Hey,

I need to be able to disable a parent node but still allow the expand functionality on that node.  Can anyone explain how I can do that.  Right now the expand doesn't work when I disable the node.

Thank you,


Steve.

When you disable it you could then add an on node clicked event handler on the click side to expand and collapse the node.  Check out this page for more information.

That's a great idea accept that the +/- still doesn't work and it's not very intuitive to the user.  I don't want to make our system less user friendly just because of limitations in the controls and I would prefer to not custom code it because that just make it more difficult to upgrade.

Perhaps just changing the css class to make it look disabled?  Another way would be to put two treeviews on the page, one on top of the other.  It's probably not the best idea, but it would work.
