Data Grid Drag & Drop

I have a form with two data grids on it. Each grid is connected to a seperate database table. I want the user to be able to select a row in the first datagrid and drag and drop it to the other datagrid, thus adding the whole record to the second grid and table.

If anyone knows how this can be done or has an example of something similar, please email me at ToRRocK@aol.com
