Moving RadTabItem

[Hela]

Hello,

I am relatively new to SilverLight Applications and I'd like to create a tab control in which the  RadTabItem can be moved.
So when the TabItem is clicked then dragged, it can be placed in the TabControl  once the mouse is released. 
       
Thanks
Héla

Hello Hela,

As far as i understand your question you want to do something similar to one of our online demos. Please check this demo at http://demos.telerik.com/silverlight/#TabControl/DragReorder and tell us if this works for you.

On a little different note. The dragReorder works if the tab items are created in the xaml. I created tab items on the run (binding) and I am not able to reorder by dragging them. Am I missing anything?  Below is the snapshot of my code.

 

 

<tnav:RadTabControl x:Name="MyTab" AllowDragReorder="True" ItemsSource="{Binding list, Converter={StaticResource tc}}"/>

public class TabConverter : IValueConverter
{

 

 

 

    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)

 

 

    {

 

        List<PortfolioTab> source = value as List<PortfolioTab>;

 

       DataTemplate dt = App.Current.Resources["tabHeader"] as DataTemplate;
        if (source != null)
        {

 

 

 

            List<RadTabItem> result = new List<RadTabItem>();
            host = someUserControl;
            foreach (PortfolioTab tab in source)
            {

 

 

 

                result.Add(

 

 

                new RadTabItem()

                 {

                    Tag = tab.TabID,

                    Header = tab.TabTitle,

                    Content = host

                });

             }

 

            return result;
        }

 

 

 

 

        return null;
    }

 

 

 

 

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)

    {

 

        throw new NotImplementedException();
    }

 

 

}

Hi Deven,

You have to return an ObservableCollection<RadTabItem> instead of a List<RadTabItem>. While reordering the tabs the ItemsSource changes and the ObservableCollection will notice the changes.

I have attached a sample project that demonstrates the usage of ObservableCollection. Have a look at it and try the approach in your application.
Let me know if you experience any additional problems.

That was spot on. It was silly on my part to not think of ObsColl.

Thanks much for your time.
