Hi Manolo,
Sorry for the inconvenience caused. In the annotation X and Y values are object. So we cannot set X and Y values in the design page. We have to set the X and Y values for the annotation in the code behind. Please find the below code example.
In the above screenshot we have set the X and Y positions for the annotations.
We have modified the sample as per your requirement. Please find the sample from the below location.

We have logged issue report on “Giving X and Y value for the annotation in the designer page”. And we have created separate incident under your account for the better follow-up.
Please let us know if you have any concern.
Regards,
Sanjith K
