使用asp:input时Telerik RadUpload.Net2空引用

我一直在尝试使用一个简单的.aspx页面从Telerik使用RadUpload.Net2，但我得到了下一行代码的空引用：

UploadedFile file = RadUploadContext.Current.UploadedFiles[File1.UniqueID];

使用以下控件时：

<input id="File1" type="file" runat="server" />
<asp:Button ID="Button1" runat="server" Text="Button" Enabled="true" OnClick="Button1_Click"/>
<radUpload:RadProgressManager runat="server" ID="Radprogressmanager"/>
<radUpload:RadProgressArea ID="RadProgressArea1" runat="server" />

我正在使用集成了DefaultAppPool、.NET4.0的IIS 7.5。网络配置如下：

    <configuration>
    <appSettings>
    <add key="Telerik.WebControls.RadControlsDir" value="~/Resources/RadControls/" />
    <add key="Telerik.WebControls.RadUpload.TempFolder" value="D:\Projects\ODW\Temp\Upload" />
    </appSettings>
    <system.web>
    <compilation debug="true" targetFramework="4.0">

    </system.webServer>
</configuration>

处理程序已在IIS中注册。我已经在经典的.Net应用程序池上试用过，但它仍然不起作用。

RadUpload.Net2是一个非常古老的控件（2007年之前），如果您的项目在.Net 4上，您应该使用Telerik.Web.UI程序集。

这是我有许可证的版本。奇怪的是，在部署中，live Web页面可以正常工作。我只是在localhost上遇到问题。请尝试从Request.files集合获取文件。
