JAVIERTB Please read this.

Hello 'Javiertb',  Recently you replied to my question concerning how to handle an EConvert error from a TDateField, preferrably at the component level. I just want a simple way to clear the date field to '' on entry of an invalid date. Thank you for your reply but unfortunately it was erased by the Experts Exchange before I could read it, can you reply again please?

No problem, here you go:

You have to use the Fields Editor to access the TDateField events and then the code for the OnSetText is the following:

  // TDateField is Date1 and it has an edit mask !99/99/9999;1;_

  procedure TForm1.Table1Date1SetText(Sender: TField;
                                      const Text: string);
  begin
     try
          Table1Date1.AsDateTime:=StrtoDate(text);
     except

        // if date is left blank, don't show error message
        if (text<>' / / ') then
              ShowMessage('Date Error');

        // leave a blank date when error raised
        Table1Date1.AsString:='';
      end;
  end;
