Is there a way to send back the number of rows affected on an updated with inline batch editing so that I can inform the users how many rows they have successfully updated?  I haven't been able to find anything on the web for the Kendo Grid that would help me out.  My cshtml file is

@{
        ViewData["Title"] = "Index";
}
@Html.AntiForgeryToken()
 
<h2>Index</h2>
 
@(Html.Kendo().Grid<FacilityDataManager.ViewModels.FDMError>

And my action controller (using Dapper) is shown below (curiously when I check Affected rows shows -1, so not sure why that happens)

Hello, Michael,

Thank you for the details.

The desired result can be achieved by using the count method to check for a number of updated items and then adding this value to the DataSourceResult which will be sent to the Grid:

var result /// get the data;
 
var count = errors.Count();
   
var resultFinal = result.ToDataSourceResult(request);
            return Json(new
            {
                Data = resultFinal.Data,
                Total = resultFinal.Total,
                AggregateResults = resultFinal.AggregateResults,
                Errors = resultFinal.Errors,
                count = count, // Add the extra value
            });

Then the value can be retrieved on the client on the requestEnd or dataBound events and shown to the user:

https://docs.telerik.com/kendo-ui/api/javascript/data/datasource/events/requestend

https://docs.telerik.com/kendo-ui/api/javascript/ui/grid/events/databound

I hope this is helpful.

Regards,
Stefan
