Remarks

This property is used to obtain the ETag of the specified entry within an OData feed and will be populated once EntryIndex is set.

This property is also used when retrieving, updating or deleting an entry. When EntryETag contains a non-empty string, an "If-None-Match" header will be sent with the entered value when QueryService is called. When DeleteEntry or UpdateEntry is called, an "If-Match" header will be sent with the entered value.

This property is not available at design time.
