Utility Network Delete Assembly with Associations

JimmyBowden

I'm trying to delete the selected features in a map some of which are Utility Network Assemblies with Associations.  When I execute my edit operation this error message is returned " The feature participates in a utility network and has existing association records that must be removed prior to deleting the feature."

Which seems simple enough, I need to delete the associations before trying to delete the assembly.  Unfortunately I have no idea how to do that.  I've looked at the sdk documentation and samples, I'm not seeing away to access associations starting from an oid and map member.  I hope I'm missing something obvious.  I would appreciate any ideas?

var ss = MapView.Active.Map.GetSelection();
EditOperation editOp = new EditOperation();
foreach (var item in ss)
{    
    foreach (var oiditem in item.Value)
    {
        //How to get/delete associations for this oid?
        editOp.Delete(item.Key, oiditem);
    }
} 
editOp.Execute()

Hi Jimmy,

You create an `AssociationDescription` object, and pass that to the `EditOperation.Delete` overload that takes one. The association description object describes an association to delete (or create, in other workflows)

For your code above:

AssociationDescription associationToDelete = new AssociationDescription(a.Type, new RowHandle(a.FromElement, un), new RowHandle(a.ToElement, un);

ediOp.Delete(associationToDelete);
