ComboBox Performs Repetitive Requests While Filtering in ASP.NET

Environment

Product Progress® Kendo UI® for jQuery ComboBox
Operating System Windows 10 64bit

Description

Repetitive requests in the jQuery ComboBox are performed while filtering in ASP.NET.

Cause

Repetitive requests that are performed by the Kendo UI ComboBox component are caused by the response from the ASP.NET Web API Order controller.

Solution

The total configuration has to respond to the total number of records that are found after filtering, that is, dataResult.Count. Otherwise, the component continues to request the remainder of the total.

The following example demonstrates how to change the service accordingly.

   public object Get(int? take = null, int? skip = null, string q = null)
    {
        List<OrderModel> dataResult = string.IsNullOrEmpty(q) ? Orders.Skip(skip ?? 0).Take(take ?? int.MaxValue).ToList() : Orders.Where(m => m.Name.Contains(q)).ToList();
        return new
        {
            total = dataResult.Count,
            data = dataResult
        };
    }
