WinForm应用程序的导出

Winform平台下用viewer1展示报表默认的情况下，是没有导出按钮的，需要进行导出按钮的添加和对应的Click事件。

默认情况下生成后，如下图：（没有导出EXCEL的按钮）

添加导出EXCEl按钮后后：

1、添加导出EXCEL的方法

第一种办法在designer中添加按钮，具体代码如下：

          //Remove the print button.
           viewer1.Toolbar.ToolStrip.Items.RemoveAt(2);//移除
           //Remove the extra separator.
           viewer1.Toolbar.ToolStrip.Items.RemoveAt(1);
           //Add a new button to the end of the tool strip with the caption "Excel."
           ToolStripButton tsbExcel = new ToolStripButton("导出Excel");
           viewer1.Toolbar.ToolStrip.Items.Add(tsbExcel);//添加
           //Create a click event handler for the button.
           tsbExcel.Click += new EventHandler(tsbExcel_Click);//Click事件

第二种办法可以在from_Load中进行按钮的添加

private ToolStripButton tsbExcel = new System.Windows.Forms.ToolStripButton();
        private void Form1_Load(object sender, EventArgs e)
        {
            this.viewer1.Visible = true;
            System.Windows.Forms.ToolStrip toolStrip;
            System.Windows.Forms.ToolStripItem orgItem;
            System.Windows.Forms.ToolStripButton orgBtn = null;

            toolStrip = this.viewer1.Toolbar.ToolStrip;
            orgItem = toolStrip.Items[2];
            if (orgItem is System.Windows.Forms.ToolStripButton)
            {
                orgBtn = (System.Windows.Forms.ToolStripButton)orgItem;
            }
            toolStrip.Items.RemoveAt(2);
            tsbExcel.Text = "导出";
            tsbExcel.Image = orgBtn.Image;
            tsbExcel.Enabled = false;

            tsbExcel.Click += this.btnExcel_Click;
            toolStrip.Items.Insert(2, tsbExcel);
            GrapeCity.ActiveReports.PageReport rpt = new GrapeCity.ActiveReports.PageReport(new System.IO.FileInfo(@"RdlReport2.rdlx"));
            GrapeCity.ActiveReports.Document.PageDocument rptb = new GrapeCity.ActiveReports.Document.PageDocument(rpt);
            this.viewer1.LoadDocument(rptb);
        }
     两种办法都可以进行按钮的添加，但是我建议大家用第一种方法：

2、导出的click事件的编码：

导出EXCEL的形式有两种办法：

第一种Rendering Extensions

private void tsbExcel_Click(object sender, EventArgs e)
      {
          System.IO.DirectoryInfo outputDirectory = new System.IO.DirectoryInfo(@"D:\MyExcel");
          outputDirectory.Create();

          GrapeCity.ActiveReports.Export.Excel.Page.ExcelRenderingExtensionSettings excelSetting = new GrapeCity.ActiveReports.Export.Excel.Page.ExcelRenderingExtensionSettings();
          excelSetting.FileFormat = GrapeCity.ActiveReports.Export.Excel.Page.FileFormat.Xls;
          excelSetting.MultiSheet = false;
          GrapeCity.ActiveReports.Extensibility.Rendering.ISettings setting = excelSetting;

GrapeCity.ActiveReports.Export.Excel.Page.ExcelRenderingExtension excelRenderingExtension = new GrapeCity.ActiveReports.Export.Excel.Page.ExcelRenderingExtension();

GrapeCity.ActiveReports.Rendering.IO.FileStreamProvider outputProvider = new GrapeCity.ActiveReports.Rendering.IO.FileStreamProvider(outputDirectory, System.IO.Path.GetFileNameWithoutExtension(outputDirectory.Name));
outputProvider.OverwriteOutputFile = false;

_document.Render(excelRenderingExtension, outputProvider, excelSetting.GetSettings());
}

第二种Export Filters

private void btnExcel_Click(object sender, EventArgs e)
     {
         GrapeCity.ActiveReports.PageReport rpt = new GrapeCity.ActiveReports.PageReport(new System.IO.FileInfo(@"RdlReport2.rdlx"));
         GrapeCity.ActiveReports.Document.PageDocument _reportRuntime = new GrapeCity.ActiveReports.Document.PageDocument(rpt);

GrapeCity.ActiveReports.Export.Excel.Section.XlsExport XlsExport1 = new GrapeCity.ActiveReports.Export.Excel.Section.XlsExport();

         System.IO.MemoryStream ms = new System.IO.MemoryStream();
         XlsExport1.FileFormat = GrapeCity.ActiveReports.Export.Excel.Section.FileFormat.Xlsx;
         XlsExport1.Export(_reportRuntime, ms);
     }
