Applications Grid / Reports
#1

Hello,
I created a nested grid in my gridview.
There ist always the plus Image closed and the user has to open each row to see the detail.

Is there a makro or other opportunity to change it, that all rows are detailed open when first load the page?

Thanks for help.

If you need to have all items open I would recommend to disable treeview. You won’t be able to close it, but I think that wouldn’t be a problem then?
