propertygrid change done by use save in database

Propertygrid is used to change properties of cotrol at runtime like textbox combo or other control,
I want user change property of control and next time user open the form control are load as per user settings

For Example

I design a form to create Sale Invoice, default date is current date in form textbox is enable so user can change date


now,

He want that he should enable or disable textbox of date

Because when the owner create sale invoice it can change but if dataentry operator create invoice he cant change date
