BindingList : How to cancel AddNew() RRS feed

  • Question

  • Hello,

    I have implemented a CustomBindingList that derives from BindingList.

    I need to be able to cancel the AddNew call.
    I have overrided the method but I'm not able to cancel it

    Something like this would be perfect !

    protected override object AddNewCore()
           object l_ret = null;
           if (a_test == false)
               l_ret = base.AddNewCore();
           return l_ret;

    Any idea ?
    Thanks for your help

  • Why do you want to be able to cancel an AddNew?

  • because I have two BindingLists, one local and one remote.
    The local list that is binded to a datagridview.
    When the user try to insert a new item in the local List, if I fail to insert the item remotely I want to cancel it in the local list....
