# Data (for XML Form Documents)

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

To access this command...

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:

## ຮູບແບບຂໍ້ມູນ XML

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

## ການຜູກມັດ

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.

## ສະແດງການຜູກມັດ

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

## ຕ້ອງການ

Specifies if the item must be included on the XForm.

## ກ່ຽວຂ້ອງ

Declares the item as relevant.

## ອ່ານໄດ້ຢ່າງດຽວ

Declares the item as read-only.

## ຂໍ້ຈຳກັດ

Declares the item as a constraint.

## ຄິດໄລ່

Declares that the item is calculated.

## ຊະນິດຂໍ້ມູນ

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.

### ຊ່ອງວ່າງ
