我有两个ListView,每个列表都包含一些行。我想在选择行后调用函数。但是我遇到了一个问题,当选中行或点击该行中的按钮时,事件“GotFocus”会触发。当我使用<i:EventTrigger EventName="Selected">
时,表格中的行被选中时它不会触发。我需要怎么做?
Xaml:
<Grid>
<ListView Width="200" Height="200" ItemsSource="{Binding Items}" HorizontalAlignment="Left">
<ListView.ItemTemplate>
<DataTemplate>
<Button Content="{Binding .}">
</Button>
</DataTemplate>
</ListView.ItemTemplate>
<i:Interaction.Triggers>
<i:EventTrigger EventName="GotFocus">
<i:InvokeCommandAction Command="{Binding DataContext.TestCommand, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type vm:MainWindow }}}"></i:InvokeCommandAction>
</i:EventTrigger>
</i:Interaction.Triggers>
</ListView>
<ListBox Width="200" Height="200" ItemsSource="{Binding Items}" HorizontalAlignment="Right">
<ListBox.ItemTemplate>
<DataTemplate>
<Button Content="{Binding .}">
</Button>
</DataTemplate>
</ListBox.ItemTemplate>
<i:Interaction.Triggers>
<i:EventTrigger EventName="GotFocus">
<i:InvokeCommandAction Command="{Binding DataContext.TestTestCommand, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type vm:MainWindow }}}"></i:InvokeCommandAction>
</i:EventTrigger>
</i:Interaction.Triggers>
</ListBox>
</Grid>
代码:
namespace WpfApplication129
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
DataContext = new Data();
InitializeComponent();
}
}
public class Data
{
public ICommand TestCommand { get; set; }
public ICommand TestTestCommand { get; set; }
public List<string> Items { get; set; }
public Data()
{
TestCommand = new RelayCommand(() => Test());
TestTestCommand = new RelayCommand(() => TestTest());
Items = new List<string>();
Items.Add("first");
Items.Add("Second");
Items.Add("Third");
}
public void Test()
{
MessageBox.Show("Running");
}
public void TestTest()
{
MessageBox.Show("TestRunning");
}
}
}
