ReportViewer在WEB FORM的TOOL BAR 有個匯出的功能，有USER反應他在IE6執行時，匯出會多一產生一個空白頁。

於是我自製了一個匯出的功能，來取代原TOOL BAR 的匯出

 

 

   /// <summary>
    /// 呼叫此function將rdl檔賦予資料後進行匯出
    /// </summary>
    /// <param name="pType">支援PDF、Excel、Image等格式</param>
    public void ExportReport(string pType,string FileName)
    {
        Warning[] warnings;
        string[] streamids;
        string mimeType;
        string encoding;
        string extension;
        string deviceInfo;

        deviceInfo = "<DeviceInfo><SimplePageHeaders>True</SimplePageHeaders></DeviceInfo>";

        byte[] bytes = ReportViewer.ServerReport.Render(pType, null, out mimeType, out encoding
            , out extension,out streamids, out warnings);

        Response.Clear();

        // 使用 UTF8 編碼
        Response.HeaderEncoding = System.Text.Encoding.UTF8;
        Session.CodePage = 65001;
        Response.Charset = "UFT8";
        Response.ContentType = mimeType;
        Response.AppendHeader("Content-Disposition", String.Format("attachment; filename={0}.{1}", FileName, extension));
        Response.BinaryWrite(bytes);
        Response.End();
    }

    protected void btnExport_Click(object sender, EventArgs e)
    {
        ExportReport("PDF", "Terminal");
    }
