Hi,
I am using the treeview (from Q1 2010 SP1) to bind to hierarchial data items. All is working ok, but if all the child items of a parent item are checked, then the parent item gets automatically checked (even though it was checked). This is a problem for me as I need to be able to treat the parent item separately from the child items.
Is there a way that I can stop this from happening?
Thanks,
Mark

If you set the IsTriStateMode to false, it will allow the checkmarks to work independently of their parents/children. You can then manipulate the checks via code.

Setting the IsTriStateMode does not help (I believe the default is false for checkboxes). The checkboxes work independantly for the most part. The exception is when all of the child checkboxes are checked. When this happens the parent checkbox also becomes checked even though it was not set to be checked.
To be clear, I am setting the checkboxes to be checked in the code before it renders. After the code completes this task, the parent is still item.CheckedState = Automation.ToggleState.Off. So, something checks this parent before it is rendered (my code is not doing it).

Hello Mark Wells,
Unfortunately we are not aware of such issue. Moreover your scenario looks quite complicated.
Can we ask you to send us a sample project demonstrating the problem in order to examine it in more detail?
