Thanks for using Syncfusion products.
We have checked the reported requirement related with PropertyGrid. By default, in PropertyGrid control the editor size will be adjusted according to the property we have used. So we are afraid that we understood your requirement wrongly. Can you please let us know which type of property that you are using and also let us know whether you have customize any type of editor in PropertyGrid control. It would be helpful for us to proceed on this further.
Let us know whether this helps also if you need any further assistance on this.
