|Post subject:||Capturing empty data event (dbgrid)|
Hi! i am trying a dbgrideh, with sortlocal, stfilter in false, and search panel, linked to a unidac query about a table in postgresql.
When i search data and get an empty result set, the emptydatainfo is active and displayed well.
But, i want to disable some buttons on the parent form either.
What is more, the dlbclick event is capture, dispite there is no data (dblclick gives me access to modify a record in a subform, and it get de data of the last selected record, but there is no data in sight).
I try to reach the event of empty data at searchpanel.onsearcheditchange, but it occurs before the "filter" is applied. So i do not see an empty set at that moment.
Is there a event such as after search impact? or a property to check that value, that gives me the possibilitiy of locking dbgrideh to prevent dlbclick event if there is no data displayed?
Thanks you all!
