WP8 Tap the image to get the selected item in longlistselector

Question

I created a LongListSelector with textblock and an image,then How do I tap the image to show selected item name in my list, and tap the item name to show messagebox? Below i

Answer 1

sender isn't the LongListSelector but the image on which the user tapped, hence the null error.

Basically, you just want to retrieve the item on which the user has tapped? In that case, use the DataContext property of the tapped control to retrieve it:

private void GetName_Tap(object sender, System.Windows.Input.GestureEventArgs e)
{
   var element = (FrameworkElement)sender;
   StaffData data = (StaffData)element.DataContext;
   MessageBox.Show(data.Name);
}

(FrameworkElement is the base type of every UI control. Using that, you don't have to worry about whether it's an image, a textblock, ...)
