RxDBGrid filter problem
«

February 07, 2016, 12:05:21 pm »
I use RxDBGrid.
My quickfilter is set in one column.
How to refer to the visible rows?
Dataset always contains all rows.
RxDBGrid does not filter dataset.
RxDBGrid creates a virtual dataset?
How filters rxdbgrid?

Use ZEOS or SQLDB DB components for acces to you SQL data. In this components property Filter work fine. Also TDbf component filtred data from DBF files.
RxDBGrid's filter dialog work with this property.

I'm sorry, for digging up the old topic.
How does the quickfilter work?
Quickfilter probably does not use property "filter"?
