Gets or sets a string the WebLoader uses to uniquely indentify a data source (business class) instance.

Property Value

The unique identifier, or an empty string when none has been assigned.

Remarks

The DataUniqueID can be used as a parameter of an IWebLoaderEvent.

Example

The following example demonstrates how to serialize an IForm and assign a DataUniqueID.
