Report > Report Assembly Interfaces > IPrxControl > IPrxControl.ControlledBy
ControlledBy: IMetabaseObjectParam;
The ControlledBy property determines a controlling parameter of the regular report.
Executing the example requires that the repository contains a regular report with the REPORT identifier. Controls and parameters are added in the report.
Add links to the Metabase, Report system assemblies.
Sub UserProc;
Var
MB: IMetabase;
Report: IPrxReport;
Contrls: IPrxControls;
Contrl: IPrxControl;
Begin
// Get repository
Mb := MetabaseClass.Active;
// Get report
Report := MB.ItemById("REPORT").Edit As IPrxReport;
// Get collection of report controls
Contrls := Report.Controls;
// Get control
Contrl := Contrls.Item(0);
// Set controlling parameter
Contrl.ControlledBy := Report.MetabaseObject.Params.Item(0);
// Save report
(Report As IMetabaseObject).Save;
End Sub UserProc;
After executing the example the first parameter is set as a controlling one for the first control.
