Hi Samir,
Thank you contacting Syncfusion support.
We have checked reported query “DataForm cannot be modified like SfTextInputLayout” and we considered and logged a feature SfTextInputLayout in DataForm. Currently, we are implementing the same, we will include this new feature in our upcoming Volume 2 main release which is expected to be available by end of June 2019. We appreciate your patience until then.
Regards,
Subburaj Pandian V
