Question

Is there a way to drag and drop an image in a Windows 8 metro app.
I’m using C# and XAML.
Following is what I need…

Sure there is. You’ll have to control it yourself, but it is pretty easy. You need to use a few pointer events like this:

XAML:

<Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}"   PointerMoved="GridPointerMoved">
    <Image x:Name="image1" HorizontalAlignment="Left" Height="100" VerticalAlignment="Top" Width="100" Source="Assets/imageFile.png"  PointerPressed="ImagePointerPressed" PointerReleased="ImagePointerReleased"/>
</Grid>

Then in your CS file:

Point positionWithinImage;
private void ImagePointerPressed(object sender, PointerRoutedEventArgs e)
{
    Debug.WriteLine("Pressed");
    holding = true;

    positionWithinImage = e.GetCurrentPoint(sender as Image).Position;
}

private void ImagePointerReleased(object sender, PointerRoutedEventArgs e)
{
    Debug.WriteLine("Released");
    holding = false;
}

bool holding = false;

private void GridPointerMoved(object sender, PointerRoutedEventArgs e)
{
    if (holding)
    {
        var pos = e.GetCurrentPoint(image1.Parent as Grid).Position;
        image1.Margin = new Thickness(pos.X - this.positionWithinImage.X, pos.Y - this.positionWithinImage.Y, 0, 0);
    }
}
