Kendo UI: How to avoid server call when text entered in combobox is less than min length

Question

I am using Kendo UI ComboBox "version:2016:1.112.545" and using "http://demos.telerik.com/kendo-ui/combobox/serverfiltering" as reference. I set the min length as three characters(search string) for the ComboBox. So when I type three characters a request to web server should be done and it is working as expected. Now the problem is when I clear the whole content in the ComboBox, again a request to web server is done(with empty search string). How to avoid this call?

(Note: This issue can be reproduced in the above telerik demos URL. Use the browser's developer tools to monitor the server calls.)

Hey Try to use below given code:-

filtering: function(e) {
      var filter = e.filter;

      if (!filter.value) {
        //prevent filtering if the filter does not value
        e.preventDefault();
      }
  }
