Is it possible to ask wether an object is marked for deletion?

[Wolfgang]

Hi,

If an object is accessed which is marked for deletion, telerik will throw an InvalidOperationException.

This is not bad, but... is there a way to ask if an object is marked for deletion?

I want to remove items from a list. If something else has marked the same items to be deleted, the exception and error handling seems to slow the progress down.

So is there somewhere something like an Extension method object.IsMarkedForDeletion() ? 

Best regards
Wolfgang

Hello Wolfgang, 

You can use the GetState() method provided by OpenAccessContext. It will return the state of an object which is passed as parameter to the method.

Here is a sample how to use this method:

1.Telerik.OpenAccess.ObjectState entityState = context.GetState(entity);
2.
3.if (entityState != Telerik.OpenAccess.ObjectState.Deleted)
4.{
5....
6.}

I hope that helps.

Thanks Boris,

Is it also available from Old API?

ATM I used your info and the workaround:

Telerik.OpenAccess.SPI.IExtendedObjectScope objectScope = persistentObject.ObjectScope as Telerik.OpenAccess.SPI.IExtendedObjectScope;

which could also be shortened to

if( Telerik.OpenAccess.ObjectState.Deleted == (persistentObject.ObjectScope as Telerik.OpenAccess.SPI.IExtendedObjectScope).GetState(persistentObject))

which then looks a bit irritating.

Hi Wolfgang,

  The 'GetState' method is defined on the IObjectScope. You do not need to cast it to 'IExtendedObjectScope'. Simply call 'scope.GetState(entity)'
