Click event of a Button in the HeaderTemplate is not fired properly when another button outside the tab has IsDefault property set to true

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

When the RadTabControl AllowDragReorder property is set to True and the control contains multiple rows with tabs, the dragging operation cannot be properly executed and completed.

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.

Pressing "Tab" key does not change the focus when there are several controls in a TabItem.

SelectedItem does not respect the Reset collection changed action.

Add a visual state for the selected tab item representation in the DropDown menu of the TabControl.

Using  ArcGIS API for Silverlight/WPF version 2.1 in the TabControl throws exception in design-time

Can't apply transitions when changing the visual state of the RadTabControl or its items

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.

The TabControl ScrollMode property doesn't work as expected when set to "Item"

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

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.

TabControl: The tab items and their content are not disposed correctly due to the RadTabItemAutoamtionPeer.

Selecting tabs with same names from the drop down menu always selects the first one.

The workaround is to set the IsContentPreserved of the RadTabControl to True.

The scroll buttons are visible when the visible area is enough to display all tabs and the TabStripPlacement is set to Left/Right.

When a RadDocking is located inside a RadTabControl and the RadPaneGroup contains only one RadPane the content is scrolled(if located inside a ScrollViewer)

When a TabItem has a width (and the TabControl - don't) and if you try to resize the window so that the width of the window is less than the width of the TabItem - the TabItems start jumping

The SelectedTabContent is not added when the control is loaded in memory and a we try to create a ImageSource out of the UserControl hosting the TabControl
