In Strategy 9.x, the option "No data returned" in Project configuration is applied to all documents at project level. To hide the empty grid when running a Report Services document and no data returned in a grid, follow the steps below to achieve the goal by taking advantage of Strategy SDK 9.2.x:
Before Customization:
Documents are displayed as the image shown below:
After Customization:
The document which is specified in the SDK sample code is displayed as the image shown below:
1. In Strategy Desktop, configure “No data returned” option under Project Configuration > Report Definition > Advanced, as shown below:
2. Use the following code sample:
import com.Strategy.web.app.addons.AbstractAppAddOn;
import com.Strategy.web.app.beans.PageComponent;
import com.Strategy.web.beans.RWBean;
import com.Strategy.web.objects.rw.EnumRWUnitTypes;
import com.Strategy.web.objects.rw.RWDefinition;
import com.Strategy.web.objects.rw.RWGridGraphDef;
import com.Strategy.web.objects.rw.RWInstance;
import com.Strategy.web.objects.rw.RWUnitDef;
public class HideGrid extends AbstractAppAddOn {
String docID = "GUID of a dashboard";
public void preCollectData(PageComponent page) {
try {
RWBean rb = (RWBean) page.getChildByClass(RWBean.class);
if (!rb.getObjectID().equals(docID)) return;
RWInstance rwi = rb.getRWInstance();
rwi.setAsync(false);
rb.collectData();
RWDefinition rwd = rwi.getDefinition();
RWUnitDef[] rwUnits = rwd.findUnitsByType(EnumRWUnitTypes.RWUNIT_GRIDGRAPH);
RWUnitDef rwUnit;
RWGridGraphDef griddef;
for (int i = 0; i < rwUnits.length; i++) {
rwUnit = rwUnits[i];
griddef = (RWGridGraphDef) rwUnit;
if (griddef.getViewInstance().getGridData().getGridTotalRows() == 0) {
rwUnits.setVisible(false);
}
}
} catch (Exception ex) {
System.out.println(ex);
}
}
}
ADDITIONAL INFORMATION:
The Strategy SDK allows you to customize the standard Strategy Web interface, and extend and integrate the Strategy business intelligence functionality into other applications. However, before changing the way Strategy Web products look or behave, it is helpful to understand how the application is built. For more information regarding the Strategy Web architecture or the process of customizing Strategy Web, please refer to Strategy Developer Zone (https://community.strategy.com/topic/0TO44000000FliLGAS/sdk).
To access the Strategy Developer Zone, you must have access to the Strategy Knowledge Base, you must have purchased the Strategy SDK, and you must be current on your Strategy maintenance agreement. If you are a US-based business and believe that you satisfy all three of these conditions but you do not have access to the Strategy Developer Zone, please contact Strategy Technical Support at support@microstrategy.com or at (703) 848-8700.
