First of all, I know about this topic: How to make context menu work for windows phone?
But this way is SOO complicated... So I have this XAML code:
<StackPanel Name="friendsGrid" Margin="0,0,0,0" Background="Transparent">
<ListBox Name="friendsListBox" FontSize="32" Tap="friendsListBox_Tap">
<toolkit:ContextMenuService.ContextMenu>
<toolkit:ContextMenu Name="MyContextMenu" Opened="MyContextMenu_Opened">
<toolkit:MenuItem Header="action" Click="contextMenuAction_Click"/>
</toolkit:ContextMenu>
</toolkit:ContextMenuService.ContextMenu>
</ListBox>
</StackPanel>
And I'm filling the list like this:
this.friendsListBox.Items.Add(friend.serviceName);
But, of course, when I do longtap, the context menu appears and selects the whole List, not only one item.
Is there some easy way to recognize the item was tapped? Thanks
BTW, I found this method, but contextMenuListItem doesn't recieve anything, it's still null:
ListBoxItem contextMenuListItem = friendsListBox.ItemContainerGenerator.ContainerFromItem((sender as ContextMenu).DataContext) as ListBoxItem;
You should put ContextMenu block into your ItemTemplate (not ListBox block).
Here short sample.
XAML:
<ListBox Name="TestList" Margin="26,0,26,0" Height="380" >
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding}">
<toolkit:ContextMenuService.ContextMenu>
<toolkit:ContextMenu Name="ContextMenu" >
<toolkit:MenuItem Name="Edit" Header="Edit" Click="Edit_Click"/>
<toolkit:MenuItem Name="Delete" Header="Delete" Click="Delete_Click"/>
</toolkit:ContextMenu>
</toolkit:ContextMenuService.ContextMenu>
</TextBlock>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Code:
public List<string> Items = new List<string>
{
"Item1",
"Item2",
"Item3",
"Item4",
"Item5",
};
// Constructor
public MainPage()
{
InitializeComponent();
TestList.ItemsSource = Items;
}
private void Edit_Click(object sender, RoutedEventArgs e)
{
if (TestList.ItemContainerGenerator == null) return;
var selectedListBoxItem = TestList.ItemContainerGenerator.ContainerFromItem(((MenuItem) sender).DataContext) as ListBoxItem;
if (selectedListBoxItem == null) return;
var selectedIndex = TestList.ItemContainerGenerator.IndexFromContainer(selectedListBoxItem);
MessageBox.Show(Items[selectedIndex]);
}
Hope this helps.
