Hi sarath.satheesh,
I seems that Drag/drop between controls is not supported in Metro-style applications at this time. However, it is said that there is one customer who can drag and drop from one GridView to another GridView in a C# XAML Metro App. You can refer
to this thread for more information about the drag/drop items:

What's more, this documentation talks about guidelines and checklist for drag-and-drop animations in Metro style apps. I suggest you refer to it for more helpful ideas:

I hope this reply is helpful to you. If you have any questions, please feel free to let me know.
Best regards,
