从WPF GridViewColumn通过按钮获取内容

Question

我在ListView中的GridView中有一个Button。点击按钮时，我想从该按钮的网格视图的相应行中获取文本。任何人都可以帮我用这个代码吗？

我的XAML是：

<ListView Name="resultList" ItemsSource="{Binding}" DockPanel.Dock="Top"> 
<ListView.View> 
    <GridView AllowsColumnReorder="true" ColumnHeaderToolTip="Test Results Summary"> 
    <GridViewColumn DisplayMemberBinding= "{Binding Date}" Header="Date" Width="Auto"/> 
    <GridViewColumn DisplayMemberBinding= "{Binding Status}" Header="Status" Width="Auto"/> 
    <GridViewColumn Header="" Width="Auto"> 
     <GridViewColumn.CellTemplate> 
     <DataTemplate > 
     <Button x:Name="btnRemoveTest" Click="_viewResult" Content="View" Height="20" Width="100"/> 
     </DataTemplate> 
     </GridViewColumn.CellTemplate> 
    </GridViewColumn> 
    </GridView> 
    </ListView.View> 
    </ListView> 

我可以在这里做：

private void _viewResult(object sender, RoutedEventArgs e) 
{ 
} 

Answer 1

使用ButtonDataContext，如下图所示。请注意，在此示例代码中，我正在使用Customer。

private void _viewResult(object sender, RoutedEventArgs e) 
{ 
    Button button = sender as Button; 
    Customer cust = button.DataContext as Customer; 

    string sDate = cust.Date; 
    string sStatus = cust.Status; 
} 

以下是完整的工作代码。

MainWindow.xaml.cs

using System.Collections.Generic; 
using System.Collections.ObjectModel; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 
using System.Windows; 
using System.Windows.Controls;

namespace ListViewButtonClick 
{ 
    /// <summary> 
    /// Interaction logic for MainWindow.xaml 
    /// </summary> 
    public partial class MainWindow : Window 
    { 
     public MainWindow() 
     { 
      InitializeComponent(); 

      resultList.ItemsSource = new Customers(); 
     } 
     private void _viewResult(object sender, RoutedEventArgs e) 
     { 
      Button button = sender as Button; 
      Customer cust = button.DataContext as Customer; 
      string sDate = cust.Date; 
      string sStatus = cust.Status; 
     } 
    } 
    public class Customer 
    { 
     public String Date { get; set; } 
     public String Status { get; set; } 

     public Customer(String Date, String Status) 
     { 
      this.Date = Date; 
      this.Status = Status; 
     } 
    } 
    public class Customers : ObservableCollection<Customer> 
    { 
     public Customers() 
     { 
      Add(new Customer("11/23/2015", "in progress")); 
      Add(new Customer("11/24/2015", "Done")); 
      Add(new Customer("11/22/2015", "Not yet done")); 
     } 
    } 
}
