【问题描述】：

如何为 uwp/winui 选择 datagrid 中的所有行？类似于 dataGrid.SelectAl();来自 WPF。

我在 uwp/winUI 中没有找到任何关于此的内容

【问题讨论】：

UWP 或 WinUI 中目前没有 datagrid 控件。您是在谈论来自社区工具包或某些第三方库的数据网格控件吗？

【解决方案1】：

您可以通过按控制钥匙和一个钥匙。

主窗口.xaml

<StackPanel>
    <Button
        Click="SelectAllButton_Click"
        Content="SelectAll" />
    <controls:DataGrid
        x:Name="DataGridControl"
        ItemsSource="{x:Bind Items, Mode=OneWay}"
        SelectionMode="Extended" />
</StackPanel>

主窗口.xaml.cs

public sealed partial class MainWindow : Window
{
    public MainWindow()
    {
        this.InitializeComponent();

        Items.Add(new Item() { Id = 0, Title = "A" });
        Items.Add(new Item() { Id = 1, Title = "B" });
        Items.Add(new Item() { Id = 2, Title = "C" });
    }

    public ObservableCollection<Item> Items { get; set; } = new();

    private void SelectAllButton_Click(object sender, RoutedEventArgs e)
    {
        this.DataGridControl.Focus(FocusState.Programmatic);

        var keys = new[]
        {
            new InjectedInputKeyboardInfo()
            {
                VirtualKey = (ushort)(VirtualKey.Control),
                KeyOptions = InjectedInputKeyOptions.None,
            },
            new InjectedInputKeyboardInfo()
            {
                VirtualKey = (ushort)(VirtualKey.A),
                KeyOptions = InjectedInputKeyOptions.None,
            },
        };

        InputInjector inputInjector = InputInjector.TryCreate();

        // Press the keys.
        inputInjector.InjectKeyboardInput(keys);

        foreach (InjectedInputKeyboardInfo key in keys)
        {
            key.KeyOptions = InjectedInputKeyOptions.KeyUp;
        }

        // Release the keys.
        inputInjector.InjectKeyboardInput(keys);
    }
}

【解决方案2】：

在 inputInjector.InjectKeyboardInput(keys) 中返回错误；

System.ArgumentException：“值不在预期范围内。”

【解决方案3】：

问题出现在数组中，由于某种原因，它不起作用，我通过单独发送密钥来解决它

谢谢，@Adrew！

this.dataGrid.Focus(FocusState.Programmatic);

        var inputInjector = InputInjector.TryCreate();
        // Press the keys.
        inputInjector.InjectKeyboardInput(new[] { new InjectedInputKeyboardInfo
        {
            VirtualKey = (ushort)VirtualKey.Control,
            KeyOptions = InjectedInputKeyOptions.None
        }});

        inputInjector.InjectKeyboardInput(new[] { new InjectedInputKeyboardInfo
        {
            VirtualKey = (ushort)VirtualKey.A,
            KeyOptions = InjectedInputKeyOptions.None
        }});

        // Release the keys.
        inputInjector.InjectKeyboardInput(new[] { new InjectedInputKeyboardInfo
        {
            VirtualKey = (ushort)VirtualKey.Control,
            KeyOptions = InjectedInputKeyOptions.KeyUp
        }});

        inputInjector.InjectKeyboardInput(new[] { new InjectedInputKeyboardInfo
        {
            VirtualKey = (ushort)VirtualKey.A,
            KeyOptions = InjectedInputKeyOptions.KeyUp
        }});
