How to add data of rows of one editable grid to the database table for the same columns of another editable grid.

I want to copy rows of one editable grid to the database table for the another grid:

Editable Grid1: abc (columns: column1, column2, mDate, column4,column5)

Editable Grid2: xyz (columns: column1, column2, mDate, column4,column5)

I want to copy values of columns(all rows) of editable grid1 to the database table for different mDate selected for editable grid2.
