Get events of Gestures in wp7

I am using a pivot page in my wp7 application. The PivotItems are added programatically. I need to get events of all the gestures. How can I get them?

And, how to know the direction of flick gesture? After swiping how to get details of the current item.

I was trying this : WP7: Questions regarding Touch Gestures. But could not add 

<toolkit:GestureService.GestureListener>
        <toolkit:GestureListener Flick="GestureListener_Flick" />
</toolkit:GestureService.GestureListener>

when I am trying to add this, an error occurs.

How can I get gesture events?

There is additional support for detecting touch in the XNA library. Trying adding the Microsoft.Xna.Framework.Input.Touch reference to your project

Include the following using statement:

using Microsoft.Xna.Framework.Input.Touch;

Subscribe to the required events in your constructor as follows:

TouchPanel.EnabledGestures = GestureType.Tap | GestureType.Flick;

On your control create an event for Manipulation Completed as follows:

ManipulationCompleted="Object_ManipulationCompleted"

You could add code to the that event method to track the type of events that have been completed with the following code:

private void Object_ManipulationCompleted(object sender, ManipulationCompletedEventArgs e)
{
    while (TouchPanel.IsGestureAvailable)
    {
        GestureSample gesture = TouchPanel.ReadGesture();

        if (gesture.GestureType == GestureType.Tap)
        {
            //Do something
        }

        if (gesture.GestureType == GestureType.Flick)
        {
            //The delta contains the direction of the flick (negative/positive)
            //gesture.Delta.Y;
            //gesture.Delta.X;
        }

    }
}

Hope this Helps
