如何将WebDataGridview的数据导出到现有Excel工作表？

Question

我有一个Webdatagridview，我想将它的数据（不包括标题，因为我的excel文件已经有标题）导出到我现有的Excel文件中。

Answer 1

If you are using the Infragistics WebDataGrid, you can use the WebExcelExporter and use an overload for the Export method that takes and instance of a workbook or worksheet.

For preventing the headers set the ShowHeader property of the WebDataGrid that you are exporting to false before calling Export. Note that this will not need to be set back to true since the response is being changed to send the excel file to the client so there is no state information for the grid sent to the client for this request.

try:

 protected void ExportToExcel()
 {
        Response.Clear();
        Response.Buffer = true;
        Response.ContentType = "application/vnd.ms-excel";
        Response.AddHeader("content-disposition", "attachment;filename=YourFiles.xls");
        Response.Charset = "";
        this.EnableViewState = false;

        System.IO.StringWriter sr = new System.IO.StringWriter();
        System.Web.UI.HtmlTextWriter htw= new System.Web.UI.HtmlTextWriter(sr);

        gvFiles.RenderControl(htw);

        Response.Write(sw.ToString());
        Response.End();
    }
