'Selected' value in filter combobox 13 Nov 2011 14:18 #486

My database contains several thousand entries and I have several filters which break the table into much smaller selections. When I show the initial collection it often times out as it tries to show every line. I would like to set the 'Selected' value on the filter combo to the first item in the list and prevent the default null value from being selected.

Is there an option to do this? (in the class for the combobox perhaps, I looked but couldn't find it)

A suggestion for the future - If the 'Null value label' for the combo box in a filter is set to 0 (zero) then fill the combo box with values but remove the show all value at the top of the list. Or better still have a check box to to do this perhaps.
Without this I think people will wonder why their component no longer works when their database grows. Mine has 4,500 records and without the filter I just get a blank screen.
Thanks

I found "cook" two days ago. Played around with it for a day and then within a day got rid of two legacy applications in IBM Lotus Domino Notes and replaced them with "cook". It was really easy. A piece of cake. Actually it was even easier than cooking. Cooking involves more work than developing with "cook". What can I say about "cook"? Great application great price for what it delivers great forum with a lot of information and fast responses active and friendly community fast forward moving development cycle So what should I say "Monsieur Le Cook"? Keep the good work going it will lead to success. Having become a paying member in the words of Edith Piaf may I say ..... non rien de rien ... je ne regrette rien. Vive La France.
