Question

我是WPF的新手。我曾经在Winforms工作。

在Winforms中我有DataGridView，允许我在需要单元格值时进行更改。

只需使用：

dataGridView[columnIndex, rowIndex].Value = "New Value";

有效。

如何使用WPF中的DataGrid完成此操作？我一直在寻找流动的东西，并且可以找到一种简单的方法来做到这一点。

谢谢

好的，处理DataGrid的最简单方法是绑定到ItemSource。

下面的示例显示了如何绑定列表以及更改如何更新DataGrid。

public partial class MainWindow : Window
{
    private ObservableCollection<ConnectionItem> _connectionitems = new ObservableCollection<ConnectionItem>();

    public MainWindow()
    {
        InitializeComponent();
        ConnectionItems.Add(new ConnectionItem { Name = "Item1", Ping = "150ms" });
        ConnectionItems.Add(new ConnectionItem { Name = "Item2", Ping = "122ms" });
    }

    public ObservableCollection<ConnectionItem> ConnectionItems
    {
        get { return _connectionitems; }
        set { _connectionitems = value; }
    }

    private void button1_Click(object sender, RoutedEventArgs e)
    {
        // to change a value jus find the item you want in the list and change it
        // because your ConnectionItem class implements INotifyPropertyChanged
        // ite will automaticly update the dataGrid

        // Example
        ConnectionItems[0].Ping = "new ping :)";
    }
}

public class ConnectionItem : INotifyPropertyChanged
{
    private string _name;
    private string _ping;

    public string Name
    {
        get { return _name; }
        set { _name = value; NotifyPropertyChanged("Name"); }
    }

    public string Ping
    {
        get { return _ping; }
        set { _ping = value; NotifyPropertyChanged("Ping"); }
    }

    public event PropertyChangedEventHandler PropertyChanged;
    /// <summary>
    /// Notifies the property changed.
    /// </summary>
    /// <param name="property">The info.</param>
    public void NotifyPropertyChanged(string property)
    {
        if (PropertyChanged != null)
        {
            PropertyChanged(this, new PropertyChangedEventArgs(property));
        }
    }
}

的Xaml：

<Window x:Class="WpfApplication4.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:WpfApplication4"
        xmlns:properties="clr-namespace:WpfApplication4.Properties"
        Title="MainWindow" Height="300" Width="400" Name="UI" >
    <Grid>
        <DataGrid Name="dataGridView" ItemsSource="{Binding ElementName=UI,Path=ConnectionItems}" Margin="0,0,0,40" />
        <Button Content="Change" Height="23" HorizontalAlignment="Left" Margin="5,0,0,12" Name="button1" VerticalAlignment="Bottom" Width="75" Click="button1_Click" />
    </Grid>
</Window>

我添加了一个按钮，用于显示当您更改列表中的内容时数据如何更新，ConnectionItem类是您存储数据网格的所有信息的地方。

希望这有帮助
