Is
there any way to display �busy� or �loading� or �please wait� status � while a
large number of children are dynamically loaded � either with status text or
cursor busy graphic? � and disable IE�s slow script warning?
Tree has two events (pro version) - XMLoadStart and
XMLLoadEnd - those events called on any action related to tree XML loading
parsing.
You can use them to organize any kind of “busy” message (See
in documentation samples/pro_xml_loading.html)
