Gridview.SelectionChanged Event Handler

I am trying to access the <Image> control from <DataTemplate> within <GridView> in gridView.SelectionChanged event or gridView.ItemClick event...So please let me know that how I can access this <image> control with all its properties, mainly Source property....

So Please go through the piece of code pasted below:

<Page.Resources>
        <DataTemplate x:Key="imageTemplate">
            <Border Background="#FF939598">
                <StackPanel>
                    <Border BorderThickness="2" BorderBrush="WhiteSmoke">
                        <Image Name="img" Source="{Binding}" Height="170" Width="210" Stretch="UniformToFill">
                    </Image>
                    </Border>
                </StackPanel>
            </Border>
        </DataTemplate>
    </Page.Resources> 

        

<GridView x:Name="gridView"  ItemTemplate="{StaticResource imageTemplate}"  IsItemClickEnabled="True" ItemClick="gridView_ItemClick" SelectionChanged="gridView_SelectionChanged">
            <GridView.ItemsPanel>
                <ItemsPanelTemplate>
                    <WrapGrid MaximumRowsOrColumns="3" AutomationProperties.LiveSetting="Polite"/>
                </ItemsPanelTemplate>
            </GridView.ItemsPanel>
        </GridView>

______________________________________________________________________________________

 private void gridView_ItemClick(object sender, ItemClickEventArgs e)
        {
            Image clickedItem = (Image)gridView.FindName("img");
            string imgSource = clickedItem.Source.ToString();
            

        }

I tried something like this, but no luck..

So please help me with this as I am new to WPF and Windows Apps too... :)

Thanking you all in advance....
