Cancel The Delete Activity From Within The Delete Click Event?
Feb 5, 2006I have a BindingNavigator and combobox tied to the same BindingSource. I want to allow the user to confirm a delete after hitting the delete button of the navigator. It appears that the row gets marked for deletion after my BindingNavigatorDeleteItem_Click event handler is processed. Is there no way to cancel the delete activity from within the delete click event? If not, then it becomes necessary to store a delete flag and catch another event to RejectChanges.

Not Allowing Null Value In Datagridview When Trying To Cancel An Edit?
Jul 28, 2010I have a datagridview that has three columns. All three fields are unique fields in the Access table that the datagridview reads from in order to make sure that an entire record is unique. I have a form where a user can add a new record. Upon opening the form, two of the three fields have data automatically entered, leaving one field for the user to enter information. The field that the user needs to enter information in is put in edit mode. The problem I am having is that I have a Cancel button if the user does not want to enter a new record and wants to close the form. I tried using the following line of code to remove the current record that has information in two of the three fields before closing the form:
PriceHistoryBindingSource.RemoveCurrent()
