Question

我使用AjaxFileUpload控件上传多个图片文件。我正在做的是将文件保存到一个文件夹，然后将其插入数据库。我的表格字段为id，url，alt。我还想为图像输入Alternate Text，以便它显示为图像的描述。如何在AjaxFileUpload控件中对其进行编辑。对于每个图像，我上传一个文本框以接受应该出现的替换文本。我怎样才能做到这一点。是否有可能这样做。??

这是我的aspx代码：

<div id="sliderinsert" style="position:absolute; padding-bottom:5px; background-color:gray; top: 24px; left: 13px; 
    width: 695px; height: 300px; margin-bottom: 1px; overflow:visible">

        <ajaxToolkit:AjaxFileUpload style="position:absolute; width:695px; overflow:auto;max-height:600px"  MaximumNumberOfFiles="7" AllowedFileTypes="jpg,jpeg,png,gif"  
            id="ajaxUpload1"  OnUploadComplete="ajaxUpload1_UploadComplete" runat="server" Width="633px"/>

        <asp:ScriptManager ID="ScriptManager1" runat="server">
        </asp:ScriptManager>

    </div>

这是我背后的代码：

protected void ajaxUpload1_UploadComplete(object sender, AjaxControlToolkit.AjaxFileUploadEventArgs e)
{
     id+=1;
    string filename = Path.GetFileName(e.FileName);
    string filepath = Server.MapPath("~/Images/Gallery/" + filename);
    ajaxUpload1.SaveAs(filepath);

    string Insert = "Insert into slider (slid,slurl) values (@id,@IMAGE_PATH)";
    SqlCommand cmd = new SqlCommand(Insert, con);
    cmd.Parameters.AddWithValue("@IMAGE_PATH", filepath);
    cmd.Parameters.AddWithValue("id", id);
    try
    {
        con.Open();
        cmd.ExecuteNonQuery();
    }
    catch (Exception ex)
    {
        Response.Write(ex.Message);
    }
    finally
    {
        con.Close();
        cmd.Dispose();
    }    
}
