If you are using class MM .NET entities, there needs to be an IgnoreNavigation = true inserted into the call path of the DeleteEntity to prevent the display of the Save Changes dialog (mmBusinessUIHelper.DeleteEntity) This only occurs with business objects that are using the datatable or dataviews.

After following the instructions in this section to associated a business object with the button, then there is one other step you need to take.

Thanks, that helps a little bit more, however I am still getting prompted if to save changes.

Here is what I did:

I bound the Delete button to "CourierAirWayBill" (interesting that I didn't have an ellipsis button to display the selection dialog as described in the help file).

I added this code in:

        public override bool DeleteEntity(mmBusinessObject businessObject, mmBusinessEntity entity)
        {
            this.IgnoreNavigation = true;
            bool result = base.DeleteEntity(businessObject, entity);
            this.IgnoreNavigation = false;
            return result;
        }

If I run my screen, search for some records, select one and then click Delete, I get prompted if to delete, I say yes and the row disappears from my grid which displays the results of my initial search.

If then run a search again, or move onto a different row in the grid, I get prompted: "Do you want to save changes?"

Is there somewhere else that the IgnoreNavigation needs to be set too?
