How would one "detect a click" on an empty sub-DGrid so as to open a dialog ?
-Sub-Grid content list all Descriptions related to the Main Grid list of existing records.
... if there are no description corresponding to a specific record, than grids remains empty :
Any time this is the case,
-> I would like to let the user click on the empty blank space and popup a message offering him to create a new record

..so first, I would need to detect a click anywhere on the blank sub-grid space...is that doable ?
Or any other way.
Thanks !
