Question

首先，我试图获取ListView的行详细信息（就像RowDetailsTemplate一样）功能，并且正在使用这种方法：

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

自定义功能在此处定义：

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");
        }
    }
}

和主要样式：

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

存在的内容定义如下：

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

我将“可见性”设置为“可见”，以确保不会发生绑定问题。

我正在这样使用它：

<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>

我的项目设置为使用wpf自定义控件，并且其中包含程序集：ThemeInfo节。

我不能使用

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

这似乎为其他人解决了此问题，因为GridViewWithRowDetails类是从GridView派生的，因此它缺少DefaultStyleKeyProperty。

我认为DefaultStyleKeyProperty是为基于Control的类定义的。

我不得不提一下，如果我在MainApp中执行所有这些操作，那么效果很好。

任何提示将不胜感激。

好，所以MahApps正在发生碰撞。在我的主要应用程序App.xaml中，

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

我删除了它，取而代之的是我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">

</ResourceDictionary>

无论如何，这是一件很奇怪的事情，因为ListView.xaml仍然存在，但是我将继续对此进行调查。目前，我有一个工作版本。
