Treeview isDisabled should allow fully controlling disabled states of each item

[isDisabled]="disabled || isDisabled(node, nodeIndex(index))"

Because of the hardcoded disabled property, isDisabled cannot be reliably used to control which item is disabled.

Disabling the parent node automatically disables the entire tree under it and isDisabled is never called for those items.

It should behave like other functions - isChecked, isExpanded, isVisible etc - where you have full control over which item does what.

Hi Bryan,

This feature is added specifically to Kendo UI for Angular component library. For questions related to Kendo UI for jQuery, please open a technical support ticket for the jQuery product line as they can answer your question more precisely.

Is this only being added to Angular or is there work to add this to the Jquery version as well?

Hi Mauro,

Thank you for the provided feedback.

I am happy to say that the team is going to extend the functionality and provide more options to the developers. The improvements are as follows:

1. The ability to disable parent nodes only.

2. The ability to expand a disabled node.

3. Option to hide checkbox for disabled nodes.

4. Update disabled checkbox state.

I will update the status of the feature request and the release of the improvements is expected in R2(17th March) or late R3(Mid-September).
