无法将“Windows.UI.Xaml.Controls.ItemsControl"类型的对象转换为“Windows.UI.Xaml.Controls.Image" [英] Unable to cast object of type 'Windows.UI.Xaml.Controls.ItemsControl' to type 'Windows.UI.Xaml.Controls.Image'

问题描述

当我点击图像时，我在此项目控件中放置了一个点击事件以查看图像，但是当我这样做时，我收到了这个错误，我该怎么做才能修复它.我尝试更改为项目图像但不存在.

I put a event of tapped in this Item Control to see the image when I tap the image, but when I do I receive this error what I to do to fix it. I try to change to Item Image but didn't exist.

XAML 代码:

<ItemsControl x:Name="icPareoExerciseControl1" 
  HorizontalAlignment="Left" 
  VerticalAlignment="Top" 
  ItemsSource="{Binding lstPareoItem}" 
  ItemTemplate="{StaticResource ExercisePareoDataTemplate2}"
  Foreground="Black" Width="400" 
  Margin="100,0,0,0" 
  Tapped="inlineImage_Tapped"/>

代码:

   private void inlineImage_Tapped(object sender, TappedRoutedEventArgs e)
       {
          Image temp = (Image)sender;
          if (temp.DataContext is MultimediaElement)
          {



          }
        else
        {
            Image ImageToGrid = (Image)sender;
            ImageContent myImage = new ImageContent();
            myImage.ImgUri = ImageToGrid.Source.ToString();
            ImageSource imgSource = ImageToGrid.Source;
            gridGallery.Visibility = Visibility.Visible;
            stckImageMenuGallery.Visibility = Visibility.Collapsed;
            ImageGalleryUri = (imgSource as BitmapImage).UriSource.OriginalString;
            imgPopup.Source = ImageToGrid.Source;
        }
    }

推荐答案

Tapped 路由事件绑定到 ItemsControl，而不是 Image代码>.

The Tapped routed event is bound to the ItemsControl, not to the Image.

这导致此行失败:

Image temp = (Image)sender;

在这种情况下应该是:

ItemsControl temp = (ItemsControl)sender;

更改您的代码，使其绑定到您在 ItemsControl 中创建的 Image.然后第一个演员将起作用.

Alter your code so it binds to the Image you are creating in your ItemsControl. Then the first cast will work.
