Dbgrid1.Columns[x].DisplayFormat doesn't work with String types
« on: December 06, 2020, 03:25:21 am »
The title says everything.  :D

I don't know if it's intentional or not, but the MaskEdit property on DataSet's Field can do it very well.

Tested in V.2.1.0 r64158.

TColumn does not apply DisplayFormat to anything other than TNumericField and TDateTimeField. And the reason is that DisplayFormat does not exist in the FCL DB classes for any other field type.

So it's not implemented yet or never will be?

I think we've already established it does not exist right now. I'm not an FPC developer, so I would not know what they plan to do in the future.

You can always submit a "feature request" to the bug tracker... but Delphi compatibility is pretty high on their list of requirements. And it's not in the Delphi TStringField either.
