Wpf datagrid 输入键移动下一行

在WPF应用程序中，DataGrid是一个非常常用的控件，用于以表格形式展示和编辑数据。在使用DataGrid时，经常会遇到需要通过键盘输入来移动到下一行的需求。本文将介绍如何通过自然语言生成一篇文章，并提供相应的案例代码来实现这个功能。

xaml
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="450" Width="800">
    
        
            
                
                
            
        
    

csharp
public partial class MainWindow : Window
{
    private ObservableCollection people;
    public MainWindow()
    {
        InitializeComponent();
        // 初始化数据
        people = new ObservableCollection
        {
            new Person { Name = "Alice", Age = 25 },
            new Person { Name = "Bob", Age = 30 },
            new Person { Name = "Charlie", Age = 35 }
        };
        dataGrid.ItemsSource = people;
        // 订阅PreviewKeyDown事件
        dataGrid.PreviewKeyDown += DataGrid_PreviewKeyDown;
    }
    private void DataGrid_PreviewKeyDown(object sender, KeyEventArgs e)
    {
        if (e.Key == Key.Enter)
        {
            e.Handled = true;
            var dataGrid = (DataGrid)sender;
            var currentCell = dataGrid.CurrentCell;
            var columnIndex = currentCell.Column.DisplayIndex;
            var rowIndex = dataGrid.Items.IndexOf(currentCell.Item);
            // 移动焦点到下一行的相同列
            if (rowIndex < dataGrid.Items.Count - 1)
            {
                var nextCell = new DataGridCellInfo(dataGrid.Items[rowIndex + 1], dataGrid.Columns[columnIndex]);
                dataGrid.CurrentCell = nextCell;
                dataGrid.SelectedItem = nextCell.Item;
                dataGrid.ScrollIntoView(nextCell.Item);
            }
        }
    }
}
