[CLOSED] When dynamically creating a TreePanel during page load, how do you hook up the "submitNodes" event?
I am creating a tree panel dynamically in the page load event of a page, then adding it to some container like a panel. However, I cannot figure out how to handle the "submitNodes" event as I get an error. The final solution will have the ability to add new nodes via drag and drop, but I need a way to be able to know when new nodes have been added. I thought the submitNodes would be a good way to do this - let me know if there is an alternative way to achieve this with the way I have it.
Here is my ASPX:
I guess if using
Any help very much appreciated!
Cheers.
