Gets a value that indicates whether a client application should allow users to change the value of the property.
Assembly: System.ComponentModel.DataAnnotations (in System.ComponentModel.DataAnnotations.dll)
The property indicates whether users should be allowed to change the existing value of a property. The AllowInitialValue property indicates whether users should be allowed to set a value for the property when inserting a new record. Setting either property to false does not functionally prevent the value from being edited or set to an initial value. You use this attribute to communicate to the client application how the property should be handled.
