Question

我正在开发一个项目，我想下载gridview行数据，但它对我不起作用。这是我用于下载的代码：

string fileName = "chhattisgarhishafte" + DateTime.Now.ToString() + ".doc";
                    GridView1.DataSource = dtD;
                    GridView1.DataBind();

                    Response.Clear();
                    Response.Buffer = true;

                    Response.AddHeader("content-disposition", "attachment;filename=" + fileName);
                    Response.Charset = "";
                    Response.ContentType = "application/vnd.ms-word ";
                    StringWriter sw = new StringWriter();
                    HtmlTextWriter hw = new HtmlTextWriter(sw);

                    GridView1.AllowPaging = false;
                    GridView1.DataBind();

                    GridView1.RenderBeginTag(hw);
                    GridView1.RenderControl(hw);
                    Response.Output.Write(sw.ToString());
                    GridView1.RenderEndTag(hw);
                    Response.Flush();
                    Response.End();

stD是datatble，用于存储gridview选定的行。

错误是：

Control 'ctl00_ContentPlaceHolder1_GridView1' of type 'GridView' must be placed inside a form tag with runat=server.

Answer 1

请在母版页的表格标签中使用runat =“server”

Answer 2

使用此代码，它在我的应用程序中工作

            if (gv.Rows.Count > 0)
            {

                StringWriter tw = new StringWriter();
                HtmlTextWriter hw = new HtmlTextWriter(tw);

                //Get the HTML for the control.
                gv.RenderControl(hw);
                //Write the HTML back to the browser.
                //Response.ContentType = application/vnd.ms-excel;
                Response.ContentType = "application/vnd.ms-excel";
                Response.AppendHeader("Content-Disposition", "attachment; filename=" + strFileName);
                EnableViewState = false;
                Response.Write(tw.ToString());
                Response.End();
            }
