Question : Entity Framework Detecting Changes
I am currently using the entity framework as a data layer for an application. I am still learning the EF so i might have some of the nameing conventions off.
I have a context Person object that i am displaying to the user via a group of bound controls. When the user closed the form i would like to detect whether any changes have been made to the object. If there have been, then i will prompt them to save the changes.
I have everything working well, but i can't seem to figure out how to detect if the object has changed. I see that my Context Object has a .DetectChanges, but that doesn't seem to return what i would expect.
Is there a way to tell whether changes has been made to an object in the EF?
Thanks in advance.
Answer : Entity Framework Detecting Changes
Telerik OpenAccess has an IsDirty flag, but EF does not appear to have this.
However, this article shows how to implement it.
