radcontrol radupload 上传控件的学习与使用

1.web.config  中需要加入：
 <httpHandlers>
    <add verb="*" path="Telerik.RadUploadProgressHandler.aspx" type="Telerik.WebControls.RadUploadProgressHandler, RadUpload.Net2" />
 </httpHandlers>
 <httpModules>
      <add name="RadUploadModule" type="Telerik.WebControls.RadUploadHttpModule, RadUpload.Net2" />
 </httpModules>

2.引用并声明使用
<%@ Register TagPrefix="radU" Namespace="Telerik.WebControls" Assembly="RadUpload.NET2" %>
<radU:RadProgressManager ID="Radprogressmanager1" runat="server" />
<radU:RadUpload ID="RadUpload1" runat="server" Skin="Web20" InitialFileInputsCount="2"
                    MaxFileInputsCount="4" AllowedFileExtensions=".doc,.rar" MaxFileSize="10000000"
                    TargetFolder="~/Upload/kjcx" OverwriteExistingFiles="false" />
<asp:Button ID="buttonSubmit" runat="server" CssClass="RadUploadButton" Text="Submit!" />
<radU:RadProgressArea ID="progressArea1" runat="server" />
