I want to map rows of two datagrids, the mapping should be
done on user mouse drag from source datagrid row to target datagrid
row by drawing an arrow. Also if user want to delete the relation
by removing the arrow drawn.
There would be number of rows in both the datagrids and user
should be able to map one to one , one to many etc.
Is it possible, then please reply Also if any alternative is
there suggest it.
