我正在创建一个带有表格的球员和篮球队的项目。我使用listview（asp.net）。

我想在edititem和上进行上传活动insertitem。我想 ~/images/用文件名上传图像"SURNAME" (Column from databse) + ".jpg。只有这样

我的 player.asp 文件中的 ASP 代码是：

    <asp:ListView ID="ListView1" runat="server" DataKeyNames="ID,IDOTEAM,IDOCOUNTRY" DataSourceID="SqlDataSource1" InsertItemPosition="LastItem">
        <AlternatingItemTemplate>
            <tr style="background-color: #fff7f1; color: #800000;">
                <td>
                    <asp:Button ID="DeleteButton" runat="server" CommandName="Delete" Text="Διαγραφή" />
                    <asp:Button ID="EditButton" runat="server" CommandName="Edit" Text="Επεξεργασία" />
                </td>
                <td>
                    <asp:Label ID="IDLabel" runat="server" Text='<%# Eval("ID") %>' />
                </td>
                <td>

                </td>

我在文件 player.cs 中的 cs 代码是：

enter code here

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class AddPlayers : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

}

protected void ListView1_SelectedIndexChanged(object sender, EventArgs e)
{

}

protected void ListView1_ItemCommand(object sender,ListViewInsertEventArgs e)
{


                FileUpload fu2 = (FileUpload)ListView1.InsertItem.FindControl("FileUpload2");
                if (fu2.HasFile)
                {
                    string aut = "pol.jpg";
                    fu2.SaveAs(Server.MapPath("~/images/" + aut.ToString()  ));
                    ErrorLabel1.Text = "ok";

                }
                else
                {
                                ErrorLabel1.Text = "no";

                }


    }

}

文件上传器不工作。我不想获取上传的每张图片的文件名。我只想获取"SURNAME"字符串并将文件保存为"SURNAME" +".jpg" 非常感谢

我会在标记中附加 ItemCommand 事件：

<asp:ListView ID="ListView1" runat="server" DataKeyNames="ID,IDOTEAM,IDOCOUNTRY" 
        DataSourceID="SqlDataSource1" InsertItemPosition="LastItem" 
        OnItemCommand="ListView1_ItemCommand" >

在代码中：（已 编辑以反映请求的更改）

protected void ListView1_ItemCommand(object sender, ListViewCommandEventArgs e)
{
    if (e.CommandName == "Update")
    {
        TextBox txtSurName = (TextBox)ListView1.InsertItem.FindControl("SURNAMETextBox");
        TextBox txtFirstName = (TextBox)ListView1.InsertItem.FindControl("FIRSTNAMETextBox");
        FileUpload fu1 = (FileUpload)ListView1.InsertItem.FindControl("FileUpload1");
        if (fu1.HasFile)
        {
            string aut = String.Format("{0}{1}{3}", txtFirstName.Text, txtFirstName.Text, ".jpg");
            fu1.SaveAs(Server.MapPath("~/images/" + aut));
            ErrorLabel1.Text = "ok";

        }
        else
        {
            ErrorLabel1.Text = "no";

        }

    }
    else if (e.CommandName == "INSERT")
    {
        TextBox txtSurName = (TextBox)ListView1.InsertItem.FindControl("SURENAMETextBox");
        TextBox txtFirstName = (TextBox)ListView1.InsertItem.FindControl("TextBox1");
        FileUpload fu2 = (FileUpload)ListView1.InsertItem.FindControl("FileUpload2");
        if (fu2.HasFile)
        {
            string aut = String.Format("{0}{1}{3}", txtFirstName.Text, txtFirstName.Text, ".jpg");
            fu2.SaveAs(Server.MapPath("~/images/" + aut));
            ErrorLabel1.Text = "ok";

        }
        else
        {
            ErrorLabel1.Text = "no";

        }
    }
}

我还强烈建议遵循一些命名约定：ASP.NET 控件的命名准则是什么？.

这段代码有错误。您必须确保在处理 EditItem 时必须使用

TextBox txtSurName = (TextBox)ListView1.EditItem.FindControl("SURENAMETextBox");

不是

TextBox txtSurName = (TextBox)ListView1.InsertItem.FindControl("SURENAMETextBox");
