Load on demand, tri-state and getting the checked nodes
posted

I created a tree with load on demand enabled with tri-state checkboxes. This is working perfectly.
However, when I do a postback, I want to be able to access the child nodes of the parent which I checked (without expanding the parent first!).

For example:

My tree looks like this (with "Parent 1" not expanded)

  • Parent 1
  •  
    • Child 1
  •  
    • Child 2
  •  
    • Child 3

Then when I check the tri-state checbox @ "Parent 1" and do a postback, the selectedNodes property doesn't contain the child nodes (since they are not loaded).

How can I access those nodes without expanding "Parent 1" first?
