wpf – 两个自定义依赖项之间的绑定

class row : dependencyobject
{
   // this is a dp property
   public static readonly dependencyproperty widthproperty = dependencyproperty.register...
}

class cell : dependencyobject
{

   public static readonly dependencyproperty dataproperty = dependencyproperty.register....
}

class customGridView:Control
{
  List<Row>Rows { get;set;}
  List<Cell> Cells { get;set;}
}

现在我想将一个行的实例绑定到cell.data属性,也是这样的：

<customGridView>
 <row x:name:row1 width=200/> (this is a class that derives for dependencyobject)
 <row .../>
 <cell data={Binding ElementName=row1}/> (this is another class that derives from dependencyobj and tries to bind to entire instance of row class)
 <cell ..../>
 <cell ..../>
</customGridView/>

任何帮助？

根据需要,这是cell.data的dp属性：

public Row Data
    {
        get { return (Row)GetValue(DataProperty); }
        set { SetValue(DataProperty,value); }
    }

    // Using a DependencyProperty as the backing store for ColumnName.  This enables animation,styling,binding,etc...
    public static readonly DependencyProperty DataProperty=
        DependencyProperty.Register("Data",typeof(Row),typeof(Cell),new PropertyMetadata(null));
