problem with Form/SpliContainer/TreeView/AddOwnedForm ..

[Didier Bolf]

hello

I use the framework2.0

When you have a Form which contains a usercontroll which contains a
splitcontainer
which contains a TreeView in the left panel of the splitcontainer. Then when
the text
of a treenode is too long for the width of the left panel of the
splitcontainer, a tooltip
will appear with the text of the treenode when the mouse is hover this
treenode.
my problem :

in the code I got, I have a Form which contains a usercontrol which contains
a
splitcontainer which contains a TreeView in the left panel of the
splitcontainer.

But on the Form there is a handler for the Load event and in the Load event,
the usercontrol is removed from the form and added in a new Form and then
AddOwnedForm is used...
it works fined but the tooltip does not appear anymore when the mouse is
hover
a treenode :(

the code :

private void MainForm_Load(object sender, EventArgs e)
{
SuspendLayout();
OwnedForm f = new OwnedForm();
ArrayList l = new ArrayList();
foreach (Control c in Controls)
l.Add(c);
Controls.Clear();
f.SuspendLayout();
foreach (Control c in l)
f.Controls.Add(c);
f.ResumeLayout();
AddOwnedForm(f);
f.Show();
ResumeLayout();
}

what's wrong
thanks a log for your help
