Hi Byron,
Thank you for contacting Syncfusion support.
In PropertyGrid, if you need to hide the Search box and button panel, then you can set the “SearchBoxVisibility” and “ButtonPanelVisibility” property as Collapsed to remove the space above the PropertyGrid. We have prepared a simple sample for your reference and it can be downloaded from the below location.
Please let us know, if we misunderstood your query.
Regards,
Keerthana J
