Gets a IWebLoaderEvent value for use in the WebLoader component.

Property Value

An IWebLoaderEvent.

Remarks

This property is only used with the WebLoader. If an external JavaScript function assigns a new value to DataUniqueID, the WebLoader calls the specified web service to retrieve the data source (business class) values corresponding to the DataUniqueID value.

Example

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

using suite4.net.FormDatabase;
using suite4.net.Sample;
