Dinamic hierarchical GDBG

[Ivan]

Hello,
I am trying to build a GDBG with a hierarchy inside. I need to load the data when the user clicks on the + item avoiding to load all the data at the beginning.
Are there any event that is thrown when the user clicks on the + item?

Could you guide me in this task, please?

Thanks in advance.

The grid.RowExpanding event is raised right before the row is expanded. But I think you woul dhave to set up all the relations initially, and just leave the child tables empty. Then in RowExpanding, you would try to dynamically populate the the child with the proper rows. If you need it, I can try to do a sample later today or tomorrow. This may not be doable.
