I have a TreeView with check boxes enabled. I am showing in it a hierarchy of objects, so I have objects and then subobjects for them (shown as child nodes in the TreeView). I would like to make it so, that when I select some of the children (but not all), the check box for the parent node is in the Indeterminate state (as known from the CheckBox control). Is this possible?
An alternative/customized TreeView control would also work if it is easy to handle.
