I need to add child rows dynamically to the data grid below parent row on a particular cell click. Parent row shold display aggregate of the child rows. On updation of cells in child rows parent rows should get updated and vice versa....I can not use grouping because parent cell is any between column. If one child row is present then it should come as a parent row else If multiple child rows are present then it should come below parent rows. for e.g I have list of products. Products can have one or more supplier mapped to it. Cost price is base don supplier. so if multiple suppliers are present then on click of supplier cell child rows should show list of supplier and corresponding price value and cost price aggregate should come in parent row. Please can you give me any pointer ,how to do this
