Hi Eduardo Sobrino,
Thanks for contacting Syncfusion products.
Currently WinUI SfDataGrid doesn’t have support for GridDateTimeColumn. We have logged a feature request for the this. We will include this feature in our 2021 Volume 2 main release, which is expected to be rolled out in June 2021. We will let you know once it is released with this feature.
However you can achieve your requirement by using GridTemplateColumn with our DatePicker control as EditTemplate. Please refer the below given help documentations.

Please let us know if you require further assistance from us.
