ComponentResourceKey表示ListViewItem

Question

首先，我正在尝试获取ListView的行详细信息(就像ListView)功能，并且我使用了以下方法：

gridview-equivalent-of-the-datagrids-row-details-template

自定义功能在此处定义为，

public class GridViewWithRowDetails : GridView
{
    public static DataTemplate GetRowDetailsTemplate(DependencyObject obj)
    {
        return (DataTemplate)obj.GetValue(RowDetailsTemplateProperty);
    }

    public static void SetRowDetailsTemplate(DependencyObject obj, DataTemplate value)
    {
        obj.SetValue(RowDetailsTemplateProperty, value);
    }

    public static readonly DependencyProperty RowDetailsTemplateProperty =
        DependencyProperty.RegisterAttached("RowDetailsTemplate", typeof(DataTemplate), typeof(GridViewWithRowDetails), new UIPropertyMetadata());


    protected override void PrepareItem(ListViewItem item)
    {
        base.PrepareItem(item);
        item.SetValue(RowDetailsTemplateProperty, this.GetValue(RowDetailsTemplateProperty));

    }

    protected override object ItemContainerDefaultStyleKey
    {
        get
        {
            return new ComponentResourceKey(this.GetType(), "ItemContainerStyleKey");
        }
    }
}

和主要风格:

<Style x:Key="{ComponentResourceKey TypeInTargetAssembly={x:Type themes:GridViewWithRowDetails}, 
       ResourceId=ItemContainerStyleKey}"
       TargetType="{x:Type ListViewItem}">

现有内容的定义如下：

<ContentPresenter ContentTemplate="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=ListViewItem}, Path=(themes:GridViewWithRowDetails.RowDetailsTemplate), Mode=TwoWay}" 
                                              Visibility="Visible"
                                              Grid.Row="2" 
                                              Content="{TemplateBinding Content}"/>

我已经将可见性设置为“可见的”，以确保没有绑定问题会干扰。

我就是这样用的：

<themes:GridViewWithRowDetails>
    <themes:GridViewWithRowDetails.RowDetailsTemplate>
         <DataTemplate>
               <StackPanel Background="Black">
                      <TextBox Margin="10, 2" Text="text"/>
               </StackPanel>
          </DataTemplate>
    </themes:GridViewWithRowDetails.RowDetailsTemplate>

     <themes:GridViewWithRowDetails.Columns>
     ..........................
     </themes:GridViewWithRowDetails.Columns>

</themes:GridViewWithRowDetails>

我的项目是为wpf自定义控件设置的，它包含程序集: ThemeInfo部分。

我不能用

DefaultStyleKeyProperty.OverrideMetadata(typeof(MyCustomControl), 
        new FrameworkPropertyMetadata(typeof(MyCustomControl)));

这似乎解决了其他人的这个问题，因为GridViewWithRowDetails类是从GridView派生的，因此缺乏DefaultStyleKeyProperty。

我认为DefaultStyleKeyProperty是为基于控件的类定义的。

我必须指出，如果我在MainApp上做了所有这一切，它就能正常工作。

如有任何提示，将不胜感激。

好的，所以MahApps在碰撞。在我的主要应用程序的App.xaml中

<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />

我删除了它，而是定义了一个具有以下内容的新字典：

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

无论如何，这是一件奇怪的事情，因为ListView.xaml还在那里，但我将继续研究这个问题。目前，我有一个有用的版本。
