How to AllowDragReorder when ItemsSource is set to binding?

[Roman]

I'm trying to enable tabs reordering, but it works only when items are set in xaml.

This works:

<t:RadTabControl AllowDragReorder="True" x:Name="radTabControl1">
    <t:RadTabItem Header="item1" />
    <t:RadTabItem Header="item2" />
    <t:RadTabItem Header="item3" />
</t:RadTabControl>

And this don't

<t:RadTabControl AllowDragReorder="True" x:Name="radTabControl1" ItemsSource="{Binding list}" />

How to make this work with binding?

Hello Roman,

I am unable to reproduce this issue in our environment. Could you please have a look at my test project and let me know if I am have missed something ?

My code didn't work because I used List instead of ObservableCollection

Hello Roman,

Yes. I forgot to mention that ObservableCollection<> is very suitable in scenarios when you make changes both in the UI and in the ViewModel. ObservableCollection implements ICollectionChanged and IPropertyChanged interface and this way every change in the ViewModel is automatically reflected in the UI.

The DLLs you included in this demo are version 2011.1.0315.40.
I am currenting using version 2011.2.0920.35.

RadTabControl reordering is not working for my current version through Data Binding on the ItemsSource. If I reference your version of DLLs, it works.

Thanks,

Corey
