Endless Scrolling in Kendo Grid

What is Endless Scrolling?

Normally grid uses pagination.

But endless scrolling automatically loads more data while scrolling.

This improves user experience.

Example

scrollable: {
    endless: true
}

Full Example with Endless Scrolling

$("#grid").kendoGrid({

    dataSource: {
        transport: {
            read: {
                url: "/Home/GetStudents",
                dataType: "json"
            }
        },

        pageSize: 50,

        serverPaging: true
    },

    height: 500,

    scrollable: {
        endless: true
    },

    sortable: true,

    filterable: true,

    columns: [
        { field: "StudentId", title: "ID" },
        { field: "StudentName", title: "Name" },
        { field: "City", title: "City" }
    ]
});

What Does pageSize: 50 Mean?

pageSize: 50

👉 Grid fetches 50 records at one time.

When user scrolls:

Next 50 records load automatically
Then next 50 records load

This improves:

✔ Performance

✔ Speed

✔ Memory usage

Server Side Data Fetch Example

Controller

public JsonResult GetStudents(int page, int pageSize)
{
    List<Student> list = new List<Student>();

    for (int i = 1; i <= 500; i++)
    {
        list.Add(new Student
        {
            StudentId = i,
            StudentName = "Student " + i,
            City = "Ahmedabad"
        });
    }

    var data = list.Skip((page - 1) * pageSize).Take(pageSize);

    return Json(data, JsonRequestBehavior.AllowGet);
}

Explanation

Skip((page - 1) * pageSize)

👉 Skips previous records

Take(pageSize)

👉 Fetches only 50 records

Why Use 50-50 Data Fetching?

If database has:

100000 records

Loading all data together makes application slow.

Using:

pageSize: 50

Only 50 records load at a time.

Advantages of Endless Scrolling

✔ Faster loading

✔ Better performance

✔ Smooth user experience

✔ Less memory usage
