Getting an Object State
Sometimes it can be useful to find exactly what is the state of a given entity. The OpenAccessContext class exposes the GetState method, which returns the state of a persistent object.
using ( FluentModel dbContext = new FluentModel() )
{
Car newCar = dbContext.Cars.FirstOrDefault();
newCar.Make = "NewMake";
Telerik.OpenAccess.ObjectState state = dbContext.GetState( newCar );
}
Using dbContext As New FluentModel()
Dim newCar As Car = dbContext.Cars.FirstOrDefault()
newCar.Make = "NewMake"
Dim state As Telerik.OpenAccess.ObjectState = dbContext.GetState(newCar)
End Using
The ObjectState result can have the following values:
- Clean - the property is not modified.
- Dirty - the property is modified.
- NotLoaded - the property is not loaded from the database.
- New - when you initialize a new instance and add it to the context, all properties are in state New.
- Deleted - when you pass an existing category to the Delete method of the context, all properties are in state Deleted.
- Detached - the object is detached from the context.
