jQuery Grid Plugin - jqGrid

Hi,

I searched and tried everything to get it solved but I cannot find a way to do, that's why I would really ask for your help:

I have a grid that contains a subgrid. The subgrid opens on every row in the grid (+ sign):

+ Test

    -  SubEntry1

    - SubEntry2

+ Test2

    - SubEntryB1

    - SubEntryB2

Now when I click on Add in one of the subgrids I want to pass the parent id to the controller action. Now you will say, use the event 'subGridRowExpanded', but here's the problem:

Imagine I expand both lines, 'Test' and 'Test2' and click afterwards on 'Add' in Subgrid within 'Test2'. Now you don't know which subgrid was expanded last. You can expand Test, then Test2, and open 'Add' in Test but the id of Test2 would have been saved last in subGridRowExpanded.

Is there another way? So that I can maybe find out the rowid of the +-sign? I can't imagine a solution right but maybe add a comboBox in the add-dialogue to choose one of the ids, but I assumed that this is not necessary, because I clicked one of the subgrids within the specified row.

Any help would be kindly appreciated.

thanks,
