XamPropertyGrid自定义编辑器（绑定）不起作用(XamPropertyGrid Custom Editor (Binding) not working)

 我在C＃WPF中使用Infragistics的“XamPropertyGrid”，我创建了两个类如下： 
 
public class ClassA
{
    public ClassB B { get; set; }
}

public class ClassB
{
    public bool C { get; set; }
}
 
 目标是为PropertyGrid创建一个自定义编辑器，其中包含一个Checkbox控件并设置ClassA实例的Property BC 
 
 这是我的xaml代码： 
 
<ig:XamPropertyGrid x:Name="pGrid">
        <ig:XamPropertyGrid.EditorDefinitions>
            <ig:PropertyGridEditorDefinition>
                <ig:PropertyGridEditorDefinition.TargetProperties>
                    <system:String>B</system:String>
                </ig:PropertyGridEditorDefinition.TargetProperties>
                <ig:PropertyGridEditorDefinition.EditTemplate>
                    <DataTemplate>
                        <CheckBox Content="XYC" IsChecked="{Binding Value.C}"></CheckBox>
                    </DataTemplate>
                </ig:PropertyGridEditorDefinition.EditTemplate>
            </ig:PropertyGridEditorDefinition>
        </ig:XamPropertyGrid.EditorDefinitions>
    </ig:XamPropertyGrid>
 
 首先，我为PropertyGrid设置所选对象，如下所示： 
 
public MainWindow()
    {
        InitializeComponent();

        ClassA a = new ClassA();
        a.B = new ClassB();

        pGrid.SelectedObject = a;

    }
 
 但是当我检查Checkbox时，Property C不会改变。 至于我调试了编辑器DataTemplate中的Value属性为null。 （我在Binding中放了一个转换器来检查它。） 
 
 先谢谢你。 

I am using Infragistics' "XamPropertyGrid" in C# WPF, I have created two classes as follow:
 
public class ClassA
{
    public ClassB B { get; set; }
}

public class ClassB
{
    public bool C { get; set; }
}
 
The Goal is to create a Custom Editor for PropertyGrid that contains a Checkbox Control and sets Property B.C of an instance of ClassA
 
Here is my xaml code:
 
<ig:XamPropertyGrid x:Name="pGrid">
        <ig:XamPropertyGrid.EditorDefinitions>
            <ig:PropertyGridEditorDefinition>
                <ig:PropertyGridEditorDefinition.TargetProperties>
                    <system:String>B</system:String>
                </ig:PropertyGridEditorDefinition.TargetProperties>
                <ig:PropertyGridEditorDefinition.EditTemplate>
                    <DataTemplate>
                        <CheckBox Content="XYC" IsChecked="{Binding Value.C}"></CheckBox>
                    </DataTemplate>
                </ig:PropertyGridEditorDefinition.EditTemplate>
            </ig:PropertyGridEditorDefinition>
        </ig:XamPropertyGrid.EditorDefinitions>
    </ig:XamPropertyGrid>
 
At the start, I set the selected object for PropertyGrid like this:
 
public MainWindow()
    {
        InitializeComponent();

        ClassA a = new ClassA();
        a.B = new ClassB();

        pGrid.SelectedObject = a;

    }
 
But when I check the Checkbox, Property C won't change. As far as I debugged the Value property inside Editor DataTemplate is null. (I put a converter inside Binding to check that.)
 
Thank you in Advance.
