[RESOLVED] Option in ADODC or DataGrid components to update existing row?

[kutlesh]

I am using ADODC component with select query to feed the DataGrid component with data.

Everything works fine except, the thing I don't know how to update existing row instead of adding new one.
There are two columns in the datagrid which serve as keys. When i add another row with the same combination of those two key columns, the datagrid saves another row in the table.
Yes, the table should be set to have two keys, but its not, and i don't want to set keys, because its a legacy application and I might break other parts of it.

Is there some option to tell either ADODC or DataGrid component to update existing row with that same combination of keys instead of adding a new row?

Or I should add keys to my table, and explore where the application will break next?
