Hi Chris,

There is no scrolling event exposed, but you can use the VisualTreeHelper class to find the left and right scroll buttons.

public MainPage()

{

InitializeComponent();

// populate the TabControl with some items to force the scroll button to appear

this.tabControl1.ItemsSource = Enumerable.Range(0, 50);

this.Loaded += new RoutedEventHandler(MainPage_Loaded);

}

void MainPage_Loaded(object sender, RoutedEventArgs e)

{

this.Dispatcher.BeginInvoke(() =>

{

// Get the first element in RadTabControl's visual tree

var root = VisualTreeHelper.GetChild(this.tabControl1, 0) as Panel;

// Find the LeftScrollButtonElement and RightScrollButtonElement

RepeatButton leftScrollButtonElement = root.FindName("LeftScrollButtonElement") as RepeatButton;

Debug.Assert(leftScrollButtonElement != null);

RepeatButton rightScrollButtonElement = root.FindName("RightScrollButtonElement") as RepeatButton;

Debug.Assert(rightScrollButtonElement != null);

// Subscribe to their click event

leftScrollButtonElement.Click += new RoutedEventHandler(LeftScrollButtonElement_Click);

rightScrollButtonElement.Click += new RoutedEventHandler(RightScrollButtonElement_Click);

});

}

private void RightScrollButtonElement_Click(object sender, RoutedEventArgs e)

{

MessageBox.Show("RightScrollButton clicked");

}

private void LeftScrollButtonElement_Click(object sender, RoutedEventArgs e)

{

MessageBox.Show("LeftScrollButton clicked");

}

Give it a try and let me know if this helps.
