I am using KendoUI (upload) and I am trying to receive a file in a method in webapi from Kendo UI (upload) but the object received is null.
 
In the Index.cshtml



In webapi:
SaveController.cs



Please, I need an example for this situation. Thanks.

Hello Ever,

The sample code is missing from the post, could you please post it again? In general the WebAPI will not automatically decode multi-part form data requests, so it is up to the developer to achieve this.

Hello Dimiter,

I understand it, I would like to show you the example and my situation.

In the Index.cshtml

            <input type="file" name="files"
                    kendo-upload k-async="{ saveUrl: 'http://localhost:25193/api/Save', 
                                                             removeUrl: 'http://localhost:25193/api/remove/remove', autoUpload: true }"
                    k-select="onFileSelect"
                    k-multiple="false"
                    k-upload="onFileUpload" />

In webapi:
SaveController.cs

[HttpPost]
[HttpOptions]
public HttpResponseMessage Save(HttpPostedFileBase file)
{
    if (file != null) //This object is received Null
               {
       return Request.CreateResponse(HttpStatusCode.OK);
    }
    else
    {
       return Request.CreateResponse(HttpStatusCode.NotFound);
    }
}


1- When I specify (in the upload KendoUI) to call the webapi. In the webapi, the object (file sent from upload KendoUI) received is null.
2- When I specify (in the upload Kendo UI) to call an action in the Controller in the project MVC (Visual Studio). The object received in the action is not null, it is ok.

I would like to know your advice. Thanks.

Hello Ever,

This is what I tried to explain in my previous post - the request won't be resolved automatically as an HttpPostedFileBase and this is up to the developer when uploading files to WebAPI. The complete approach is described on the following page, which also includes an example.

Hello Ever, I have the same issue, did you find a solution for this? HttpPostedFileBase this is the model I am using the API controller to receive the file but I see the file object is always null. Please let me know if you have any solution for this. Thanks.

Hello Murali,

As stated previously, the request won't be resolved automatically as an HttpPostedFileBase. An example approach to achieve this is demonstrated on the following page.
