Visual C# | DataGridView events exercise | Write code for the UserDeletingRow event
This exercise is provided to allow potential course delegates to choose the correct Wise Owl Microsoft training course, and may not be reproduced in whole or in part in any format without the prior written consent of Wise Owl.
You can learn how to do this exercise on the relevant Wise Owl classroom training course (sadly for the moment only in the UK).
You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.
If you haven't already done so, create a data source for the Mortgage database in the above folder.
Create a form called frmApplicant, and add a DataGridView listing mortgage applicants (or you may have a version of this form already created that you could use).
Write an event-handler for the form's UserDeletingRow event so that when a user tries to delete a record, he or she sees a confirmation message:
Surely the answer to this question has to be NO?
Make sure that if a user chooses No above, the record is not deleted (ie the deletion event is cancelled).
When you've finished, close down your form.
