我最近重写了DevXpress WPF网格,给自己一个SelectedObject属性,我可以从松散绑定的ViewModel访问它.

我已经创建了一个SelectedObject依赖项属性,并在我的XAML中绑定了OneWayToSource.

Everthing工作正常,但如果我尝试将其设为ReadOnly(为了完整性),我会收到编译错误并说我无法绑定到ReadOnly属性.下面的代码编译,我已经包括(但重新列出)我尝试获取属性ReadOnly时尝试的位.

有人可以帮忙吗？

我重写的控件的依赖属性如下所示:

  //public static readonly DependencyPropertyKey SelectedRowKey = DependencyProperty.RegisterReadOnly("SelectedObject", typeof(object), typeof(MyGrid), new PropertyMetadata(null));
//public static readonly DependencyProperty SelectedObjectProperty = SelectedRowKey.DependencyProperty;

public readonly static DependencyProperty SelectedObjectProperty = DependencyProperty.Register("SelectedObject", typeof(object), typeof(MyGrid), new PropertyMetadata(null));

public object SelectedObject
{
    get
    {

        return GetValue(SelectedObjectProperty);
    }
    set
    {
        throw new NotImplementedException();
    }
}

XAML是:

 <StackPanel>
  <devxgrid:MyGrid AutoPopulateColumns="True" DataSource="{Binding Animals}" SelectedObject="{Binding MyObject, Mode=OneWayToSource}" Width="300" Height="300">
    <devxgrid:MyGrid.View>
        <MyGrid:TableView AllowEditing="False" Name="GridView" AutoWidth="True" />
    </devxgrid:MyGrid.View>
 </devxgrid:MyGrid>
</StackPanel>
