Question

以前我可以从gridview和GridView1_RowCommand

中的代码下载文件

代码是

 protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName == "cmd")
        {
            string filename = e.CommandArgument.ToString();
            string path = MapPath("~/Docfiles/" + filename);
            byte[] bts = System.IO.File.ReadAllBytes(path);
            Response.Clear();
            Response.ClearHeaders();
            Response.AddHeader("Content-Type", "Application/octet-stream");
            Response.AddHeader("Content-Length", bts.Length.ToString());
            Response.AddHeader("Content-Disposition", "attachment; filename=" +
            filename);
            Response.BinaryWrite(bts);
            Response.Flush();

但是现在我创建一个表并显示一些数据，我想在表中下载一个链接这是表格代码......

<div class="CSSTableGenerator" >
            <table border="0" width="100%" cellpadding="0" cellspacing="0" 
              id="results">
            <asp:Repeater ID="Repeater1" runat="server">
            <HeaderTemplate>
                <tr>
                    <td>
                       Document ID
                    </td>
                    <td >
                        Document Name
                    </td>
                    <td>
                        File Uploaded
                    </td>
                    <td>
                       Document Type
                    </td>

                </tr>
                </HeaderTemplate>
                <ItemTemplate>
                <tr>
                <%--<td><asp:LinkButton ID="LinkButton1" runat="server"
                CommandArgument='<%# Eval("FileUploaded") %>' 
           CommandName="cmd">Download</asp:LinkButton></td>--%>
                <td><%#DataBinder.Eval(Container.DataItem,"DocumentID") %></td>

                <td><%#DataBinder.Eval(Container.DataItem, "
                     DocumentName")%> </td>
                <td><%#DataBinder.Eval(Container.DataItem,
                                "FileUploaded")%></td>
                <td><%#DataBinder.Eval(Container.DataItem, 
                      "Document")%></td>
                </tr>
                </ItemTemplate>
                </asp:Repeater> 
                <div id="pageNavPosition" >
                </div>              
            </table>
            </div>

现在如何在表格中添加下载链接以及我写的内容而不是GridView1_RowCommand ????

任何解决方案？

Answer 1

据我所知，您将文件存储在名为“Docfiles”的文件夹中。您只需要在此文件的ItemTemplate中添加超链接

<td><a href="/Docfiles/<%#DataBinder.Eval(Container.DataItem, "DocumentName")%>">Download</a></td>

此场景中不需要GridView1_RowCommand

在html表中下载链接
