I have searched the forum for this issue without success and your online example is too simiplistic to adapt.
I have 4 grids on a page, each representing a separate db table, and the schema for each table is different. I need to drag rows from 3 of the grids to the 4th to form new records aggregating the data from the 3 source tables. I know how to capture the contents of the 4th grid and to update the db. My problem is getting the rows from each of the 3 source grids to stick to the 4th grid.

RadGrid_3 -----------
Can this even be done? If so, is there a reference implementation somewhere?
