Visual C# | Complex DataGridViews exercise | Linked DataGridView and DetailsView
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.
The answer to the exercise will be included and explained if you attend the relevant Wise Owl course (sadly, only in the UK for now).

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.
The folder above contains an Access database called Films. Create a data source for this (there are 3 main tables: categories of film, certificates and the films themselves).
Create a form called frmList to contain a combobox and DataGridView. When you choose a category and certificate at the top of the form, the DataGridView should show only the films for this combination of criteria:
There are two films in the ACTION category with certificate 12
Create another form showing a single film at a time:
When you save your changes, the previous list form should reappear, to reflect any changes made
If you haven't already done so, add the necessary code so that:
- when you double-click on a film in the list (or click on the Edit button) the film automatically appears in the separate single-record form
- when you make any changes they are automatically written to the underlying database
If you've got any spare time, you could always add menus, toolbars and short-cut keys allowing a user to your forms ...
