I am trying to update using data grid
my database table has composite key (2 columns as primary key).
lineNo and date are primary keys.
I got the datagrid to display the data
lineNo date rate crew
10 4/1/05 100 5
20 4/2/05 120 6
10 4/6/05 110 4
I want the user to be able to change date,rate and crew using data grid. (date column is the part of primary key)
