CrystalReportViewer导出到特定的Excel工作表

Question

CrystalReportViewer允许我将报告导出到Excel文件，但它始终将报告另存为新工作表的“工作表1”。

有没有办法让CrystalReportViewer将报表保存到现有的Excel文件中，并指定在保存报表时指定什么名字？

感谢您的帮助。

禁用的CrystalReportViewer导出按钮

<CR:CrystalReportViewer .... HasExportButton="false" ... /> 

添加您的出口工具栏

<asp:Panel ID="exportPanel" ClientIDMode="Static" runat="server" CssClass="inLinePanel" > 
    <table style="height: 22px; margin-top: 1px; margin-right: 1px; margin-bottom: 1px; margin-left: 1px; display: block; cursor: pointer; " id="CrystalReportViewer1_toptoolbar_addedButtons" class="" cellspacing="0" cellpadding="0" border="0" > 
    <tr> 
    <td title="PDF"> 
    <asp:ImageButton ID="btnPdf" runat="server" OnClick="btnExport_Click" ImageUrl="~/Images/PDF.png" CssClass="AddedButton" /> 
    </td> 
    <td title="word"> 
    <asp:ImageButton ID="btnDoc" runat="server" OnClick="btnExport_Click" ImageUrl="~/Images/DOC.png" /> 
    </td> 
    <td title="excel"> 
    <asp:ImageButton ID="btnXls" runat="server" OnClick="btnExport_Click" ImageUrl="~/Images/XLS.png" /> 
    </td> 
    <td title="excel no stile"> 
    <asp:ImageButton ID="btnCsv" runat="server" OnClick="btnExport_Click" ImageUrl="~/Images/CSV.png" /> 
    </td> 
    </tr> 
</table> 
</asp:Panel> 

这是代码隐藏

protected void btnExport_Click(object sender, EventArgs e) 
{ 
ReportDocument reportDocument = CrystalReportViewer1.ReportSource ; 
    // Stop buffering the response 
    Response.Buffer = false; 
    // Clear the response content and headers 
    Response.ClearContent(); 
    Response.ClearHeaders(); 
    try 
    { 
     string senderID = ((ImageButton)sender).ID; 
     if (senderID == "btnPdf") 
      reportDocument.ExportToHttpResponse(ExportFormatType.PortableDocFormat, Response, true, Page.Title); 
     else if (senderID == "btnXls") 
      reportDocument.ExportToHttpResponse(ExportFormatType.Excel, Response, true, Page.Title); 
     else if (senderID == "btnCsv") 
      reportDocument.ExportToHttpResponse(ExportFormatType.ExcelRecord, Response, true, Page.Title); 
     else if (senderID == "btnDoc") 
      reportDocument.ExportToHttpResponse(ExportFormatType.EditableRTF, Response, true, Page.Title); 
     // There are other format options available such as Word, Excel, CVS, and HTML in the ExportFormatType Enum given by crystal reports 
    } 
    catch (Exception ex) 
    { 
     Compliance.SmtpHelper.SendErrorMessage("Reportform.Aspx - QueryString: '" + clearQueryString + "' - Dettaglio errore: " + ex.ToString()); 
     Response.Write(ex.StackTrace); 

    } 
}
