Customising a webcontrol

[majid]

I'd like create a new treeview control derived from
the TreeView and add some additional methodes to it.
How can i do it?

There are 2 files that are used. One's the compiled C# code. The other is
the .htc that is used by IE (5.5 and later) to do the rendering logic. So
it depends on what you want to do. You can subclass the C# code, but I
think with the .htc you just copy the file, rename it, and use it as a
starting point for your own efforts. Then, of course, you need to install
the .dll and the .htc files in your server's directories. I've managed to
make some pretty useful modest changes to the TreeView -- e.g., clicking a
node doesn't expand/collapse the node unless the node was already
selected...

Hope that helps,
