我正在使用WinUI CommunityToolkit DataGrid从this nuget包.下面是我数据网格定义：

<toolkit:DataGrid x:Name="dataGrid"
                  ItemsSource="{x:Bind ViewModel.Tests, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
                  MinHeight="500"
                  AreRowDetailsFrozen="False"
                  AreRowGroupHeadersFrozen="True"
                  AutoGenerateColumns="False"
                  CanUserSortColumns="True"
                  ColumnHeaderHeight="40"
                  FrozenColumnCount="0"
                  RowDetailsVisibilityMode="Collapsed"
                  RowGroupHeaderPropertyNameAlternative="Range">
    <toolkit:DataGrid.Columns>
        <toolkit:DataGridTemplateColumn Header="Records (count)" Tag="RecordsCount" Width="150">
            <toolkit:DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" Text="{Binding RecordsCount}"/>
                </DataTemplate>
            </toolkit:DataGridTemplateColumn.CellTemplate>
        </toolkit:DataGridTemplateColumn>
        <toolkit:DataGridTemplateColumn  Width="184">
            <toolkit:DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <StackPanel HorizontalAlignment="Right" Orientation="Horizontal">
                        <!-- Click event works but command doesn't getting executed -- >
                        <Button Width="40" Height="40" 
                                Command="{Binding ViewModel.DeleteTestCommand, ElementName=testPage}"
                                CommandParameter="{Binding Id}">
                        </Button>
                        <Button Width="40" Height="40"
                                Command="{Binding ViewModel.EditTestCommand, ElementName=testPage}"
                                CommandParameter="{Binding Id}">
                        </Button>
                    </StackPanel>
                </DataTemplate>
            </toolkit:DataGridTemplateColumn.CellTemplate>
        </toolkit:DataGridTemplateColumn>
    </toolkit:DataGrid.Columns>
</toolkit:DataGrid>

下面是我视图模型：

public partial class TestsPageViewModel : ObservableRecipient
{
    public IRelayCommand<int> EditTestCommand { get; }
    public IRelayCommand<int> DeleteTestCommand { get; }
    public TestsPageViewModel(ITestsQueryService testsQueryService, INavigationService navigationService)
    {
        EditTestCommand = new RelayCommand<int>(EditTest);
        DeleteTestCommand = new RelayCommand<int>(DeleteTest);
       
        Tests = new ObservableCollection<TestModel>(); //(Some tests here);
    }
    public void DeleteTest(int id)
    {
        //var test = Tests.First(P => P.Id == id);
    }
    public void EditTest(int id)
    {
        //var test = Tests.First(P => P.Id == id);
    }
    public ObservableCollection<TestModel> Tests 
    { 
        get => _tests;
        set => SetProperty(ref _tests, value); 
    }
}

TestModel包含：

• 公共整型ID { get;设置; }
• public int findDuplicate {set; }，...

正如我在Xaml中提到的，Click事件适用于按钮，但命令根本不起作用。
tnx任何帮助😊
