WP7-ContextMenu在超链接上不显示

Question

I'm trying to programmatically add a ContextMenu to a Hyperlink. I've searched in the documentation and in forums, and seems that the correct solution should be this:

var link = new Hyperlink();
link.Inlines.Add(new Run() { Text = linkText });
link.FontWeight = FontWeights.Bold;
link.TargetName = linkText;
link.Click += new RoutedEventHandler(link_Click);

ContextMenu menu = new ContextMenu();
MenuItem item = new MenuItem();
item.Click += new RoutedEventHandler(CopyLink);
item.Header = "copy link";
item.Tag = linkText;
menu.Items.Add(item);
ContextMenuService.SetContextMenu(link, menu);

This code compiles and does not throw any exception. I've tested and the ContextMenu is indeed added to the Hyperlink. The problem is that it will not show anytime. I can tap & hold the link all the time of the world and the menu will not appear. Also tried to add a listener with GestureService and GestureListener, but the Hold event does not fire at all.

Anyone can help me? Thanks.

You can't do ContextMenu s on Hyperlink s . You can do it on a HyperlinkButton , though. I'm not exactly sure of the reason, but it does work. Depending on what you're trying to do, HyperlinkButton may have been what you wanted anyway ( Hyperlink is usually only used inside documents of text).

I just found the answer while reading the Windows Phone 7.5 Unleashed book by Daniel Vaughan. My problem was that I needed to add a hyperlink in a RichTextBox, and I can only use Inlines to show text. Hyperlink is an Inline, but does not support ContextMenu. As Tim suggested, I needed to use HyperlinkButton. The solution is that there is a class called InlineUIContainer . So, this

var inline = new InlineUIContainer { Child = SomeHyperlinkButton }

made the trick for me.
