I've build a base user control, BaseViewControl, it has a dataGridView and a bindingSource on it. Both have protected access modifiers. The dataViewGrids dataSource points to the base forms bindingSource.
Then I created an InheritedUserControl, ApplicationUserView, when prompted I pointed it to my UI assembly. It inherited some other arb UserControl in the same assembly so I manually changed it to inherit my BaseViewControl.
On the ApplicationUserView's bindingSource, I set the dataSource property to my ApplicationUser domain object. The dataGridView then proceeded to populate its columns with the properties in my ApplicationUser domain class in the DesignView, as expected.
Now, in an async callback from my controller object, where the view receives an IList<ApplicationUser>, i set my bindingSource.DataSource = applicationUserList.
I've confirmed that the callback gets called and that the applicationUserList has items in it, but at run time, the grid doesn't show any rows. I suspect it has something to do with the visual inheritance aspect of it all.
I've seen VS create copies of items from inherited forms onto the inheriting form as soon as you try and modify a property of an inherited item before, which has a similar effect, but this is not the case.
Any ideas what I'm doing wrong?
Thanks, HS
