获取有关CurrentCellChanged

Question

WPF的DataGrid单元格内容我有一个WPFDataGrid。我想用户编辑后得到cell值。该DataGrid已填充了数据。用户可以编辑以前的数据。为了保存我想要的数据cell来自event handler的数据

给我一个简单的代码来做到这一点。推荐一个event handler。

Answer 1

只要用户编辑了单元格，就可以使用CellEditEnding事件来获取通知。

这个简单的程序说明了它：

XAML

<Window x:Class="WpfApplication1.MainWindow" 
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
     xmlns:local="clr-namespace:WpfApplication1" 
     Title="MainWindow" Height="500" Width="500"> 
    <Grid> 
     <DataGrid x:Name="grid" CellEditEnding="cellEditEnding" /> 
    </Grid> 
</Window>

public partial class MainWindow : Window 
{ 
    public class MyClass 
    { 
     public string Prop1 { get; set; } 
     public string Prop2 { get; set; } 
     public string Prop3 { get; set; } 
    } 

    public MainWindow() 
    { 
     InitializeComponent(); 

     var objects = new[] 
     { 
      new MyClass { Prop1 = "Object1", Prop2 = "Test1", Prop3 = "Hello" }, 
      new MyClass { Prop1 = "Object2", Prop2 = "Test2", Prop3 = "Goodbye" }, 
      new MyClass { Prop1 = "Object3", Prop2 = "Test3", Prop3 = "Welcome" } 
     }; 

     grid.ItemsSource = objects; 
    } 

    private void cellEditEnding(object sender, DataGridCellEditEndingEventArgs e) 
    { 
     //Only handles cases where the cell contains a TextBox 
     var editedTextbox = e.EditingElement as TextBox; 

     if (editedTextbox != null) 
      MessageBox.Show("Value after edit: " + editedTextbox.Text); 
    } 
}
