ToDataSourceResult with additional value(s)

[Robert Madrian]

Hello,

is there any possibility to add an additional value to the ToDataSourceResult in the Kendo read Action to pass that value with
the Ajax request to the Client?

return Json(result.ToDataSourceResult(request));

 

Background: we have a paged grid and in my action I pass the ID of a row which is added to the database with a Ajax form outside the grid
and calculate on the Server the page for that row so I want to pass that page as an additional value to the client:

Hello, Robert,

Inside the Read action in the Controller create a custom Json result based on the result of the ToDataSourceResult method and the additional value:

var result /// get the data;

var resultFinal = result.ToDataSourceResult(request);
            return Json(new
            {
                Data = resultFinal.Data,
                Total = resultFinal.Total,
                AggregateResults = resultFinal.AggregateResults,
                Errors = resultFinal.Errors,
                myProperty1 = "extra value", // Add the extra value
            });

I hope this is helpful.

Hello,

where is the best Event to get the myProperty1 value?

is it also possible to get the value in the dataBound Event?

Hello Robert,

The dataSource requests the server, then maps the response and populates the grid. Therefore, the raw response from the server can be accessed in the requestEnd event of the dataSource.

e.g.

function onRequestEnd(e) {
       var myProperty = e.response.MyProperty1;
    }
