When I use a getDatePicker as editor, when the user starts typing a date, without pressing ENTER before, the first number he types is "eaten", month 1/1900 is used, and then typing is ok after the second digit. Sometimes it uses 1/1900, sometimes it uses 12/1899. Original date month/year are lost.
If he presses ENTER at the cell before typing the desired date, everything works well.
Original date month/year are preserved when you start typing the day after having pressed ENTER before.
Please use your demo, tms.fnc.uipack\Demos\VCL\DataGrid\Basic\Editing .
The original date of the first row was 25/6/2025. I type "14", and this is what I get.
