Loaded event of the RadTabItem's content is fired twice in WPF.

Declined: The behaviour is caused due to the way how the WPF framework operates with ContentControl and their Content property(the RadTabItem is HeaderedContentControl which derives from ContentControl). The Content property is automatically registered to the LogicalTree when it is set, this is causing the first loaded event to be fired. After a selection is made the RadTabControl inserts/visualizes the Content of its selected RadTabItem in its ContentPresenter, this causes the control to fire its loaded event as it is loaded into the VisualTree.

private void Content_Loaded(object sender, RoutedEventArgs e)
{
	if (VisualTreeHelper.GetParent(sender as DependencyObject) != null)
	{
		// Execute the logic for LoadedEvent.
	}
}

When navigating with tab key (without setting tabindex) first highlights the RadTabItem then its content. Setting a tabindex on a control in the tabItem`s content works the opposite way

Scrolling in TabStrip does not work well when TabStripPlacement=Left or Bottom and  ScrollMode=Item. Pressing the Scroll Buttons scrolls the entire set of tabs.

In the VS2010 designer the selected tab is the last one even if the SelectedIndex proeprty of the TabControl is set to 0. The issue can be reprodiced in a scenario where the RadTabControl is defined in a RadWindow control.

When the SelectedIndex property is read during animation the CLR wrapper will throw InvalidCastException because of invalid cast to int. The object returned from GetValue is DeferredReference object.

When the window of an application that has a TabControl with Left/Right TabStripPlacement is resized, the measure of the TabStrip is incorrect and the ScrollButtons are in Disabled state. All Tabs should be visible when the window is in its normal state and should be scrollable.
 
========================
Possible workaround:
Inherit RadTabControl and override

  protected override void OnScrollButtonsVisibilityChanged()
        {
            if (this.ScrollViewer != null)
            {
                RadDockPanel parentDock = this.ScrollViewer.Parent as RadDockPanel;
                if (parentDock != null)
                {
                    // Dispatcher is because Measure should be called outside other Measure phase.
                    this.Dispatcher.BeginInvoke(new Action(() =>
                    {
                        parentDock.InvalidateMeasure();
                    }));
                }
            }
        }

The CommonStates of the control aren't applied and this is why you can't add any storyboards for the normal and disabled state of the control.

When you have implicit DataTemplates applied to items the binding expression is lost on selection changed.
