[Solved] Row not returned after insert with WebAPI

[Wim]

When using inline editing in the Grid, all entries are added again for each new row I add. I've tracked this down and it seems to be caused by not returning the inserted row to the Grid, which is why the ID stays 0 and every row is treated as a new row each time.

I've tried to solve this, but even using the example from the docs, I can't get it to work.

My grid uses this WebAPI call to insert a row. How should I change it to return the row correctly, including the ID?

public HttpResponseMessage Post(Batch model)
{
    HttpResponseMessage response;

    if (ModelState.IsValid) {
        service.Create(model.ReceiptLineURID, model);

        DataSourceResult result = new DataSourceResult {
            Data = new[] { model },
            Total = 1
        };

        response = Request.CreateResponse(HttpStatusCode.Created, result);
        response.Headers.Location = new Uri(Url.Link("DefaultApi", new { id = model.BatchNo }));
    } else {
        response = Request.CreateErrorResponse(HttpStatusCode.BadRequest, ModelState);
    }

    return response;
}

Hello Wim,

Could you please confirm that you actually have the updated item when returning the response from the server. In other words if you have the same as the example like ours:

service.Create(model.ReceiptLineURID, model);

  
-> Could you please confirm that model.Id at this point is different than 0? <-

        DataSourceResult result = new DataSourceResult {

            Data = new[] { model },

            Total = 1

        };

If it is then it should mark the created item as successfully updated. In case still the client side sends the record for creation and the model is actually updated we will need a small sample project or a LIVE URL to visit and investigate on.

Kind Regards,

The ID was indeed 0, once I made sure it was set to the new value, everything worked as expected. Thank you!
