Fixed bug in IE Treeview Webcontrol when clicking on leaf node.

When I clicked on a leaf node in the treeview control I would sometimes get
an error message "tabName is null or not an object". The error was being
produced by the client side script at line 209 (version 1.0).

if (textnode.tagName.toLowerCase() == "treenode")

It turns out that the object textnode was null in these instances. To fix
this I added a test for null.

function HoverNode(textnode)
var node;
//Bug - Jan 1 2005 WRM Clicking on leaf would result in error "tagName is
null or not an object".
// Added test for textnode != null
if (textnode != null)
if (textnode.tagName.toLowerCase() == "treenode")
node = textnode.subtree.all.item("_tntext", 0);
node = textnode;

The file is found in the C:\Inetpub\wwwroot\webctrl_client\1_0

Hopefully this will help others and eventually find it's way into the next
Thanks for all you do

Virtually yours,
