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

Is there any way to know whether any item in advanced data grid is in expand or collapse state? – Vishnu Vikraman Sreekala Feb 13 '13 at 06:27

hi, i'm not sure to have understood your question. I try to answer: you colund write a boolean method which loops for each row of the dataProvider and makes this control: adg.isItemOpen(youDp.getItemAt(i)) == true....if you get all controls true this means that all items are expanded...obviously you can do the same control for the opposite case. Hope this helps...let me know! – marcocb Feb 13 '13 at 18:51

I will make it clear to you. I have an adg which have a tree structure (hierarchical). I want to know whether the item is in collapse (+) state or in expand state (-). – Vishnu Vikraman Sreekala Feb 14 '13 at 05:47

Once again thanks @marcocb. The above scenario worked for me. – Vishnu Vikraman Sreekala Feb 14 '13 at 11:04
