Tildel datakilder

Felterne du har indsat har endnu ikke fået tildelt en datakilde, så de kan ikke vise nogen information fra databasen. Du bruger fanebladet (Datakilde) i feltetEgenskabseditor til at tildele datakilder.

Det allerførste skridt er at angive formularens datakilde, dvs. hvor de viste data skal hentes fra. Som tidligere nævnt skal vi bruge tabellen personer som datakilde til den nye formular.

1. Klik i selve formularen, da det er dens egenskaber du vil ændre.
2. Gå til fanebladet (Datakilde) og skriv personer i tekstfeltet Formularens datakilde eller vælg dette navn i den tilhørende drop-ned-liste.

Du har således angivet formularens datakilde. Nu skal du angive datakilder til kontrollerne.

1. Klik på det første tekstfelt øverst på formularen.
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 toolbar button. 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 Data toolbar button. Unless you made a mistake while entering data sources, you should see the 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 the little black icon with a white cross at the right in the Widget's data source box.

• 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.
