Hello, I have a Silverlight 3 application where I use a tab control and I want to implement the navigational framework into it. The tabs on my page are created dynamically by the user, saying this

TabItem ti = new TabItem();
Frame frame = new Frame();
ti.Content = frame;
MyTabs.Items.Add(ti);

When the user clicks a link, I want content to load into whichever tab is currently selected, so I say this

HyperlinkButton btn = sender as HyperlinkButton;
string url = btn.Tag.ToString();
Frame frame = MyTabs.SelectedContent as Frame;
frame.Navigate(new Uri(url, UriKind.Relative));

The current tab loads the page into its frame correctly. However, as I click through the other tabs, they also have loaded the page into their frames, so all open tabs have the exact same content. So for example, the user has 5 tabs open. They click a link, and the currently selected tab loads a Page into its Frame. If they go to one of the four other tabs, they see that those tabs also loaded the same Page. How can I make sure that only the selected tab gets its new Page and not the other tabs? Thanks to anyone who can help.
