临时按钮,右键单击“编辑样式”/“编辑副本” 将样式命名为“InvisibleButtonStyle”。
在触发器部分,添加:
<Trigger Property="IsMouseOver" Value="false">
<Setter Property="Background" TargetName="border" Value="Transparent"/>
<Setter Property="BorderBrush" TargetName="border" Value="Transparent"/>
<Setter Property="Foreground" Value="Transparent"/>
</Trigger>
然后销毁临时按钮,并将样式应用于DataGrid按钮:
<Button Style="{StaticResource InvisibleButtonStyle}">OK</Button>
就是这样,快乐的编码
