Treeview pre-loading control

[Eilsa@Office]

I am using the Treeview control and I feel that the "load on demand" is not
useful. In my program, I have 4 level nodes in the treeview. I coded the
"ExpandLevel=1" and AutoPostBack ="True".

When I click on the Level 1node, it will retrieve the Level 2 nodes from the
database and so on. However, can i PRE-LOAD the Level 2, level 3 and level 4
even the "ExpandLevel=1" and AutoPostBack = "False"????

Thanks

Best Regards,
Aslie
