Focus on a specific page using a brick

Hello. I am new to c# and I am trying to fix an error in my report. I am trying to iterate through my report and search for a tag that matches the tag of the previous page that was viewed. The reason I must approach it this way is because I am adding a parameter that changes the amount of pages per record. I found the following sample code but I do not know how to use the ShowBrick method. The method should be similar to this but I do not fully understand exactly how to translate from the printingsystem level.

printingSystem1.PreviewFormEx.PrintControl.ShowBrick(brick, page);
            printingSystem1.MarkBrick(brick, page);

 private void xrReport1_BeforePrint(object sender, System.Drawing.Printing.PrintEventArgs e)
    {
        ((XRLabel)sender).Tag = this.GetCurrentColumnValue("CaseId");
    }

    private void brickcheck_PrintOnPage(object sender, PrintOnPageEventArgs e)
    {

        foreach (Page p in this.Pages)
        {
            DevExpress.XtraPrinting.Native.NestedBrickIterator iterator = new DevExpress.XtraPrinting.Native.NestedBrickIterator(p.InnerBricks);
            while (iterator.MoveNext())
            {
                VisualBrick visualBrick = iterator.CurrentBrick as VisualBrick;
                if (visualBrick != null)
                {
                                             ???? I don't know what goes here ????
                }
            }
        }
    }
