Hello,
I´ve been trying to create a plugin that triggers an event on add products on opportunity subgrid that change the discount and final price.
I tried with the "Create" opportunityproduct message, but when i add any product, error message is displayed "ISV code aborthe the operation". If i change the plugin message by "CalculatePrice" the plugin works fine but only when i change quantity or sales price in the subgrid, but a disadvantge of this is that if user only wants one piece of a product the event of calculate price never throws.
Could you told me what i am doing wrong, please?
I've been using the Visual Studio developer toolkit and the two C# classes are:
