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.

If you haven't already done so, create a data source for the Access Mortgage database in the above folder.

Create a form called frmPerson to show a list of mortgage applicants in a DataGridView, then customise this DataGridView so that:

  • Any loan amount of £100,000 or more shows up in pink (use the CellFormatting event)
  • You cna't any new records to the table (set the AllowUserToAddRows property)

This is what your DataGridView should look like:

As promised, the largest loans appear coloured

Change your DataGridView so that you can use it to add new records, but if you do the mortgage type default value is 1 and the loan amount default value is 0 (use the DefaultValuesNeeded event):

When everything is working OK, close your form.
