在 ItemsControl ResourceDictionary 中设置 deledate

首先，让我向您展示我的代码是如何剪切的。

我在xaml UC（eventsUC.xaml）中有以下代码：

<UserControl x:Class="QuimeO.UserControls.Lists.EventsListUC"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
         xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
         xmlns:ToggleSwitch="clr-namespace:ToggleSwitch;assembly=ToggleSwitch" 
         mc:Ignorable="d" 
         Width="477"
         >
<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="*" />
        <RowDefinition Height="Auto"/>
    </Grid.RowDefinitions>
    <ScrollViewer HorizontalScrollBarVisibility="Disabled" Width="auto" VerticalScrollBarVisibility="Auto" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
        <ItemsControl Grid.Row="0" BorderThickness="0" x:Name="eventsList" ScrollViewer.VerticalScrollBarVisibility="Auto" HorizontalContentAlignment="Stretch" ScrollViewer.HorizontalScrollBarVisibility="Disabled">
            <ItemsControl.Resources>
                <ResourceDictionary x:Name="eventslisttempplate" Source="EventsListTemplate.xaml"  />
            </ItemsControl.Resources>
        </ItemsControl>
    </ScrollViewer>...

My EventsListTemplate.xaml 如下所示：

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                    x:Class="QuimeO.UserControls.Lists.EventsListTemplate"
                    xmlns:apiNamespace="clr-namespace:QuimeO.DBO"
                    >
    <DataTemplate DataType="{x:Type apiNamespace:EventsDictionary}">
        <StackPanel Orientation="Vertical">
            <Border BorderBrush="LightGray" BorderThickness="0,0,0,1" Margin="0,5,0,0">
                <TextBlock HorizontalAlignment="Right" Foreground="Gray" Text="{Binding FormatedDate}" FontSize="14"></TextBlock>
            </Border>
            <ListView Grid.Row="0" x:Name="eventsList" ItemsSource="{Binding Events}" BorderThickness="0" MouseDoubleClick="eventsList_MouseDoubleClick">
            </ListView>
        </StackPanel>
    </DataTemplate>
</ResourceDictionary>

我的 EventsListTemplate.xaml.cs 隐藏的代码如下所示

public partial class EventsListTemplate : ResourceDictionary
    {
        public Delegate MainWindowControlPointer;
        private void eventsList_MouseDoubleClick(object sender, MouseButtonEventArgs e)
        {
            var ev = ((sender as ListView).SelectedItem as ListViewItem).DataContext as Event;
            System.Diagnostics.Debug.WriteLine(ev.Name);
            this.MainWindowControlPointer.DynamicInvoke(ev.Ancestors.Root, new Element() { Category = ev.Category, Id = ev.Id, Name = ev.Name });
        }
    }

当我在模板中单击列表视图的某个项目时，它会触发eventsList_MouseDoubleCkick，我可以检索我的事件。

但是，我想在创建模板的 UC 中触发一个操作（第一个源代码块）。

为此，我只想在我的模板中创建一个委托（技术上，在理想世界中，类似于"this.rd_eventslisttemplate。主窗口控件指针 = ...'").但是，我不知道该怎么做，或者这是否可能。
