How to Pass Additional Data With the DataSourceResult Back to the View


Product Telerik UI for ASP.NET MVC


How can I pass additional data with the DataSourceResult from the Controller back to the View?


The desired result can be achieved by following the steps below:

  • Store the output of the ToDataSourceResult method call in a variable.
  • Return a custom Json result with the same field names and add the additional fields
  • Add a RequestEnd event handler to retrieve the additional data in the View
var resultFinal = result.ToDataSourceResult(request);
return Json(new
       Data = resultFinal.Data,
       Total = resultFinal.Total,
       AggregateResults = resultFinal.AggregateResults,
       Errors = resultFinal.Errors,
       myAdditionalParam= "additional data", // Add the extra value
 .DataSource(dataSource => dataSource
    function requestEnd(e){
        //access the additional data sent from the Controller
