Now, I have down another grid base cursor for details - If the user hold in the top grid line2 in column orders I want to give the orders information for company DEF, if he hold in the top grid line3 in column income I want to give the income information for company GHI etc.
>Can I get it?

You may call some code from grid.afterrowcolumnchange event to collect child record to another cursor. This event code is usually triggered by some property (you may see it in existing code).
