我有Page,当我点击它的空白部分时,它会失去焦点。我尝试将边框作为背景,但是当我点击它时也会失去焦点。为什么会这样?
我真正需要做的是在用户打开AppBar或设置超级按钮时禁用WebView
一些示例代码来演示该问题(观察输出窗口):
XAML:
<Page
x:Name="Pagey"
x:Class="FocusTest.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:FocusTest"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d" GotFocus="Focus" LostFocus="LoseFocus">
<Grid x:Name="RootGrid" Background="{StaticResource ApplicationPageBackgroundThemeBrush}" GotFocus="Focus" LostFocus="LoseFocus">
<StackPanel>
<Button x:Name="Clicky" Content="Clicky" GotFocus="Focus" LostFocus="LoseFocus" HorizontalAlignment="Center"></Button>
<Border x:Name="Border" Width="100" Height="100" Background="Red" GotFocus="Focus" LostFocus="LoseFocus"></Border>
<Button x:Name="Clicky2" Content="Clicky2" GotFocus="Focus" LostFocus="LoseFocus" HorizontalAlignment="Center"></Button>
</StackPanel>
</Grid>
</Page>
后面的代码:
using System.Diagnostics;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;
namespace FocusTest
{
public sealed partial class MainPage : Page
{
public MainPage()
{
this.InitializeComponent();
}
void Focus(object sender, RoutedEventArgs e)
{
Debug.WriteLine("Focus({0})", (sender as FrameworkElement).Name);
}
void LoseFocus(object sender, RoutedEventArgs e)
{
Debug.WriteLine("LoseFocus({0})", (sender as FrameworkElement).Name);
}
}
}
最佳答案
看起来您的Border
在RootGrid
内部,因此每次点击Border's tap event
都会发生,并且会触发LostFocus
事件。更好的是,您可以在同一LostFocus
上设置RootGrid
事件。然后它可能会正常工作。请尝试一下。
谢谢。
