Example

Executing the example requires a form with the Button1 button, the ReportBox component and the UiReport component named UiReport1, which is used as a data source for the ReportBox component. An active sheet of the regular report connected to the UiReport1 component contains a chart legend.

    Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
    Var
        Report: IPrxReport;
        Objs: ITabObjects;
        Obj: ITabObject;
        Target: IUiCommandTarget;
        Context: IUiCommandExecutionContext;
        Data: Array;
        i: Integer;
    Begin
        Report := UiReport1.Report;
        Objs := (Report.ActiveSheet As IPrxTable).TabSheet.Objects;
        //Searches legend on regular report page
        For i := 0 To Objs.Count - 1 Do
            If Objs.Item(i).ClassId = "PrxChartLegend" Then
                Obj := Objs.Item(i);
                Break
            End If;
        End For;
        If Obj <> Null Then
            Target := WinApplication.Instance.GetPluginTarget("Report");
            Context := Target.CreateExecutionContext;
            Data := New Variant[2];
            Data[0] := Report;
            Data[1] := Obj As IPrxChartLegend;
            Context.Data := Data;
            Target.Execute("ChartExternLegendSetup", Context)
        End If;
    End Sub Button1OnClick;

Clicking the button opens a standard dialog box that is used to set up parameters of the legend found on the active sheet of the regular report connected in the UiReport1 component.
