Devexpress 18 gridcontrol 打印功能

写完以下代码点按钮没反应 是为什么？大神帮啊
private void simpleButton1_Click(object sender, EventArgs e)
{

        PrintableComponentLink link = new PrintableComponentLink(new PrintingSystem());
        link.Component = Dgv;
        link.Landscape = true;
        link.PaperKind = System.Drawing.Printing.PaperKind.A3;
        link.CreateMarginalHeaderArea += new CreateAreaEventHandler(Link_CreateMarginalHeaderArea);
        link.CreateDocument();
        link.ShowPreview();
    }
    private void Link_CreateMarginalHeaderArea(object sender, CreateAreaEventArgs e)
    {
        string title = string.Format("压力灭菌监测记录");
        PageInfoBrick brick = e.Graph.DrawPageInfo(PageInfo.None, title, Color.Black,
           new RectangleF(0, 0, 100, 21), BorderSide.None);

        brick.LineAlignment = BrickAlignment.Center;
        brick.Alignment = BrickAlignment.Center;
        brick.AutoWidth = true;
        brick.Font = new System.Drawing.Font("宋体", 11f, FontStyle.Bold);


    }

直接在开头写一个 MessageBox.Show("ok")
如果不能弹框，说明事件没有触发或者没有关联正确

我使用的是PrintSettingController控件，你参考下

PrintSettingController psc = new PrintSettingController(gridControl);
            //页眉
            psc.CreateMarginalHeaderArea += psc_CreateMarginalHeaderArea;
            psc.CreateMarginalFooterArea += psc_CreateMarginalFooterArea;
                        psc.Margins = new Margins(5, 5, 80, 40);
                        //页脚
            if (!string.IsNullOrWhiteSpace(_nursingTable.Footer))
            {
                string footer = _nursingTable.Footer.Replace("\n", "\r\n");
                psc.PrintFooter = footer;
            }
            //纸型
            if (_nursingTable.PaperKind == "A4")
                psc.PaperKind = System.Drawing.Printing.PaperKind.A4;
            else if (_nursingTable.PaperKind == "A3")
                psc.PaperKind = System.Drawing.Printing.PaperKind.A3;
            else
                psc.PaperKind = System.Drawing.Printing.PaperKind.A4;
            //横纵向
            if (_nursingTable.Landscape == (int)CommonEnum.是否状态.是)
                psc.LandScape = true;
            else
                psc.LandScape = false;
            psc.Preview();

void psc_CreateMarginalFooterArea(object sender, CreateAreaEventArgs e)
{
PageInfoBrick brick = e.Graph.DrawPageInfo(PageInfo.NumberOfTotal, "第{0}页，共{1}页", Color.Black,
new RectangleF(0, 0, 100, 21), BorderSide.None);
brick.LineAlignment = BrickAlignment.Far;
brick.Alignment = BrickAlignment.Far;
brick.AutoWidth = true;
brick.Font = new System.Drawing.Font("宋体", 9);
}

void psc_CreateMarginalHeaderArea(object sender, DevExpress.XtraPrinting.CreateAreaEventArgs e)
{
string title = _nursingTable.TableName;
if (_drawStringHeader == null)
{
_drawStringHeader = new NursingDrawStringHeader();
_drawStringHeader.Text = " 科别：" + _inPatientInfo.DeptName + " 床号：" + _inPatientInfo.BedNo + " 姓名：" + _inPatientInfo.PatientName + " 住院号：" + _inPatientInfo.InpatientNo;
_drawStringHeader.PageInfoBrickRectangleF = new RectangleF(0, 0, 100, 21);
_drawStringHeader.TextBrickRectangleF = new RectangleF(10, 40, e.Graph.ClientPageSize.Width, 30);
}
PageInfoBrick brick = e.Graph.DrawPageInfo(PageInfo.None, title, Color.Black,
_drawStringHeader.PageInfoBrickRectangleF, BorderSide.None);

        brick.LineAlignment = BrickAlignment.Center;
        brick.Alignment = BrickAlignment.Center;
        brick.AutoWidth = true;
        brick.Font = new System.Drawing.Font("黑体", 14);


        Font textFont = new System.Drawing.Font("宋体", 10);
        TextBrick textBrick = e.Graph.DrawString(_drawStringHeader.Text, Color.Black, _drawStringHeader.TextBrickRectangleF, BorderSide.None);
        textBrick.Font = textFont;
        BrickStringFormat sf = new BrickStringFormat(StringAlignment.Near);
        textBrick.StringFormat = sf;
    }
