我在Windows 8.1应用程序上有一个StackPanel
,我想添加一个Mouse-Over
函数。如果我理解正确,Windows 8.1 应用程序上的类似功能是 PointerEntered/PointerExited
.例如,如何使用这些功能获取TextBlock
的"项目"文本?
编辑:我基本上想在鼠标悬停时获取TextBlock
的句柄,以便我可以获取或设置它的属性(文本等)。
这是我C#
函数
private void itemGridView_PointerEntered(object sender, PointerRoutedEventArgs e)
{
}
和我的 XAML 代码:
<GridView
x:Name="itemGridView"
AutomationProperties.AutomationId="ItemGridView"
AutomationProperties.Name="Items In Group"
TabIndex="1"
Grid.RowSpan="2"
Padding="120,126,120,50"
ItemsSource="{Binding Source={StaticResource itemsViewSource}}"
SelectionMode="None"
IsSwipeEnabled="false"
IsItemClickEnabled="True"
ItemClick="ItemView_ItemClick" PointerEntered="itemGridView_PointerEntered">
<GridView.ItemTemplate>
<DataTemplate>
<Grid Height="110" Width="480" Margin="10">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Border Background="{ThemeResource ListViewItemPlaceholderBackgroundThemeBrush}" Width="110" Height="110">
<Image x:Name="ImageItemName" Source="{Binding ImagePath}" Stretch="UniformToFill" AutomationProperties.Name="{Binding Title}"/>
</Border>
<StackPanel x:Name="stackPanel1" Grid.Column="1" VerticalAlignment="Top" Margin="10,0,0,0">
<TextBlock x:Name="ItemTitleText" Text="{Binding Title}" Style="{StaticResource TitleTextBlockStyle}" TextWrapping="NoWrap"/>
<TextBlock Text="{Binding Subtitle}" Style="{StaticResource CaptionTextBlockStyle}" TextWrapping="NoWrap"/>
<TextBlock x:Name="ItemDescText" Text="{Binding Description}" Style="{StaticResource BodyTextBlockStyle}" MaxHeight="60"/>
</StackPanel>
</Grid>
</DataTemplate>
</GridView.ItemTemplate>
<GridView.Header>
<StackPanel Width="480" Margin="0,4,14,0">
<TextBlock x:Name="TitleTextBlock" Text="{Binding Subtitle}" Margin="0,0,0,20" Style="{StaticResource SubheaderTextBlockStyle}" MaxHeight="60"/>
<Image x:Name="imageName" Source="{Binding ImagePath}" Height="400" Margin="0,0,0,20" Stretch="UniformToFill" AutomationProperties.Name="{Binding Title}"/>
<TextBlock x:Name="DescTextBlock" Text="{Binding Description}" Margin="0,0,0,0" Style="{StaticResource BodyTextBlockStyle}"/>
</StackPanel>
</GridView.Header>
<GridView.ItemContainerStyle>
<Style TargetType="FrameworkElement">
<Setter Property="Margin" Value="52,0,0,2"/>
</Style>
</GridView.ItemContainerStyle>
</GridView>
使用属性Children
来获取子元素的UIElementCollection
。
面板.儿童属性。MSDN
private void StackPanel_PointerEntered(object sender, PointerRoutedEventArgs e)
{
var values = new List<string>();
var sp = sender as StackPanel;
if (sp != null)
{
foreach (var child in sp.Children)
{
var tb = child as TextBlock;
if (tb != null)
{
values.Add(tb.Text);
}
}
}
}
