Edit and Display Mask

Recommended Posts

Hi,

 

Within my apps i use MyDac components voor database access and so

also the query components.

 

The query components contains the fields and is use 2 time fields

On a field it's possible to set the DisplayMask (HH:mm) for time

and EditMask (99:99)

 

Then i use the OnSetText event for this field with the following code:

 

procedure TdmArtist.ArtistStageTimeStartSetText(Sender: TField;
 const Text: string);
begin
 if trim(Text)=':' then
   Sender.Clear
 else
 try
   Sender.AsDateTime:=StrTotime(Text);
 except
   // custom message when the time is invalid
   raise exception.Create('"'+text+'" is not a valid time or time format!');
 end;
end;

 

Normally on standard Delphi applications it works. With uniGui i dont get

the display/edit mask on a uniDBEdit component.

 

How can i create a edit mask for time and check if it's a

valid entered time.

 

Regards Peter
