Hi Alessandro,
Thank you for contacting Syncfusion Support.
Query#1:" Is there a way to hide some of my class' properties from being displayed in the PropertyGrid?"
Yes, In our PropertyGrid the particular property can be hide by using "HidePropertiesCollection". Please refer the below KB to hide the property in PropertyGrid.

We have created a sample with "ReadOnly" attribute. In tihs sample we have hide the property "Name" and we have used ReadOnly property for "Area" and "Mobile".
Please download the sample from below.
