TreeView Double Click Event Strange Problem

[Navid]

Hello,
I have a tree view which has Check Box's beside each node.
In the BeforeCheck event Handler I have canceled the event to
prevent the user from Checking/ Un-checking the box:
private void treeView3_BeforeCheck(object sender, TreeViewCancelEventArgs e)
{
e.Cancel = true;
}
I am trying to now set up the DoubleClick event but the first time
the user double clicks the event is not called. For example the first
time clicked it will expand/Collapse the node but the event will not be
called. Every time after that it works correctly.
All I am doing currently is doing a Console.WriteLine();
private void treeView3_DoubleClick(object sender, EventArgs e)
{
Console.WriteLine("Double Click Invoked");
}
A co-worker also has a similar problem with right clicking to bring up
a context menu. The first time it does not work then every time after
that it works as expected.

The following is under the InitializeComponent();

this.treeView3.DoubleClick += new
System.EventHandler(this.treeView3_DoubleClick);

this.treeView3.BeforeCheck += new
System.Windows.Forms.TreeViewCancelEventHandler(th is.treeView3_BeforeCheck);

This Problem occurs every time the tree view is repopulated, Which is
simply done by clicking a button.

Any ideas would is appreciated.
