We implemented what is described in the pages 'igupload-using-http-handler-and-modules' and 'using-ignite-ui-nugget-packages'. Since we already have the upload code working on the client-side, we did not implement any of the server-side code described by the other web pages.

Unfortunately, after issuing the igUpload command at the client, the calls to the server fail with 404 errors. We've used the same client-side code with the ASP.NET version of the server-side dll and everything works fine.

The following is what we have in the web.config.

<system.webServer>

<validation validateIntegratedModeConfiguration="false" />

<modules runAllManagedModulesForAllRequests="true">

<remove name="WebDAVModule" />

 <add name="IGUploadModule" type="Infragistics.Web.Mvc.UploadModule" preCondition="managedHandler" />

</modules>

<handlers>

<remove name="WebDAV" />

<add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" />

 <add name="IGUploadStatusHandler" path="IGUploadStatusHandler.ashx" verb="*" type="Infragistics.Web.Mvc.UploadStatusHandler" preCondition="integratedMode" />

</handlers>

<aspNetCore processPath="%LAUNCHER_PATH%" arguments="%LAUNCHER_ARGS%" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" forwardWindowsAuthToken="false"></aspNetCore>

Our Dependencies include both NuGet packages IgniteUI and IgniteUI.MVC (version 16.2.20162.2040 for both).

The client-side script to perform the upload is as follows:

$("#ATigUpload1").igUpload({

  mode: 'multiple',

  multipleFiles: true,

  autostartupload: true,

  progressUrl: "/IGUploadStatusHandler.ashx",

  uploadUrl: "/ig_fua34sf345sdf13sdf3454erdsf2345asd3425df5235d54df345.aspx",

  maxSimultaneousFilesUploads: 2,

  controlId: "serverID1",

  fileUploading: function (evt, ui) { ... },

  fileUploaded: function (evt, ui) { ... },

  fileSelected: function (evt, ui) { ... },

  fileSelecting: function (evt, ui) { ... },

  onError: function (evt, ui) { ... },

  fileUploadAborted: function (evt, ui) { ... }       

});

Do you have a solution that you can provide where you have it working?

Hello,

I am attaching the modified version of your sample that is working for me. Please let me know what you see when you run it.

I found the hander in your solution. Apparently it didn't get published, so I copied it manually. However, it still doesn't work.

Hello,

I left the handler file in the folder but it was excluded from the project as it should not be used. And the upload will have its own created. What happens when you exclude the handler.

You may get several posts from me. Once I do a post I keep getting the message that the forum is managed and that my posts must first be approved. Other times it gets added automatically.

However, running the solution as sent also returns the 504 error.

Hello,

Thank you for the update. Can you tell me more about your setup? What is your OS? What browser are you using? What version of the browser? Do you have a full network log of the traffic when that error occurs that you can attach?
