In cases when we have loadOnDemand set to true and we want to populate the value of the DropDownTree initially we need a way to check if this value is part of the available options. One possible solution is adding a valueMapper function similar to the one use in virtualization scenarios.

Bug report

Unexpected change event triggering when using value() method of remote datasource DropDownTree with checkboxes and autoBind false

Reproduction of the problem

  1. Run the following Dojo
  2. Click on Load button to set the value of the Child item

Current behavior

Script runs through datasource read else, then through datasource read if and then DropDownTree's change event is fired.

NOTE: if there is no setTimeout or if the two nodes are loaded at the same time with no if else clause, then the issue is not reproducible.

Expected/desired behavior

DropDownTree's change event is not fired, when value() method is called.

Environment

  • Kendo UI version: 2019.2.619
  • Browser: [all]

Similar fixed issue: #4352
