Retrieve Only the Visible Grid Columns Data with the $select oData Parameter

Environment

Product Progress Kendo UI Grid

Description

How can I retrieve the columns data that is visible only from the remote service by using the $select oData parameter?

Solution

  1. Pass additional parameters to the oData service by using the transport.read.data option.
  2. Query the oData service to retrieve only the visible columns data.
<div id="example">
    <div id="grid"></div>
</div>

<script>
    $(document).ready(function() {
        $("#grid").kendoGrid({
            dataSource: {
                type: "odata",
                transport: {
                    read: {
                        url: "https://demos.telerik.com/kendo-ui/service/Northwind.svc/Orders",
                        data: {
                        $select: getColumns
                        }
                    }
                },
                schema: {

                        fields: {
                            OrderID: { type: "number" },

        function getColumns() {
            return $("#grid").data("kendoGrid")
                .columns
                .filter(item => !item.hidden)
                .map(function(item) {
                    return item.field
                }).join(",");
