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):
The default values for a new row
When everything is working OK, close your form.
