Hello,
Am having a problem with updating my underlying business object from my win form grid. I have a class and a collection that implements IBindingList. The class contains a line item collection which is bound to the grid(component one grid). When I enter a new record the object gets the values without any problem and the record is saved. However fetching the same record and editing it, the properties of my object are not updated. I am wondering what it is am doing wrong. below is the code for the classes and collections and form load code. I will really appreciate any help from anyone because at the moment am confused since I thought that by implementing the IBindingList interface the two way update, form to object and object to form, is taken care of.
