# Data (for XML Form Documents)

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

للوصول لهذا الأمر...

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:

## نموذج بيانات XML

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

## ربط

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.

## تعبير الربط

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

## مطلوب

Specifies if the item must be included on the XForm.

## ذو صلة

Declares the item as relevant.

## للقراءة فقط

Declares the item as read-only.

## التقييد

Declares the item as a constraint.

## العملية الحسابية

Declares that the item is calculated.

## نوع البيانات

Select a data type which the control should be validated against.

### x

Select a user-defined data type and click the button to delete the user-defined data type.

### +

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.

The following lists all facets that are valid for data types. Some facets are only available for some data types.
