| Attribute | Value | Description |

Data Item Properties
The following table describes the properties for data items. They should be configured at design time.
| Property | Property Type | Description |
|---|---|---|
| Description | Input | Specifies more information that a user may find helpful. |
| DisplayName | Input | Specifies the name to display in the Workflow Editor. |
| Localization | Input | Click the ellipsis button to open the Localization Configuration dialog box where you can configure the property to localize, the language to use for localization, and the text to localize. |
| Name | Input | Specifies the identifying name. The name provides a reference so that code behind, such as event handler code, can refer to a markup element during processing by a XAML processor. |
| Source | Input |
Click the ellipsis button to open the Configure a Data Source dialog box to select and configure a source for the data item. For more information, see Configure a data source item for a resource source. If you are developing a form and choose not to specify a data source, you can specify one in the workflow and pass it in. Note: If you specify a data source in the form, it acts as a default value.
Therefore, if you specify a value in the form and as input in the workflow,
the value in the workflow overrides the value in the form, and is the value
used at run time.
|
| Source Address | Input |
Specifies the fully qualified address of the data source you want to assign to the current data item. It can only be used for items with the same configuration. For example, this property can be used on all Mixer classes that have a Speed property. Note: Use this property only if you want to override the Ldap
address of the item to read what is passed in by the workflow, but retain
all other configuration details.
For example, if you configure a workflow to read data items of Line1 (configured to read propertyXYZ), you can override the source address to be Line2, and still read propertyXYZ. |
| Subscribe | Input |
Select this check box to indicate that this data item should be subscribed to. If this check box is cleared, the data item value is read only once when the form or user display loads. When this check box is selected, the data item value is updated continuously as the data item source updates. |
| Uid | Input | Specifies the unique identifier (for localization). |
