详解NeatUpload上传控件的使用

发布时间：2010年02月01日点击数：次佚名

NeatUpload用于文件上传。可传大文件。目前最新版本：NeatUpload-1.2.32。

官方网站：http://www.brettle.com/neatupload

NeatUpload下载地址：http://www.brettle.com/Data/Sites/1/NeatUpload-1.3.21.zip

演示地址：http://www.brettle.com/Demo.aspx

1.在VS工具箱中点右键选“选择项”…… 将Brettle.Web.NeatUpload.dll添加到工具箱。

可以在添加后的工具箱看到相应控件。

2.新建web项目。将NeatUpload复制到项目根目录。

3.修改Web.config

<?xml version="1.0" encoding="utf-8"?>



<configuration>



    <configSections>

        <sectionGroup name="system.web">

            <section name="neatUpload" type="Brettle.Web.NeatUpload.ConfigSectionHandler, Brettle.Web.NeatUpload" allowLocation="true" />

        </sectionGroup>

    </configSections>



    <appSettings/>

    <connectionStrings/>



    <system.web>

        <neatUpload useHttpModule="false" maxNormalRequestLength="4096" maxRequestLength="2097151" defaultProvider="FilesystemUploadStorageProvider">

            <providers>

                <add name="FilesystemUploadStorageProvider"

                type="Brettle.Web.NeatUpload.FilesystemUploadStorageProvider, Brettle.Web.NeatUpload" />

            </providers>

        </neatUpload>

        <compilation debug="false">

        </compilation>

        <authentication mode="Windows" />

        <httpModules>

            

           <add name="UploadHttpModule" type="Brettle.Web.NeatUpload.UploadHttpModule, Brettle.Web.NeatUpload"/>

        </httpModules>

    </system.web>

    <location path="Default.aspx" >

        <system.web>

            <neatUpload useHttpModule="true" />

            <httpRuntime maxRequestLength="2097151" executionTimeout="3600" useFullyQualifiedRedirectUrl="true" />

        </system.web>

    </location>

</configuration>

现在可以拖拽控件开始编程了。
4.aspx页面代码如下：

<head runat="server">

    <title> NeatUpload </title>

    <script type="text/javascript" language="javascript">

       function ToggleVisibility(id, type)

       {

           el = document.getElementById(id);

           if(el.style)

           {

               if(type == 'on')

               {

                  el.style.display = 'block';

               }

               else

               {

                  el.style.display = 'none';

               }

           }

           else

           {

               if(type == 'on')

               {

                   el.display = 'block';

               }

               else

               {

                  el.display = 'none';

               }

           }

       }

   </script>

</head>

<body>

    <form id="form1" runat="server">

    <div>

        <Upload:InputFile ID="AttachFile" runat="server" />

   <asp:Button ID="Upload" runat="server" Text="Upload"

            OnClientClick="ToggleVisibility('ProgressBar','on')" onclick="Upload_Click" />

       <div id="ProgressBar" >

       <Upload:ProgressBar ID="pbProgressBar" runat='server' Inline="true" Width="280px"

               Height="50px">

       </Upload:ProgressBar>

   </div>

   </div>

    </form>

</body>

</html>

设计页面如下：

5.按钮事件处理函数：

protected void Upload_Click(object sender, EventArgs e)

        {

            string FileName = this.AttachFile.FileName;//获取上传文件的全路径

            string ExtenName = System.IO.Path.GetExtension(FileName);//获取扩展名

            string SaveFileName = System.IO.Path.Combine(Request.PhysicalApplicationPath, DateTime.Now.ToString("yyyyMMddhhmm") + ExtenName);//合并两个路径为上传到服务器上的全路径

            if (this.AttachFile.ContentLength > 0)

            {

                try

                {

                    this.AttachFile.MoveTo(SaveFileName, Brettle.Web.NeatUpload.MoveToOptions.Overwrite);

                }

                catch (Exception ex)

                {

                    throw ex;

                }

            }

        }

做到这里程序就可以运行的了。
默认的进度条的样式是可以修改的。
主要修改default.css、Progress.aspx及ProgressBar控件的属性。

default.css修改部分：

.ProgressDisplay .ProgressBar {

      background-color: #D7E5F7;

      background-image: url("/11.gif"); /*进度条背景图片*/

      height:20px;

}

#normalInProgress{

     color: Red;      /*进度条字体颜色*/

}

#completed{

     color:Blue;   /*上传完成的字体颜色*/

}

Progress.aspx是显示进度条的核心文件，相关数据的显示都在里面。

<td id="barTd" >

              <div id="statusDiv" runat="server" class="StatusMessage">



                   <Upload:DetailsSpan id="normalInProgress" runat="server" WhenStatus="NormalInProgress" style="font-weight: normal; white-space: nowrap;">                                <%--  正在上传时显示的   --%>

                   <%-- <%# FormatCount(BytesRead) %>/<%# FormatCount(BytesTotal) %> <%# CountUnits %> --%>

                  (<%# String.Format("{0:0%}", FractionComplete) %>) at <%# FormatRate(BytesPerSec) %>

                   <%-- - <%# FormatTimeSpan(TimeRemaining) %> left        --%>

                   </Upload:DetailsSpan>



                   <Upload:DetailsSpan id="chunkedInProgress" runat="server" WhenStatus="ChunkedInProgress" style="font-weight: normal; white-space: nowrap;">

                    <%# FormatCount(BytesRead) %> <%# CountUnits %>

                       at <%# FormatRate(BytesPerSec) %>

                       - <%# FormatTimeSpan(TimeElapsed) %> elapsed

                   </Upload:DetailsSpan>

                   <Upload:DetailsSpan id="completed" runat="server" WhenStatus="Completed">

                       <%--  上传完成时显示的   --%>

完成了: <%# FormatCount(BytesRead) %> <%# CountUnits %>

                       at <%# FormatRate(BytesPerSec) %>

                       took <%# FormatTimeSpan(TimeElapsed) %>

                   </Upload:DetailsSpan>

                   <Upload:DetailsSpan id="cancelled" runat="server" WhenStatus="Cancelled">

                       Cancelled!

                   </Upload:DetailsSpan>

                   <Upload:DetailsSpan id="rejected" runat="server" WhenStatus="Rejected">

                       Rejected: <%# Rejection != null ? Rejection.Message : "" %>

                   </Upload:DetailsSpan>

                   <Upload:DetailsSpan id="error" runat="server" WhenStatus="Failed">

                       Error: <%# Failure != null ? Failure.Message : "" %>

                   </Upload:DetailsSpan>

                   <Upload:DetailsDiv id="barDetailsDiv" runat="server" UseHtml4="true"

                        Width='<%# Unit.Percentage(Math.Floor(100*FractionComplete)) %>' class="ProgressBar"></Upload:DetailsDiv>

              </div>

         </td>
