Hi Dean,
According to my knowledge, TreeView does not provide such a mothod for you
to scroll it in your own code. Scrollings are encapsuled in the TreeView
Class. I think you can set a flag in your code for the AfterSelect event to
identify whether the Select is from the user or your code. This might be a
workaround.

If anything is unclear, please feel free to reply to the post.

| This is an application that is like a telephone book. The treeview
| initially has only the letters "A" thru "Z" showing. There is a textbox
| above the treeview that allows the user to key in a lastname, firstname.
| When the first letter is keyed in, the children for that letter are loaded
| and the letter is expanded to show all the children. What I would like to
do
| is roll the child nodes up as the user types in the second character of
the
| name to show the first child node (and all others below it) also with
those
| two characters. I don't want to select that node, because selecting it
| would fire the node_AfterSelect event which would load a listview just to
| the right of the treeview. I only want to fire the load of the listview
| when there is only one name in the database that matches however many
| characters have been typed into the textbox.
| Firing the node_AfterSelect event on a partial match would result in too
| much activity going on in the listview. But, scrolling the treeview up to
| match the textbox characters would be very helpful. Any suggestions for
| just scrolling the treeview?
