Equivalent of e.ReturnValue in EntityDataSource

Question

I'm using EntityDataSource with DetailsView in my ASP.NET application. I want to get identity column value after inserting the record. ObjectDataSource has e.ReturnValue property I want to know its equivalent in EntityDataSource?

Answer 1

You can subscribe to the Inserted event, which is an EventHandler<EntityDataSourceChangedEventArgs>.

The EntityDataSourceChangedEventArgs instance has an Entity property, representing the newly inserted entity.

void EntityDataSource1_Inserted(object sender, EntityDataSourceChangedEventArgs e) {
    YourEntityType newlyAdded = (YourEntityType)e.Entity;
    int newId = newlyAdded.Id;
}
