Mapping ContextMenu

Question

I find it difficult to find good documentation for this, despite some time.

I would like to have a context menu in my application that replicates the behavior observed using other tap-and-hold context menus, for example, attaching an application to the start screen from the list of applications.

Here is my context menu:

<toolkit:ContextMenuService.ContextMenu> <toolkit:ContextMenu x:Name="sectionContextMenu"> <toolkit:MenuItem Header="Hide this section from this list" /> </toolkit:ContextMenu> </toolkit:ContextMenuService.ContextMenu> 

How do I show it?

Answer 1

The context menu should be attached to the element that you want the user to press and hold.

 <Border Margin="0,12" BorderBrush="{StaticResource PhoneForegroundBrush}" BorderThickness="2" Background="Transparent" VerticalAlignment="Center" Padding="16"> <toolkit:ContextMenuService.ContextMenu> <toolkit:ContextMenu x:Name="sectionContextMenu"> <toolkit:MenuItem Header="Hide this section from this list" /> </toolkit:ContextMenu> </toolkit:ContextMenuService.ContextMenu> <TextBlock Text="Tap and hold here to invoke a ContextMenu" Style="{StaticResource PhoneTextNormalStyle}"/> </Border> 

Now the user can call the context menu by pressing and holding the contents of this Border element.

Unique context menu for different items depending on content.

 private ContextMenu CreateContextMenu(ListBoxItem lbi) { ContextMenu contextMenu = new ContextMenu(); ContextMenuService.SetContextMenu(lbi, contextMenu); contextMenu.Padding = new Thickness(0); string item_1 = "item 1"; if(lbi.Content is string) { item_1 = lbi.Content as string; } contextMenu.ItemsSource = new List<string> { item_1, "item 2", "item 3" }; contextMenu.IsOpen = true; return contextMenu; } private void Results_SelectionChanged(object sender, SelectionChangedEventArgs e) { if (Results.SelectedIndex == -1) return; int index = Results.SelectedIndex; ListBoxItem lbi = Results.ItemContainerGenerator.ContainerFromIndex(index) as ListBoxItem; CreateContextMenu(lbi); Results.SelectedIndex = -1; }
