Change 24-hour format to 12-hour in Delphi 10.3 Rio

Question

How to change the format 24-hour to 12-hour in Delphi 10.3 Rio in DBGridEh field?

I am trying to find one in the property of DBGridEh but no avail. Should I have to create a code for this or an override to system utils?

Answer 1

Each column of DbGridEh has property "DisplayFormat". So you can use this property to set desired format acording his data type. For columns with datatypes TDateTime you can use :

dd.mm.yyyy hh.nn AM/PM

or

hh.nn.ss AM/PM

for example to set 12 hour format.

For more information about formatting a DateTime values see:

Edit:

As Ken White noted, you can also use TField.DisplayFormat so no matter where the content of the field is displayed, it will have the same format.
