This solution doesn't work for me I mean after applying this solution the checkbox looks like disabled but functioning same as before .
Please note: I don't want to hide the checkbox i want to disable so that user can't change the selection.
Thank You in advance.

Hello,
The approach implemented in the E2011 example has no effect starting with v.11.1, since the Three-state checkbox feature was introduced. We created a report about this limitation T327780: ASPxTreeList - It is impossible to disable a selection check box and currently, it's possible to achieve this task using the undocumented API.
I've attached a sample demonstrating the approach suggested in the T326091: How to disable selection checkboxes in the ASPxTreeList thread.
Hello,
It seems that the issue may occur because the collection of nodes to be disabled contains invisible nodes. I've modified the client-side code, so that it also checks whether a node to be disable is visible on a page. Please review the attached sample and let me know if the issue persists.
