How to refresh kendo grid base on additional param

问题:

I have a customize Read function for kendo grid ....

 public virtual async Task<ActionResult> Read([DataSourceRequest] DataSourceRequest request,
        RecordStatus? recoredStatus){ // code here }

now I want refresh my grid by using record status in kendo with jquery

<script type="text/javascript">
function viewButtonClickHandler(e) {
        alert(e.Id)
        $('#Grid').data('kendoGrid').dataSource.read(e.Id);
        $('#Grid').data('kendoGrid').refresh();

}

but how I send this additional parameter ( recordStatus )in read function !? can I do this !?

So if you are using Kendo MVC UI you can use the Data property for the Read method of DataSource . So the client side method DataHandlerName will execute while you are requesting for the read action, by using-

    $('#Grid').data('kendoGrid').dataSource.read();

You can easily handle the client side script. Your Server Side code will be following for Kendo GRID,

    .DataSource(dataSource => dataSource.Ajax().ServerOperation(false).Read(r=> r.Action("ActionName","ControllerName").Type(HttpVerbs.Post).Data("DataHandlerName")))

And your client side code will be-

    <script> 
       function DataHandlerName() {
         //your code will goes here 

          var request={
                  id:1
                };
             return request ;
       }
   </script>

And Your Action Mehtod will be,

public ActionResult ActionName([DataSourceRequest] DataSourceRequest request,int id){}

If I understood correctly you just need this. And also please take a look to the link. It may can helps you.

function onSomeButtonClick(){
grid_.dataSource.read({q:"test"});

}

Using Purely java script this is how you can send params to read method

$('#grid').data('kendoGrid').dataSource.Read({id:e.Id});
$('#Grid').data('kendoGrid').refresh();

On Server Side you need this.

public ActionResult Products_Read([DataSourceRequest] DataSourceRequest request,int id){}

If you are using MVC based grid telerik forum already has example on how to do use read to send extra parameters .
