Pretty simple grid that loads after you select a date range.

$(document).ready(function () {
                var start = $("#start").kendoDatePicker();
                var end = $("#end").kendoDatePicker();
                $("#load").click(function () {
                    orderDataSource.read();
                });
                var orderDataSource = new kendo.data.DataSource({
                    pageSize: 10,
                    transport: {
                        read: {
                            url: MyOrdersUrl,
                            contentType: "application/json; charset=utf-8",
                            dataType: "json",
                            data: {
                                start: function () { return $("#start").val(); },
                                end: function () { return $("#end").val(); }
                            }
                        }
                    },
                    schema: {
                        data: "d",
                        model: {
                            fields: {
                                Id: { type: "number" },
                                d_OrderDate: { type: "date", parse: parseJSONDate },
                                d_DueDate: { type: "date", parse: parseJSONDate },
                                Phone: { type: "text" },
                                Type: { type: "text" }
                            }
                        }
                    },
                });
                var grid = $("#grid").kendoGrid({
                    dataSource: orderDataSource,
                    autoBind: true,
                    filterable: true,
                    columnMenu: true,
                    sortable: true,
                    pageable: true,
                    columns: [
                    { field: "Id" },
                    { field: "d_OrderDate", title: "Order Date", format: "{0:MM/dd/yyyy}" },
                    { field: "d_DueDate", title: "Due Date", format: "{0:MM/dd/yyyy}" },
                    { field: "Type" },
                    { command: { text: "View Details", click: showOrder }, title: " ", width: "140px" }                    
    ]
 }).data("kendoGrid");
});

When you select your dates and select load the grid it populates perfectly but it is not paged and the pager arrows are inactive. If I select the drop down and change the "items per page" then the grid properly filters and pages and becomes active. Is there a way to trigger the grid to page the items after they load?

Hello Rich,

Looking at the provided code snippet I suspect that the behavior you have described is caused by the fact that the total number of records is not return with the server response. This is required if paging is enabled and remote binding is used. Note that you should also specify the response field which holds the total number of records within the schema declaration.

Hello Rich,

Rosen is correct!!!

here is the code you can put

just change the schema like this

  schema: {
                        data: "d",
                        total: function(result) {
                             return result.d.length;
                        },
                        model: {
                            fields: {
                                Id: { type: "number" },
                                d_OrderDate: { type: "date", parse: parseJSONDate },
                                d_DueDate: { type: "date", parse: parseJSONDate },
                                Phone: { type: "text" },
                                Type: { type: "text" }
                            }
                        }
                    }


Hope this will work for you
