I have a treeview and a checked list view controls one beside another. I
want to make them work so that when I scroll down or up one of them the
other does the same.

Any help will be appreciated
 
Your going to have to use the Windows API to make the other control scroll
down. Trap the onVScroll event of the control which you want to be the
master and have it send a message to the slave control.

You need to use the User32.DLL and send a Message using the constant for
vertical scroll to the handle of the other control.

HTH
 
They are inherited from Control - Try this - I havent tried it for the tree
control but this is a working example for the checked listbox ( This works )

Thanks, but that one scroll only the label on the right. It does not scroll
the rich text box on the left.

Is it possible to make them scroll both at the same time?
 
Ok, I got it. I just have to send the message to the other controls as
well. I'll try this with the tree view and checked list view to check.

I appreciate your help.

I know, my point is that you CAN control the slave even though it didnt seem
to have that event, it did. It must have because otherwise the thing wouldnt
scroll.

However, I cant think how to trap the VScroll event of the TreeView. There
must be a way to do it though, I'll have a think or maybe someone else could
jump in.

They both behave differently. The TreeView has a scrollable peroperty which
hides the scrollbars, but it stops remote scrolling. the Listbox scrollbars
cannot be disabled.

Thats It

However, I cant think how to trap the VScroll event of the TreeView. There
must be a way to do it though, I'll have a think or maybe someone else could
jump in.

What about panel. I am actually using a panel with check boxes on it, not a
checked list view.

I am trying to find some references on my own, but MSDN does not says much.
I found somethig about scrollableClass with VScroll and HScroll properties
but don't know how to access them. I know that panel inherit from this
class, but don't know about treeview.

Hi,

I got a very simple sollution to this.

Put your controls simply into a panel Control, sets its property AutoScroll
to True.

The two controls inside the panel, say another pannel holding checkboxes and
a treeview should have their properties AutoScroll and Scrollable
respectively set to False.

Since panel inherits from ScrollableControl class, the two controls inside
will do the same. Therefore, no need for them to have their own scroll
bars.

What about panel. I am actually using a panel with check boxes on it,

not
a
checked list view.

I am trying to find some references on my own, but MSDN does not says much.
I found somethig about scrollableClass with VScroll and HScroll properties
but don't know how to access them. I know that panel inherit from this
class, but don't know about treeview.

Thats It


Yes, it does. Thank you. Do you know how can I make the scrollbars
invisible, so I can use only the buttons?

Thank you

Thanks, but that one scroll only the label on the right. It does

the rich text box on the left.

Is it possible to make them scroll both at the same time?

This does not work for me.
Put your controls simply into a panel Control, sets its property AutoScroll
to True. OK

The two controls inside the panel, say another pannel holding checkboxes and
a treeview should have their properties AutoScroll and Scrollable
respectively set to False.
Click to expand...
TreeView does not have Autoscroll and if you set scrollable to False it will
not scroll, Checked Listbox does not havve an option to take out the scroll
bars on vertical
