概述：本文主要講解在Stimulsoft中Designer保存和加載報表。

此示例顯示如何在報表頁面上放置水印，頁面上的水印可以是文本，表達的結果或圖像。水印也可以放在頁面的任何位置。在此示例中，我們將添加文本水印。為此，我們使用報表的繪圖頁面事件：

static void Main() 
{
    StiPage.PagePainting += new StiPagePaintEventHandler(OnPagePainting);
    StiPage.PagePainted += new StiPagePaintEventHandler(OnPagePainted);
 
    Application.EnableVisualStyles();
    Application.Run(new Form1());
}
 
private static void OnPagePainting(StiPage sender, StiPagePaintEventArgs e)
{
    if (copyrightPosition == Position.Behind)
    {
        StiPage page = sender as StiPage;
        DrawCopyright(page, e);
    }
}
 
private static void OnPagePainted(StiPage sender, StiPagePaintEventArgs e)
{
    if (copyrightPosition == Position.Front)
    {
        StiPage page = sender as StiPage;
        DrawCopyright(page, e);
    }
}

渲染水印的方法如下：

private static void DrawCopyright(StiPage page, StiPagePaintEventArgs e)
{
    if (e.IsPrinting && (!printer))return;
    if (e.IsDesigning && (!designer))return;
    if ((!e.IsDesigning) && (!e.IsPrinting) && (!preview))return;
 
    Rectangle rect = e.FullRectangle;
    if (rectClient)rect = e.ClientRectangle;
 
    using (Font font = new Font("Arial", 20 * (float)page.Zoom))
    using (StringFormat sf = new StringFormat())
    {
        switch (copyrightPlace)
        {
            case Place.TopLeft:
                sf.Alignment = StringAlignment.Near;
                sf.LineAlignment = StringAlignment.Near;
                break;
 
            case Place.TopRight:
                sf.Alignment = StringAlignment.Far;
                sf.LineAlignment = StringAlignment.Near;
                break;
 
            case Place.Center:
                sf.Alignment = StringAlignment.Center;
                sf.LineAlignment = StringAlignment.Center;
                break;
 
            case Place.BottomLeft:
                sf.Alignment = StringAlignment.Near;
                sf.LineAlignment = StringAlignment.Far;
                break;
 
            case Place.BottomRight:
                sf.Alignment = StringAlignment.Far;
                sf.LineAlignment = StringAlignment.Far;
                break;
        }
 
        e.Graphics.DrawString(copyrightString, font, Brushes.Red, rect, sf);
    }
}

示例代碼的結果如下圖所示：
