使用Aspxuploadcontrol控件时文件未上载

问题描述

这是设计代码：

This is the design Code :

<%@ Import Namespace=" Purple.WebDesk.Models" %>
<%@ Page Title="" Language="C#" MasterPageFile="~/Shared/Site.Master" AutoEventWireup="true" CodeBehind="test.aspx.cs" Inherits="Purple.WebDesk.test" %>
<%@ Register Assembly="DevExpress.Web.v14.2, Version=14.2.5.0, Culture=neutral, PublicKeyToken=b88d1754d700e49a" Namespace="DevExpress.Web" TagPrefix="dx" %>
<%@ Register Src="~/Shared/UploadedFilesContainer.ascx" TagPrefix="dx" TagName="UploadedFilesContainer" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
    <style type="text/css">
        .uploadContainer
        {
            float: left;
            margin-right: 80px;
        }
        .contentFooter
        {
            clear: both;
            padding-top: 20px;
        }
    </style>
    <script type="text/javascript">
        function onFileUploadComplete(s, e) {
            if (e.callbackData) {
                var fileData = e.callbackData.split('|');
                var fileName = fileData[0],
                    fileUrl = fileData[1],
                    fileSize = fileData[2];
                FileContainer.AddFile(fileName, fileUrl, fileSize);
            }
        }
    </script>
</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
    <div class="uploadContainer">
        <dx:ASPxUploadControl ID="UploadControl"  runat="server" ClientInstanceName="UploadControl" Width="320"

            NullText="Select multiple files..." UploadMode="Advanced" ShowUploadButton="True" ShowProgressPanel="True"

            >
            <AdvancedModeSettings EnableMultiSelect="True" EnableFileList="True" EnableDragAndDrop="True" />
            <ValidationSettings MaxFileSize="4194304" AllowedFileExtensions=".jpg,.jpeg,.gif,.png">
            </ValidationSettings>
            <ClientSideEvents FileUploadStart="function(s, e) { FileContainer.Clear(); }"

                              FileUploadComplete="onFileUploadComplete" />
        </dx:ASPxUploadControl>

        <br /><br />
        <p class="note">
            <dx:ASPxLabel ID="AllowedFileExtensionsLabel"  runat="server" Text="Allowed file extensions: .jpg, .jpeg, .gif, .png." Font-Size="8pt">
            </dx:ASPxLabel>
            <br />
            <dx:ASPxLabel ID="MaxFileSizeLabel"  runat="server" Text="Maximum file size: 4 MB." Font-Size="8pt">
            </dx:ASPxLabel>
        </p>
    </div>
    <div>
        <dx:UploadedFilesContainer ID="FileContainer"  runat="server" Width="380" Height="180" 

            NameColumnWidth="240" SizeColumnWidth="70" HeaderText="Uploaded files" />
    </div>
    <div class="contentFooter">
        <p class="Note">
            Note: All files uploaded will be automatically deleted in 5 minutes.
        </p>
    </div>
</asp:Content>

这是cs代码：

this is the cs code :

const string UploadDirectory = @"D:\Projects\MojKw\Production\Purple\Trunk\Code\Purple.WebDesk\Shared";

        protected void ASPxUploadControl1_FileUploadComplete(object sender, FileUploadCompleteEventArgs e)
        {
            string resultExtension = Path.GetExtension(e.UploadedFile.FileName);
            string resultFileName = Path.ChangeExtension(Path.GetRandomFileName(), resultExtension);
            string resultFileUrl = UploadDirectory + resultFileName;
            string resultFilePath = MapPath(resultFileUrl);
            e.UploadedFile.SaveAs(resultFilePath);

            UploadingUtils.RemoveFileWithDelay(resultFileName, resultFilePath, 5);

            string name = e.UploadedFile.FileName;
            string url = ResolveClientUrl(resultFileUrl);
            long sizeInKilobytes = e.UploadedFile.ContentLength / 1024;
            string sizeText = sizeInKilobytes.ToString() + " KB";
            e.CallbackData = name + "|" + url + "|" + sizeText;
        }

当我点击上传按钮时文件无法上传原因？

我是什么错过了这段代码

when i click on upload button the file not upload why ?
what i missed in this code

推荐答案

<dx:aspxuploadcontrol id="ASPxUploadControl1"  runat="server" xmlns:dx="#unknown">
    OnFileUploadComplete="ASPxUploadControl1_FileUploadComplete"
    FileUploadMode="OnPageLoad">
    <clientsideevents fileuploadcomplete="function(s, e) {<br mode=" hold=" /> window.open(e.callbackData);<br mode=" /></dx:aspxuploadcontrol>

protected void ASPxUploadControl1_FileUploadComplete（object sender，FileUploadCompleteEventArgs e）

{

if （e.IsValid）

{

fileinfo = new System.IO.FileInfo（e.UploadedFile.FileName）;

resfilename = MapPath（System.Web.Configuration.WebConfigurationManager.AppSettings [DocumentPath]。ToString（））+\\ \\\+ fileinfo.Name;

e.UploadedFile.SaveAs（resfilename）;



//Response.ContentType =Application / pdf;

//Response.TransmitFile(resfilename）;

//Response.End（）;



}



}

protected void ASPxUploadControl1_FileUploadComplete(object sender, FileUploadCompleteEventArgs e)
{
if (e.IsValid)
{
fileinfo = new System.IO.FileInfo(e.UploadedFile.FileName);
resfilename = MapPath(System.Web.Configuration.WebConfigurationManager.AppSettings["DocumentPath"].ToString()) + "\\" + fileinfo.Name;
e.UploadedFile.SaveAs(resfilename);

//Response.ContentType = "Application/pdf";
//Response.TransmitFile(resfilename);
//Response.End();

}

}
