Data (for XML Form Documents)

The Data tab page of the Properties dialog for an XML Form document offers some XML forms settings.

P'aportar a esta orde...

Open context menu of a selected control on an XML Form document, choose Control Properties - Data tab.

Open Form Controls toolbar of an XML Form document, click Control icon - Data tab.

The possible settings of the Data tab page of a control depend on the respective control. You will only see the options that are available for the current control and context. The following fields are available:

Modelu de datos XML

Select a model from the list of all models in the current document.

Enllaz

Select or enter the name of a binding. Selecting the name of an existing binding associates the binding with the form control. Entering a new name creates a new binding and associates it with the form control.

Espresión d'enllaz

Enter the DOM node to bind the control model to. Click the ... button for a dialog to enter the XPath expression.

Specifies if the item must be included on the XForm.

Click the button to open a dialog where you can enter the name of a new user-defined data type. The new data type inherits all facets from the currently selected data type.
