Ok, that worked, but now I have another very related issue. The line of code below is in my NodeClicked method and in the debugger it displays the key correctly. But where do I get the "5" (or whatever node number) from? I thought it was INDEX, but that does not return anything.
This.Treeview.Nodes(5).Key
>Key ID is same as object name - same rules
>First letter must be alfa or _.

>You can use "X"+LTRIM(STR(n,11)) OR "X"+STRTRAN(STR(n,11)," ","0")
