Drag and drop image from scrollviewer to grid.

Hi there.

Im developing an metro app in C# and XAML.

Basically I have images in a scroll viewer, I have a drag and drop function working fine, what I want to happen is the user can drag the images and place it in another box. The the image then aligns itself to the left of the box.

I cant think of how I would go about this as I am rather a novice at C#.

Thanks in advance
