Win8 XAML Grid which column and row was tapped

Question

In a windows store app I have a grid with a lot of columns and rows

        <Grid x:Name="gridContainer" 
              Background="Transparent"
              Tapped="gridContainer_Tapped">
            <Grid.RowDefinitions>
                <RowDefinition/>
                <RowDefinition/>
                ...
            </Grid.RowDefinitions>

            <Grid.ColumnDefinitions>
                <ColumnDefinition/>
                ...
            </Grid.ColumnDefinitions>
       </Grid>

and listening to Grid Tapped event.

private void gridContainer_Tapped(object sender, TappedRoutedEventArgs e)
{

}

Is it possible to determine which column and row was tapped without adding additinal transparet elements and tracking their tapped events?

Answer 1

If you have anything inside those cells you can do this:

private void gridContainer_Tapped(object sender, TappedRoutedEventArgs e)
{
   if(e.OriginalSource is FrameworkElement)
   {
      var col = Grid.GetColumn(e.OriginalSource as FrameworkElement);
   }
}
