Deleting Objects

Thank you all for encouraging me.
     Actually what I have concluded is that DevForce seems more geared to WPF and Silverlight. This is undeniable. My solution is in Windows forms where even the examples are very scarce nowadays.

I will try to contact devexpress where I have a universal subscription and they respond very quickly.

Thank you all.

These forums are for the free product, and when they are busy responding to registered users it sometimes gets quiet on the 'free advice' front.

Thanks,
   I have an XtraGrid that is bound to a binding Source.
When the form loads I call something like this

var query=_manager.Contracts;
var op=query.ExecuteAsync();
op.Completed+=op_Completed;



And the op_Completed is like this

void op_Completed(object sender,EntityQueriedEventArgs<Contract> e)
{

if(e.IsCompleted)
{
     contractsBindingSource.DataSource=e.Results;
}


}

However I tried also to use List<Contract> and the same it does not work.

The Item gets geleted but the XtraGrid does not refresh and the Items just remains.

Thanks.

Hello I have been playing around with IdeaBlade and many aspects appear straight but one thing that I don't understand why it is idesigned this way is the caching process.

I have a Contract table that has contract items as a mater detail relationship.

I have a form that displays a list of contracts in XtraGrid bound to bindingsource. When I try to delete a contract it gets deleted in the database but the list on the grid stays as it is. it is not updated. If I try to call contractBindingSource.ResetItems(false) I get an exception that the list is readonly.

The contractBindingSource.RemoveCurrent either does not work it gives an error.
So how can my Grid be in Sync with the EntityManager or how can I disable this caching stuff. I feel very frustrated coz I've tried every option I know.


This is what I do.

Contract _contract=contractBindingSource.Current as Contract;
_contract.EntityAspect.Delete();
//contractBindingSource.RemoveCurrent() raises an error
//_manager.RemoveEntity(_contract,true) has no effect
//contractBindingSource.ResetItems(false) raises error
_manager.SaveChanges();
_manager.AcceptChanges();

Now how can I refresh my cache?
Please If any one can help.
Thanks in advance.
