Drag-and-Drop facility in Silverlight 5

Question

Hi All,

I need help in Silverlight 5.

I want to make a Silverlight 5 Application in which the user can drag-and-drop controls.

Just like we do in Visual Studio.

I am aware that we have to user AllowDrop property. But, don't know how to go about it.

Requirements in brief -
Left-Hand side - The controls(Button, Textbox, Images, etc).
The user can click on anyone and drag it to right-hand side panel.

Please help me out !!

Thank You All In Advance !!
