TreeView AutoScroll

[Uwe]

Hi,

I'm currently writing my own UserControl, based on the TreeView control that
ships with .NET Framework 3.5. (i.e. Inherits System.Windows.Forms.TreeView).

Everything works fine, especially the Drag & Drop operation.

Just one question regarding the AutoScroll function. It appears to me that
this control has already a built in AutoScroll-function ... but it only
scrolls down and not up or even left and right.

Any idea how to influence that? I'm currently using the "SendMessage"-API to
scroll up, right and left and would also like to have control over the scroll
down functionality.

Another question as the MSDN On- and Offline-help falls short on that: What
does the ".AutoScrollOffset" property exactly mean and how can it be used?

Thanks for any help.

Uwe

Hi Christian,

Thanks for your answer (the only one so far ))

Well, any idea about the "AutoScroll" functionality and how to get control
over that?

Just to make sure we speak "the same language": "AutoScroll" means -in my
opinion- the TreeView scrolls all the nodes into view if the mouse comes
close to the bottom of the TreeView control, hence it scrolls down.

I would like to know how to make the TreeView scroll up? Currently I'm using
the SendMessage-API to do so, but as there is some kind of built-in
functionality I like to use this one instead of the SendMessage-API (or
overwrite this one in order to always use the Sendmessage-API).

Thanks for any idea that points me in the right direction...
Uwe
