how to get swipe in windows phone 7

I want to swipe images in windows phone 7. Where do I begin from开发者_开发百科?

You can use the GestureService in the Silverlight Control Toolkit for Windows Phone 7. In your UI element, add the following piece of code (after you have referenced the toolkit's DLL in your WP7 project) -

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

Implement the handler OnFlick in the code-behind file, like so -

private void OnFlick(object sender, FlickGestureEventArgs e)
{
   var vm = DataContext as SelectedCatalogViewModel;
   if (vm != null)
   {
      // User flicked towards left
      if (e.HorizontalVelocity < 0)
      {
         // Load the next image 
         LoadNextPage(null);
      }

      // User flicked towards right
      if (e.HorizontalVelocity > 0)
      {
         // Load the previous image
         LoadPreviousPage();
      }
   }
}

Hope this helps, indyfromoz

If you don't want to use the silverlight toolkit you can use the XNA framework.

Try this:

using Microsoft.Phone.Controls;

public partial class MyControl
{
    public MyControl()
    {
        InitializeComponent();

        var gl = GestureService.GetGestureListener(asd);
        gl.Flick += new EventHandler<FlickGestureEventArgs>(GestureListener_Flick);
    }

    private void GestureListener_Flick(object sender, FlickGestureEventArgs e)
    {
        if (e.Direction == Orientation.Horizontal)
        {
            if (e.HorizontalVelocity < 0) // determine direction (Right > 0)
            {
                //Some Action
            }
            else
            {
                //Some Action
            }
        }
    }
}
