Before you can do this exercise, you'll need to download and unzip this file (if you have any problems doing this, click here for help).

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.

Create a data source for the Mortgage database in the above folder, to include all tables.

Create a new form called frmPerson, and add a DataGridView to it to show a list of mortgage applicants.

Customise this DataGridView so that:

  • Any loan amount of £100,000 or more shows up in pink (clue: use the CellFormatting event)
  • It is impossible to add any new records to the table (set the AllowUserToAddRows property)

Your final DataGridView should look like this:

You can't add rows, and big loans appear in pink

Now amend your DataGridView so that it is possible to add new records, but that the default values for them are a mortgage with amount £0 and mortgage type 1:

When you click in a new row, the default values appear

Use the DefaultValuesNeeded event.

Close down any forms that you have open.
