我正在与球员和篮球队一起创建一个项目表格。我使用listview（asp.net）。
我想在edititem和insertitem上发布一个上传活动。我想上传图片
~/images/，文件名为"SURNAME" (Column from databse) + ".jpg。
只有那个
来自players.asp文件的我的ASP代码是：
<asp:ListView ID="ListView1" runat="server" DataKeyNames="ID,IDOTEAM,IDOCOUNTRY" DataSourceID="SqlDataSource1" InsertItemPosition="LastItem">

fu2.SaveAs(Server.MapPath("~/images/" + aut.ToString() ));
ErrorLabel1.Text = "ok";
}
else
{
ErrorLabel1.Text = "no";
}
}
}
fileuploader无法正常工作。我不想获取上传的每个图像的文件名。我只想获取"SURNAME"字符串并将文件另存为"SURNAME" +".jpg"
非常感谢你

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： （已编辑以反映所请求的更改）
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对话：What are the naming guidelines for ASP.NET controls?。
答案 1 :(得分：0)
此代码有错误。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");
