Null Value In DateTmePicker

Hey all,

How do I display no values in the DateTimePicker when the user hasn't entered/selected a date?

When I bring up a new entry screen, all the DateTimePicker dates show the date the component was placed on the form. I don't want it to show anything unless data has been entered.

Thanks,
Chad

it's protected method for the TDateTimePicker
Prss Control while u move the move above TDateTimePicker, so when u see it in blue color, click on it, and u will see the source of that control, here's some source of the ComCtrls.pas, that contain all the declartion of TDateTimePicker class

 TDateTimePicker = class(TCommonCalendar)
  private
    FCalAlignment: TDTCalAlignment;
    FChanging: Boolean;
    FChecked: Boolean;
..
..
  protected
    procedure CheckEmptyDate; override;
    procedure CreateParams(var Params: TCreateParams); override;
    procedure CreateWnd; override;
    procedure Change; dynamic;
..

Best regards

Hi Mohammed,

I'm using Delphi 6....and I did what you said in the designer on my form with the TDateTimePicker and I didn't see what you where talking about.

How would I write the code to override CheckEmptyDate method to not display the date unless there was a value entered by the user or read from a record?

Thanks,
Chad
