Topic: Message dialog for disabled field?

Is it possible to add a message pop-up for disabled field? If so how?

procedure Form1_Edit1_OnClick (Sender: string; var Cancel: boolean);
begin
ShowMessage ('Custom message ....');
end;

i dont understand your purpose, why you need to pop-up the message. Try this.
procedure Form1_Edit1_OnClick (Sender: string; var Cancel: boolean);
begin
if Form1.Edit1.Enabled = False then ShowMessage ('Custom message ....');
end;

Thanks a lot for your kind help.....
I was trying to avaoid writing code for each field in the groupbox hence in actual project groupbox contains many fields. That's the main reason for looking a solution as stated on post #1, if there is one.

Re: Message dialog for disabled field?

Adam,
There's not a whole lot you can do with disabled components when it involves events. You could use popup hints but all the components would need to be set to ReadOnly and not disabled. Groupboxes cannot be set to Readonly. Each field would need to be set to Readonly. Since you said that your project would contain a lot of fields, it may not be feasible to do it this way. The closest I could come up with to do what you are looking for is attached. The combobox needs to be the first field to have focus on the form.

Hi EHW,

Your approach comes quite close to original objective.
Thank you very much..............


I know, what I was trying to do against the logic. I thought there may be a trick.
