Hi,
I need an urgent help in tree-view control. I am not able to attach the sample project which has the problem i am facing.
when i am binding a boolean property to checkstate using code behind and converter as suggested the parent node is behaving in a crazy manner.
If i check 2 out of 3 children under a parent node then parent node is showing state of checkbox as intermediate. But if i check the 3rd child also the state of parent node remains intermediate which should get changed to on(checked) or if i uncheck one of the child node then the parent node state changes to off(unchecked) which should remain in intermediate.
I think there is some bug in the control. but if there is some trick which can fix this will help me a lot. I tried to create a support ticket also but its showing some server error.
Thanks for any help.
thanks,
Anil

Hello Anil,
Thank you for contacting us.
We suppose the problem is due to a binding to a boolean property. Please try to bind to a nullable-boolean one.
Attached you can find both a Silverlight and a WPF examples.
We hope this will help you.
Kind regards,
Ivan
