hi I have a tree view that is generated at runtime. I can populate it, and save the state using the GetXML() method fine (to session). after reloading the page I use the loadxmlstring() method to re-assign the state. My issue is that after assigning the state, the parent nodes should have a negitive sign "-", instead they have a positive sign "+" so I have to click it three times to collpse the parent node.
I have tried using an arraylist and saving all the IDs of all the expanded nodes, then looping through the nodes after they are bound and using the node.expanded = true property to expand them. Doing it this way produces the same result, having to click the parent node three times to collapse it.
Also after re-assigning the state, the absolute child node isnt expanded. even though the parent is expanded.
