    Assigning data sources

    The fields you inserted have no data source assigned yet, so these are not able to display information from the database. To assign data source, use the Data Source tab of the Property pane.

    The very first step is to specify the form's data source, i.e. a place the displayed data will be fetched from. As mentioned above, you will use table persons as a data source for your new form.

    1. Click on the form's surface, as you will alter its properties.
    2. Switch to the Data Source tab and enter persons table name in the Form's data source drop down list. Alternatively, you can select this name from the drop down list.

    You have assigned form's data source. Now you need to do specify widget's data source.

    1. Click the first text field widget at the top of the form.
    2. In the Data Source tab of the property pane enter field name name in the Widget's data source drop down list. Alternatively, you can select this name from the drop down list.
    3. Click on next text field widget and enter surname as the data source.
    4. Enter data sources for street, house_number and city text fields in a similar way.

    You can now save the form's design (this is not mandatory to test the form in action). To save, click the Save object changes toolbar button or use the File-> Save (Ctrl+S) menu command. Upon saving you will be asked for entering the form's name. Enter Persons as caption and click the OK button. The form's name will be filled automatically.

    This is the right moment for testing your form. Click the Switch to data view toolbar button. Unless you made a mistake while entering data sources, you should see form's fields filled with data from the persons table.

    Note

    * If you want to remove widget's data source assignment for a form widget, you can use Clear widget's data source button near the Widet's data source drop down list. Similarly, you can use the Clear form's data source button near the Form's data source drop down list.
    • Use the Go to selected form's data source button to select appropriate table or query in the Project Navigator, so you can quickly open a table or query being the data source of the form.
