After setting a default date inputFormat, is that possible to override it in a specific place with another input format?

[michaelqiji]

As shown in the title, I have tried ListGrid.dateInputFormat, DateRangeItem.dateInputFormat, DateItem.inputFormat, and DatetimeItem.inputFormat. I give the another inputFormat to those property, but it still using the default dateInputFormat. So my question is that is it possible to override the default one?

Yes, and the properties you talk about setting are the right way to do it. You are most likely just not setting those properties correctly, for example, trying to set one on a ListGridField instead of via ListGridField.editorProperties, or setting to a wrong value.
