WPF TabContol problem

[Jacobus01]

Hi, I have a wpf window containing a Tabcontol with 2 tab items. Both tab items contain a datagrid and some additional buttons and textboxes. I can't seem to find an event for the tab control that only fires when you select the tab item at the top. SelectionChanged fires for any item that I select in the tab item. I need my datagrid to bind to a new datatable whenever its host tab is selected. Please Help!

A few days ago JSOP mentioned something like this. Look here[^]

I created a new TabItem class, like so:

public class UDPTabItem : TabItem
{
	public bool           IsActive { get; set; }

	//--------------------------------------------------------------------------------
	//--------------------------------------------------------------------------------
	// Create a custom routed event by first registering a RoutedEventID.  This event 
	// uses the bubbling routing strategy
	public static readonly RoutedEvent ActivateEvent = EventManager.RegisterRoutedEvent("Activate", 
                                           RoutingStrategy.Bubble, typeof(RoutedEventHandler), typeof(UDPTabItem));
	// Provide CLR accessors for the events
	public event RoutedEventHandler Activate
	{
		add    { AddHandler(ActivateEvent, value);    } 
		remove { RemoveHandler(ActivateEvent, value); }
	}
	// These methods raise the events
	private void RaiseActivateEvent()
	{
		RoutedEventArgs eventArgs = new RoutedEventArgs(UDPTabItem.ActivateEvent);
		RaiseEvent(eventArgs);
	}


	//--------------------------------------------------------------------------------
	//--------------------------------------------------------------------------------
	public static readonly RoutedEvent DeactivateEvent = EventManager.RegisterRoutedEvent("Deactivate", 
                              RoutingStrategy.Bubble, typeof(RoutedEventHandler), typeof(UDPTabItem));
	public event RoutedEventHandler Deactivate
	{
		add    { AddHandler(DeactivateEvent, value);    } 
		remove { RemoveHandler(DeactivateEvent, value); }
	}
	private void RaiseDeactivateEvent()
	{
		RoutedEventArgs eventArgs = new RoutedEventArgs(UDPTabItem.DeactivateEvent);
		RaiseEvent(eventArgs);
	}


	//--------------------------------------------------------------------------------
	/// <summary>
	/// 
	/// </summary>
	public UDPTabItem()
	{
		this.IsActive = false;
	}

	//--------------------------------------------------------------------------------
	/// <summary>
	/// 
	/// </summary>
	/// <param name="activate"></param>
	public void ActivateTab(bool activate)
	{
		IsActive = activate;
		if (this.IsActive)
		{
			RaiseActivateEvent();
		}
		else
		{
			RaiseDeactivateEvent();
		}
	}

	//--------------------------------------------------------------------------------
	/// <summary>
	/// 
	/// </summary>
	/// <param name="e"></param>
	protected override void

Thank you very much. I'm still new to WPF and I'm still getting used to the new event model. So far I'm quite impressed...

I've only been doing it since April, and I'm not impressed...
