PDF打印-怎么把所有列打印到一页

Spread for ASP.NET 打印到 PDF 提供了强大的格式定制功能，这些功能由 PrintInfo 提供，最常见的用例之一就是当 Sheet 中有很多列时怎样把所有列打印到一页。下面就通过代码展示设置方法：

protected void Page_Load(object sender, EventArgs e)

        {

            if (IsPostBack)

                return;

            this.FpSpread1.CommandBar.ShowPDFButton = true;

            this.FpSpread1.Sheets[0].PageSize = 40;

            this.FpSpread1.Sheets[0].ColumnCount = 20;

            this.FpSpread1.Sheets[0].RowCount = 30;

            for (int i = 0; i < 20; i++)

            {

                for (int j = 0; j < 30; j++)

                {

                    this.FpSpread1.Sheets[0].Cells[j, i].Text = i.ToString() + "列" + j.ToString() + "行";

                }

            }

            FarPoint.Web.Spread.PrintInfo prinf = new FarPoint.Web.Spread.PrintInfo();

            FarPoint.Web.Spread.SmartPrintRulesCollection prules = new FarPoint.Web.Spread.SmartPrintRulesCollection();

            prules.Add(new FarPoint.Web.Spread.SmartPaperRule(FarPoint.Web.Spread.ResetOption.None));

            prinf.SmartPrintRules = prules;

            prinf.UseSmartPrint = true;

            FpSpread1.ActiveSheetView.PrintInfo = prinf;

        }
