A Linked DataLayer allows a DataLayer to be re-used, either from the current report page, or the previous page.
To reuse a DataLayer in the same report definition, add a child Data Layer Link element and give it an ID. Then create a DataLayer.Linked element, setting Linked DataLayerID to the same ID.
To reuse a DataLayer from the calling report definition, set the report Target's LinkDataLayers attribute to "True". Then use a DataLayer.Linked element, setting Linked DataLayerID to ID of the the original DataLayer.
This also works for charts, so that a chart on the current page re-uses a DataLayer that's on the same page. Use a DataLayer.Linked under the Chart element, setting the Linked DataLayerID to the ID of another DataLayer in the same report definition. |
