Thank you for the update.
We have analyzed the reported issue “The Display attributes in DataForm doesn’t work as expected” and you have used the System.ComponentModel.DataAnnotation assembly to get the Display attributes which doesn’t work with DataForm. We have implemented these attributes with DataForm control itself, hence you need to refer the Syncfusion.SfDataForm.XForm assembly to use the Display attributes in DataForm.
We have prepared a sample based on the shared code snippet,
Kindly refer our UG documentation for more information about the Display attributes in DataForm, by referring the following link,
We hope that this helps. Kindly revert us if you have any concern.
