Question

Can anyone say how I can expand and collapse treeColumn value in advancedGrid in Flex under a particular parent. I just want to expand and collapse only the children under a particular parent node in the grid. Thanks in Advance Vishnu

Answer 1

you can expand/collapse a specific item simply giving this statement to your adg:

adg.expandItem(<your_item>, !adg.isItemOpen(<your_item>))

your_item is the item of your dataProvider that you want to expand/collapse in your adg
