How do I drag and drop between two datagrids in wpf?

For example, dragging a row from a datagrid table to another datagrid table? However the other datagri开发者_StackOverflowd table just present the row, it manipulates the data gathered and present it in its own way.

I am using wpf toolkit. Can show me a sample example on this?

Here is a good place to start. Although the tutorial is shown for ListBox, it can also be adapted for DataGrid (although I have not tried it for myself).
