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.

Change the TabItems layout when the TabControl OverflowMode="Wrap" with TabStripPlacement="Bottom" :
1. Let's say the wrap results in 3 lines. What we would expect is line 1 and 2 to be filling the entire width and line 3 to be partially filled. What we experience is line 1 partially filled and lines 2 and 3 filling the entire width 
2. When clicking on an item the lines swap around. The partially filled line can end up on top, in the middle or on the bottom. Clicking on items that cause tab rows to move up should re-flow the wrap.
3. Ideally - to look good - the logic should stretch the 'complete' rows to the entire width - i.e. it should adjust tab sizes to fill the entire width available on 'full' rows.
Won't Fix

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.

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

Tabcontrol doesn't work correctly when we set the properties TabOrientation="Vertical" and AllTabsEqualHeight="False". The Header are always Aligned left no matter the value align property.

DECLINED: This issue cannot be reproduced with R3 2016 release version.

Basically I want to see only full tabs, not part of a tab.  Those tabs that aren't visible should be displayed in the dropdown only, the tabs that are visible should not be displayed in the dropdown, and the tab control should resize (to a shorter width) to only show tabs that are visible

The selected item could have a different header template so that it will be differentiated from the rest of the  tabs.
