问题描述

我需要从datagrid的每一行中的磁盘中选择文件.我正在按以下方式使用FileUpload，但无法访问

Hi,

I need to select file from disk in each row of datagrid. I am using FileUpload as following but its not accessable

fu = (FileUpload)row.FindControl("fu_doc");

在服务器端.

on server side.

<asp:TemplateField HeaderText="Select file">
 <itemtemplate>
   <asp:FileUpload ID="fu_doc"; runat="server"> 
 </itemtemplate>

有任何建议吗?

Any suggestion?

推荐答案

try:

try:

  <asp:TemplateField HeaderText="Logo Upload">
    <ItemTemplate>
        <asp:FileUpload ID="FileUpload4" runat="server" /><asp:Button ID="bt_upload" runat="server" EnableViewState="False" Text="Upload" CommandName="Upload" />
</ItemTemplate>
</asp:TemplateField>

并在服务器端:

and in the serverside:

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
   {
       Button bts = e.CommandSource as Button;
       Response.Write(bts.Parent.Parent.GetType().ToString());
       if (e.CommandName.ToLower() != "upload")
       {
           return;
       }
       FileUpload fu = bts.FindControl("FileUpload4") as FileUpload;//here
       if (fu.HasFile)
       {
           bool upload = true;
           string fleUpload = Path.GetExtension(fu.FileName.ToString());
           if (fleUpload.Trim().ToLower() == ".xls" | fleUpload.Trim().ToLower() == ".xlsx")
           {
               fu.SaveAs(Server.MapPath("~/UpLoadPath/" + fu.FileName.ToString()));
               string uploadedFile = (Server.MapPath("~/UpLoadPath/" + fu.FileName.ToString()));
               //Someting to do?...
           }
           else
           {
               upload = false;
               // Something to do?...
           }
           if (upload)
           {
               // somthing to do?...
           }
       }
       else
       {
           //Something to do?...
       }
   }
