You probably also want to have it do the search when anyone types any character (any change to the edit box). And do both at the same time. So I could type "coke" and the list would be showing the results narrow as I do. I'd keep the text too - clearing it means I have to retype, but you could have a "clear" button to do that if it will be necessary. -- Matthew Jones |

I agree with you about the prices Given that I don't use EWB I may be being a complete moron here but I recommend that rather than responding to every edit change you have a timer linked to changes (I use the key up/down to cope with backspace etc) in the edit box an respond to the value of the edit box in there. DoFind.Interval is set to 150 which is short enough not to annoy and long enough to allow typing In Delphispeak procedure TCompaniesForm.FinderKeyDown(Sender: TObject; var Key: Word; Shift: TShiftState); begin DoFind.Enabled := False; end; procedure TCompaniesForm.FinderKeyUp(Sender: TObject; var Key: Word; Shift: TShiftState); begin DoFind.Enabled := True; end; procedure TCompaniesForm.DoFindTimer(Sender: TObject); begin DoFind.Enabled := False; if (Finder.Text <> '') and (Finder.Text[1] <> '=') then Companies.Locate('_Name', Finder.Text, [loCaseInsensitive, loPartialKey]) else Companies.Locate('_ID', StrToIntDef(Copy(Finder.Text, 2, MaxInt), -1), []); end; This one just does a locate, and is the first example I found. For filtering I use a slightly different strategy. Dump the KeyDown event, have a global string variable that's set in the timer event after setting the filter, and checked against the edit.text to see if the filter needs refreshing in the first place.

>Now you're just getting fancy! 8-) Nah - just copying those better than me. My "refinement" was to use keyup/down rather than keypress Roy |
