[英]WP7: Executing a NavigationService.Navigate from a MenuItem click handler from a Context menu on WP7
I have a context menu in my app and when I handle the MenuItem clicked, I want to navigate to another page. 我的应用程序中有一个上下文菜单,当我处理单击的MenuItem时,我想导航到另一个页面。 The issue I am having is that the navigation works but I don't see the other page load since the context menu remains open for the length of the click.
我遇到的问题是导航正常,但是我没有看到其他页面加载,因为上下文菜单在单击时保持打开状态。 When I hit back, the context menu closes and then I see the page I navigated to.
当我回击时,上下文菜单关闭,然后我看到导航到的页面。 What's the correct way to handle this?
处理此问题的正确方法是什么? It's almost like I need to tell the ContextMenu to close when I handle the click and then navigate to the page I want.
几乎就像我需要在处理单击然后告诉我想要的页面时告诉ContextMenu关闭。
updated with my handler code: 用我的处理程序代码更新:
private void MenuItem_Click(object sender, RoutedEventArgs e)
{
MenuItem menuItem = sender as MenuItem;
if (menuItem != null)
{
App.appData.URL = menuItem.Header.ToString();
NavigationService.Navigate(new Uri("/BrowserPage.xaml", UriKind.Relative));
}
}
XAML Code: XAML代码:
<local:MyListBox x:Name="messageListBox"
ItemsSource="{Binding ChannelMessages}"
MaxHeight="480"
>
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<toolkit:ContextMenuService.ContextMenu>
<toolkit:ContextMenu ItemsSource="{Binding URLs}">
<toolkit:ContextMenu.ItemTemplate>
<DataTemplate>
<toolkit:MenuItem Header="{Binding}" Click="MenuItem_Click"/>
</DataTemplate>
</toolkit:ContextMenu.ItemTemplate>
</toolkit:ContextMenu>
</toolkit:ContextMenuService.ContextMenu>
<TextBlock x:Name="MessageTextbox" Text="{Binding MessageFrom}" TextWrapping="Wrap">
<TextBlock.Foreground>
<SolidColorBrush Color="{StaticResource PhoneAccentColor}"/>
</TextBlock.Foreground>
</TextBlock>
<TextBlock x:Name="FromTextBox" Text="{Binding MessageText}" Margin="0,0,0,19" Width="456" FontSize="21.333" TextWrapping="Wrap"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</local:MyListBox>
Any ideas? 有任何想法吗?
Thanks 谢谢
在点击事件处理程序中设置e.Handled = true
是否有帮助?
