Using DropDownList elements that use virtualized data sources, is it possible to set (or reset) the values programatically?
Basically I'm looking for some guidance on how to make cascaded virtualized drop down lists where I can set the values from some external event such as the click of a button.
Things I've tried so far:
1. Simply setting the value using $('#identifier').data('kendoDropDownList').value('some value'); <== Can't set the value since it doesn't exist in the data() elements
2. Calling the read method of each drop down first via $('#identifier').data('kendoDropDownList').dataSource.read(), then setting the value (timing issue?) <== same issue as 1 since the read hasn't finished yet.
3. Hacking the jqXHR object which appears to hang off the dataSource.read() method (again timing issue?)
$('#identifier').data('kendoDropDownList').dataSource.read().done = someOtherFunction <== where 'someOtherFunction' actually does the .value() setting, this does actually run the method, but again... timing
4. Adding the necessary element to the data via the .add method, setting the value, then doing the read <== this "appears" to work but the value isn't actually selected after the read returns. Clicking on the dropdown has the placeholder element selected rather than the value
