    Hi,

    Thank you for the code snippets.

    The loading of a local JSON data file in the Kendo UI DataSource component could be implemented as follows:

    1. Format the JSON data as JSON Array (array of JSON objects)
    var localData = [
{
  "property1": "test value",
  "property2": test value 2
}, { ... } ];

        2. Include the file on the HTML page:

    <script type="text/javascript" src="fileName.json"></script>

        3. Update the "transport'' configuration of the data source by specifying the "url" to point to the location of the data (the JSON Array):

    dataSource: {
  transport:{
      url: localData,
      type: "json",
      read:  function (e) {
        e.success(localData);
      }
  },
  ...
}

    Would you please give a try of this example and let me know if it works properly at your end?

    Feel free to let me know if you need any further assistance.
