Hi all,

I'm trying to get the count of checked nodes within the client to enable a submit button if count > 0.
I know to loop all the nodes of my TreeView Nodes Collection, but I'm afraid I don't know on how to address the root node collection of my TreeView element (called channelView).

Could anyone please point me in the right direction please?

kind regards,
/matthi.

Is the simple channelView.Nodes client-side reference not applicable in your case?

I tried an alert(channelView.Nodes.Length) and got "undefined" - which, honestly, worries me...

Besides, I do on demand loading of the nodes (not the root node itself) for performance reasons...

You should try to use lower case for Length property:

channelView.Nodes.length

What do you get in this case?

Thanks. This helped (at least for now).

Yeez... One should never program whilst having a bad flu.

Thanks a million!
