DataManager doesn't send take and skip in my DropDownList control

[Fercap]

Hello, 

var customerList = ej.DataManager({ url: "Administration/GetGroups", crossDomain: true }); $(function () { obj = $('#groupCodeList').ejDropDownList({ dataSource: customerList, fields: { text: "ContactName", value: 'ContactName' }, itemsCount: 20, popupHeight: "200px", width: "250px", enableFilterSearch: true, enableServerFiltering: true, allowVirtualScrolling: true, search: function (args) { if (args.searchString.length < 3) { //check search string length args.cancel = true; } } }).data("ejDropDownList"); obj._updateSelectedIndexByValue = function () { } });

And my C# controller: public IActionResult GetGroups(ExtendedDataManagerRequest dm) { return null; }

In the console browser call I see: 

Why don't I have the take and skip?

I also took the opportunity to ask, how do I add the extra parameter that I want to send in javascript?

Hi Fernando,

Greetings from Syncfusion support.

Query 1 : Why don't I have the take and skip?

For the above requirement we suggest you to set Take (top) parameter to the filter query , which will get the required number of items from the server .For more details , kindly refer to the below documentation.

Query 2: how do I add the extra parameter that I want to send in javascript?

Yes we can send additional parameter to the server as like below code , Also refer to the attached documentation below for more details about it.

const SERVICE_URI =  'http://services.odata.org/V4/Northwind/Northwind.svc/Orders';

 

var table = (document.getElementById('datatable'));

 

new ej.data.DataManager({ url: SERVICE_URI, adaptor: new ej.data.ODataV4Adaptor })

    .executeQuery(new ej.data.Query().addParams('$top', '7'))

    .then((e) => {

        (e.result).forEach((data) => {

            table.appendChild(compiledFunction(data)[0]);

        });

    });
