User interface considerations

[cpmasesa]

Hello ALL,

i have made a database app and want to improve the functionality of the user interface.

In 'edit' forms i used TDBEdit. I want to change color of an edit control IIF that field has been changed by the user (edited). How can i do this?? I cannot find an AfterEdit event on TField.

In 'browser' forms data is displayed in a TDBGrid. Two of the fields are Lookup fields so there is a dropdown box in the grid for these fields.

I want when user types 'C' the drop down opens and moves to 1st entry starting with 'C' (if it is there). Again how can i do this??

Maybe there are freeware/shareware somponents that can do this stuff??

TIA

Make a global variable on your form and use the TDBEdits onenter and onexit events to see if they have changed.

var
Changed : String;

procedure TForm1.Enter(Sender: TObject);
begin
Changed := TDBEdit(Sender).Text;
end;

procedure TForm1.Enter(Sender: TObject);
begin
if TDBEdit.Text = Changed then TDBEdit(Sender).Color := clWhite else TDBEdit(Sender).Color := clAqua;
end;

Then just add the "Enter" procedure to the onenter event of your TDBEdits and vice versa for the onexit

The second procedure should be TForm1.Exit(Sender: TObject);

Whos says cutting and pasting your text saves time!

If you drop a TComboBox component on your form and set its' 'AutoComplete' property to 'True' then it should perform this functionality. Check out the Delphi help.

I think autocomplete is only present on Delphi 6 and above (could be wrong), so if it isnt there, there are plenty of free third party components which can do this for you.

EricDraven: (TheCrow??!!)

Thanks, it worked like a dream!! have to modify it so it will work for other controls eg dbcombo, dblookupcombo, etc

StrectchWickster:

I want the behaviour in a GridColumn not a plain combobox.

Can you suggest a freeware/shareware dbgrid that does this AND displays Boolean fields with a check mark if true??

TIA
