Customize treeview control nodes ???

[serge calderara]

Dear all,

I was wondering is there is a way to customise the treView control in order
to get any Control as a Node. What I try to do is having a Progress bar as a
treeview node object.

Is that possible ?

I know you can attach right-click popup menus and manage the events
results of those.

You cant add controls directly to a node. You can owner draw the node however
and either draw your own progress bar on it, or have a hidden progress bar
and try to convince it to draw itself onto an image. There should be at least
a win32 call to create a device context for the image and tell the control to
draw on it. I know there are samples like that about for taking screen dumps
so you could probably modify those.

He might want to consider just having a form that responds to the
selection of the node...that is what my smart client does...as the user
selects a node in the tree, it calls a web service and updates fields on
the main form. He should be able to do this, or launch a small
subform with a mouseover or click.

The thing I am looking for to do is as follow:
I have a treeview object whcih has different nodes.
When my user select each of this nodes, a particular long operation can be
done on each of them asynchronously. For that reason I would like that when
operation is goiing on on that selected node (ex: getting data from
database), the default node bitmap is replaced by a progress bar to have
independant process status of each node..

In a similar way when you are using an FTP programme and upload a certain
amount of files, then you have progress of each file.. This is what I try to
reached with tree nodes.

thnaks for help if any idea?

I think you'll probably have to look at a custom tree control to do
this. There are a number of commercial products that allow you to
embed controls in tree nodes. Most only support inserting custom
editor controls from the same vendor. Infralution's Virtual Tree
control supports using any .NET control (including progress bars) as an
editor. You can can get more information and download an evaluation
version from:
