How to get value from checked parent and child nodes if have using treeview with PopulateOnDemand properties

Question

Hi to all,

My problem is, i am using asp.net treeview with check boxes and to reduce the loading i am using populateondemand method, It is loading no problem but When i am selecting any Parent node check box it is showing the checked status false. Even Its child nodes checked status also showing false if checked any. So, pls. help to find a solution.

Example: Active - Parent Node Company Name - Child Node Location Name - Sub Child Node InActive - Parent Node Company Name - Child Node Location Name - Sub Child Node

In this way i have the tree structure with checkboxes.

Thanks in advance.
