Hi Tho jun,
Thank you for contacting Syncfusion Support.
“Query #: how can I display array in PropertyGrid?”
Property grid control doesn’t have support to display array. So we suggest you to use CollectionObject which contains Key Value Pairs as Properties in the PropertyGrid to display array.
Please download the sample from the below link
