When I click on the "AddNewItem" button on the BindingNavigator the record count number increases but it does not display "new" blank controls.
The problem seems to be with checkboxes that are bound to a datasource on the form.
cbActive.DataBindings.Add("Checked", BindingSource1, "Active")
If I comment this out then the "AddNewItem" works as expected.
I have tried swapping the code for:
cbActive.DataBindings.Add("CheckState", BindingSource1, "Active", True, DataSourceUpdateMode.OnValidation, CheckState.Unchecked)
But this causes invalid NULL issues when I save the data.
