ComboBox Performs Repetitive Requests While Filtering in ASP.NET
Environment
| Product | Progress® Kendo UI® ComboBox for jQuery |
| 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
};
}
