I want to prevent a TreeNode to be collapsed, so I do the following, in
the BeforeCollapse event:

// Verify if it is the root node
if (e.Node.Name == "0")
e.Cancel = true;

It works ok, but is there a way to not display the minus button?

Regards.

Junior.

Hi,
You can set the property "showplusminus" to false to hide ALL the plus
and minus signs,

HTH,
James.

Hi again,
A better way to test if it is the root would be

if (e.Node == ((TreeView)sender).Nodes[0])

Cheers,
James.

Actually, I just wanna take off the minus button from the first node,
not from all nodes.
But your answer has taken me to another property of the TreeView:
ShowRootLines.
I set it to false, and I got what I want.

Thanks.
