Question

I am trying to add dynamic tabs to my application. Right now if I click a button, it will open a new page. What I want is to open this page in a new tab. But when I set up the tab content to a page , the code complains. I wanna do something like this

private void bttnGoToClientsOnClick(object sender, RoutedEventArgs e)
{
    var content = new TextBlock();
    TabItem tab = new TabItem();
    tab.Header = "Search Page";
    SearchPage sp = new SearchPage();
    tab.Content = sp;
    tabControl.Items.Add(tab);
    this.NavigationService.Navigate(sp);
}

is there any way I can convert my page to usercontrol or cast it as user control

Thank you!

It wouldn’t hurt if you were more specific here 🙂

What is SearchPage class? It doesn’t seem to be the part of the WPF framework. I googled it up on the
http://www.intersoftpt.com/ website. Is that it?

TabItem.Content needs to be of ContentControl type, which SearchPage – apparently – is not. I’m sure you need to embed this SearchPage object in some control presenter, such as a panel, before you can assign it to TabItem.Content.

Update:

Try this, then:

TabItem tab = new TabItem();
tab.Header = "Search Page";
SearchPage sp = new SearchPage();
this.NavigationService.Navigate(sp);
// ---------------------------------------------------- 
var frame = new Frame(); // !
frame.Navigate(sp);  // !
tab.Content = frame; // !
// ---------------------------------------------------- 
tabControl.Items.Add(tab);

While I believe this should work, I haven’t tested it. Please let me know if it doesn’t do the trick.
