将Xceed DataGridControl与Caliburn Micro绑定

Question

我想将Xceed DataGridControl与Caliburn Micro绑定。什么是设置绑定的最佳方式，我想在我的视图模型中使用没有ICommands的Caliburn样式方法。在输入密钥或双击网格中，它应该调用方法OpenContract(Contract c)。

查看：

<xcdg:DataGridControl ItemsSource="{Binding Contracts}" AutoCreateColumns="False"> 
    <xcdg:DataGridControl.InputBindings> 
     <KeyBinding Key="Enter" Command="{Binding Path=OpenContractCommand}" CommandParameter="{Binding ElementName=DataGrid, Path=SelectedItems}"/> 
     <MouseBinding MouseAction="LeftDoubleClick" Command="{Binding Path=OpenContractCommand}" CommandParameter="{Binding ElementName=DataGrid, Path=SelectedItems}"/> 
    </xcdg:DataGridControl.InputBindings> 
    <xcdg:DataGridControl.View> 
     <xcdg:TableView AllowColumnChooser="True" ShowFixedColumnSplitter="False" AllowRowResize="False" ShowRowSelectorPane="False" UseDefaultHeadersFooters="False" ColumnStretchMode="Last"> 
      <xcdg:TableView.FixedHeaders> 
       <DataTemplate> 
        <xcdg:ColumnManagerRow AllowColumnReorder="True" AllowSort="True" AllowColumnResize="True" AllowAutoFilter="False" /> 
       </DataTemplate> 
      </xcdg:TableView.FixedHeaders> 
     </xcdg:TableView> 
    </xcdg:DataGridControl.View> 
    <xcdg:DataGridControl.Columns> 
     <xcdg:Column FieldName="Name" Title="Name"></xcdg:Column> 
     <xcdg:Column FieldName="CustomerName" Title="Customer"></xcdg:Column> 
    </xcdg:DataGridControl.Columns> 
</xcdg:DataGridControl> 

视图模型：

public class ContractViewModel : Screen 
{ 
    public BindableCollection<Contract> Contracts { get; private set; } 
    private ContractRepository _repository; 

    public ContractViewModel(ContractRepository repository) 
    { 
     _repository = repository 
    } 

    public async void OnViewLoaded() 
    { 
     Contracts.Clear(); 
     Contracts.AddRange(_repository.GetAll()); 
    } 

    public IEnumerable<IResult> OpenContract(Contract contract) 
    { 
     yield return; 
    } 
}

原来可以用卡利(see this discussion)进行绑定：

<xcdg:DataGridControl ItemsSource="{Binding Contracts}" AutoCreateColumns="False"> 
    <xcdg:DataGridControl.Resources> 
     <Style TargetType="{x:Type xcdg:DataCell}"> 
      <Setter Property="cal:Message.Attach" Value="[Event PreviewMouseDoubleClick] = [Action OpenContract($this)]" /> 
     </Style> 
    </xcdg:DataGridControl.Resources> 
    <xcdg:DataGridControl.View> 
     <xcdg:TableView AllowColumnChooser="True" ShowFixedColumnSplitter="False" AllowRowResize="False" ShowRowSelectorPane="False" UseDefaultHeadersFooters="False" ColumnStretchMode="Last"> 
      <xcdg:TableView.FixedHeaders> 
       <DataTemplate> 
        <xcdg:ColumnManagerRow AllowColumnReorder="True" AllowSort="True" AllowColumnResize="True" AllowAutoFilter="False" /> 
       </DataTemplate> 
      </xcdg:TableView.FixedHeaders> 
     </xcdg:TableView> 
    </xcdg:DataGridControl.View> 
    <xcdg:DataGridControl.Columns> 
     <xcdg:Column FieldName="Name" Title="Name"></xcdg:Column> 
     <xcdg:Column FieldName="CustomerName" Title="Customer"></xcdg:Column> 
    </xcdg:DataGridControl.Columns> 
</xcdg:DataGridControl>
