Upload not working on prod

[Davide]

Hello,

We developed a simple upload functionality which works correctly on test environment but not in prod.

The expected behavior is whenever clicked on "browse", the file being uploaded and written into the RadUploadTemp. Once clicked on "upload" button, the code behind is raised but UpladedFiles collection is empty.

Note that RadUploadTemp has been created automatically and even the zero bytes file name: RadUploadTestFile

The only apparent difference between test and prod seems to be that into prod's web.config this section is missed: 

<configSections>
  <sectionGroup name="system.web.extensions" type="System.Web.Configuration.SystemWebExtensionsSectionGroup, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
    <sectionGroup name="scripting" type="System.Web.Configuration.ScriptingSectionGroup, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
      <section name="scriptResourceHandler" type="System.Web.Configuration.ScriptingScriptResourceHandlerSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="MachineToApplication" />
      <sectionGroup name="webServices" type="System.Web.Configuration.ScriptingWebServicesSectionGroup, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
        <section name="jsonSerialization" type="System.Web.Configuration.ScriptingJsonSerializationSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="Everywhere" />
        <section name="profileService" type="System.Web.Configuration.ScriptingProfileServiceSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="MachineToApplication" />
        <section name="authenticationService" type="System.Web.Configuration.ScriptingAuthenticationServiceSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="MachineToApplication" />
        <section name="roleService" type="System.Web.Configuration.ScriptingRoleServiceSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="MachineToApplication" />
      </sectionGroup>
    </sectionGroup>
  </sectionGroup>
</configSections>

ASPX:

<%-- uploader --%>
<div id="divUploader" runat="server" class="divUploader" visible=' <%# DataBinder.Eval(((IDataItemContainer)Container).DataItem, "uploadervisible") %>'>
    <span class="spText">Restituzione Documentazione</span>
    <a runat="server" class="tooltip" href="javascript:void(0);"
        visible='<%# DataBinder.Eval(((IDataItemContainer)Container).DataItem, "tooltipvisible") %>'
        title='<%# DataBinder.Eval(((IDataItemContainer)Container).DataItem, "tooltiptext") %>'>
        <asp:Image ImageUrl="~/images/icoTooltip.png" runat="server" />
    </a>
    <telerik:RadAsyncUpload RenderMode="Lightweight" runat="server" CssClass="async-attachment" ID="FileUpload"
            HideFileInput="false"  MaxFileInputsCount="1" MultipleFileSelection="Disabled"  CommandName="Upload" CommandArgument='<%# DataBinder.Eval(((IDataItemContainer)Container).DataItem, "iPtAcq") %>'
            AllowedFileExtensions=".pdf"  ControlObjectsVisibility="None">
            <Localization Select="Sfoglia..." />
            <Localization Remove="" />
    </telerik:RadAsyncUpload>
    <asp:Button ID="btnFileUpload" runat="server" CssClass="btnOrangeUpload" Text="Carica" CommandName="Upload" CommandArgument='<%# DataBinder.Eval(((IDataItemContainer)Container).DataItem, "iPtAcq") %>' />
    <%--<asp:FileUpload ID="FileUpload" runat="server" class="file" />--%>
</div>

 

 

Can anyone give a clue how can I check in order to fix this?

Feel free to ask me more details if needed...

Regards.

Hello Davide,

I am afraid that the provided information is insufficient to determine what is preventing the proper upload of the files. 

Please find attached a sample project that we used to recreate the scenario and is uploading as expected. 

Also, I would recommend reviewing the web.config Settings Overview article to better understand the web.config and the required configurations and handler registrations. 

If the issue is not replicated in the attached project, would you please modify it so that it demonstrates the problem and send it back to us in an official support ticket? Thus, we would be able to investigate locally and help you more efficiently.  

Meanwhile, would you please check if there are any JavaScript errors in the browser console and if there are any failing requests to the server? 

Another thing you could check is if the production project has all the necessary permissions. 

Regards,
Peter Milchev
