Problem adding child nodes in treeview
I am getting an exception thrown when trying to add a child node to a treeview. The data for the Parent node is held in an arraylist, the data for the Child nodes is held in an arraylist that is part of the parent array.
The exception is at ....salesorderIDArray.Inde
and is 'Specified argument was out of the range of valid values.
Parameter name: index'
The Parent node is shown correctly.

Thanks for your fresh pair of eyes, I had got 'code blind' and totally missed the error. Perhaps a change in variable names would have helped me here in distinguishing what was the TreeView and the 'New Nodes To Add'.
The below code works.
The below code works.
' Add a root TreeNode for each object in the ArrayList.
