    Hi sudhir,

    I am sorry for the caused inconvenience.

    We do not allow setting the Source property of a routed event anymore as this was one of the changes in the WPF SP and we decided to make the change in our routed events as well.

    This has broken the example. Thank you for pointing this out. I  fixed the example and I updated the Code Library project.

    If you want, you can have a look at this example with a ListBox that also supports rearrange:

    Hopefully this will work in your case.

    Best wishes,
