Get ListBox SelectedItem In RadWindow (all in code behind)

[Jonathon]

Hi,

I have a RadWindow that is displayed when a user clicks a button. In that RadWindow I have a ListBox and a Button. I want the first item in the ListBox to be selected by default, and then when they click the button, I will get the value of the ListBox item. Here is a general layout of the code I have so far:

RadWindow userSelectionWindow = new RadWindow();
            StackPanel radWindowContent = new StackPanel();
            ListBox listBox = new ListBox();
            foreach (var server in Servers)
            {
                ListBoxItem option = new ListBoxItem();
                option.Content = server.Name;
                listBox.Items.Add(option);
            }

            Binding selected = new Binding();
            selected.Mode = BindingMode.OneTime;
            selected.Source = SelectedItem;
            listBox.SetBinding(Selector.SelectedItemProperty, selected);
            radWindowContent.Children.Add(listBox);

            RadButton loginButton = new RadButton();
            loginButton.Command = new RelayCommand(CallMethod);
            loginButton.Content = "Log in";
            loginButton.Margin = new Thickness(0, 15, 0, 0);
            StyleManager.SetTheme(loginButton, new MetroTheme());
            radWindowContent.Children.Add(loginButton);

            userSelectionWindow.Content = radWindowContent;
            userSelectionWindow.WindowStartupLocation = WindowStartupLocation.CenterScreen;
            userSelectionWindow.CanMove = false;
            userSelectionWindow.ResizeMode = ResizeMode.NoResize;
            StyleManager.SetTheme(userSelectionWindow, new MetroTheme());
            userSelectionWindow.Show();

For some reason my string SelectedItem is never getting updated. Am my going about this the wrong way? What I need is the value of the SelectedItem in the ListBox after the user clicks the Log In button. I can do the functionality I need in XAML without the RadWindow, but doing all this in code behind is confusing.

Thanks,

Jonathon

Hello Jonathon,

I would suggest using the RadWindow control as a user control - please, refer to the following link - http://www.telerik.com/help/silverlight/radwindow-how-to-use-radwindow-as-user-control.html. In this way, you could define the content in the xaml.

Hope this helps.

Kind regards,
