The fields you have inserted on the Form have no data source assigned and are not yet able to display information from the database. To assign a data source we will use the (Data Source) tab of the Property Editor pane.
The very first step is to specify the data source for the Form as a whole. i.e. the location from where all of the displayed data will be fetched. As mentioned above, you will use the Persons table as the data source for the new form.
You have assigned the form's data source. The next step is to specify each widget's data source.
You can now save the form's design (this is not mandatory to test the form in action, but is recommended). To save, click the toolbarbutton. Upon saving you will be asked to enter the form's name. Enter Persons as caption and click the button. The form's name will be filled in automatically.
This is the right moment for testing your form. Click thetoolbar button. Unless you made a mistake while entering the data sources, you should see the form's fields filled with data from the Persons table.
