What do you actually mean by \"disabled\" do you need to set some specific style to node, or disable checkbox or what?

Typically, additional nodetype \"disabledNodeType\" with specific style/behavior setting is needed to be added. And used for \"disabled\" nodes.

But this is not a client-side way.

For client side, you cannot assign this \"disabled\" nodetype to node that is already in treeview.
Instead, you can remove node from treeview, set its nodetype to \"disabledNodeType\" and insert it in place of where it was removed from.

This does not look trivial.

You should probably refer to
http://www.9rays.net/asp.net_2/treeview/miscpages/doc/ClientObjects.aspx

use
var parent = node.getParent() to get original parent.
then
var index = node.getIndex()  to get node original index
then
node.remove() to remove node from its parent
then
node.setNodeTypeID(yourdisabledNodeTypeID) to set required nodetype
then
parent.insertNode(node, index);

Hope this is what you need.

hi,

i'm changing the nodetype on server side, but that doesn't seem to work.
i have a checkboxlist and the treeview in an updatePanel.
when i change the state of a checkbox in the checkboxlist i want to change the nodetype of a specified node in the treeview.
i have the checkboxlist on autopastback set to true and in the selectedindexchanged eventhandler i affect the new nodetype to the soecfied node in the treeview, but this doesn't work ther's no exception but the node changes from nodetype in a second postback of the onselectedindexchanged of the checkboxlist not in the first one where i affect the new value.
am i missing something ?
help please, thx

I can help you.

Create a simple web project with your treeview/nodetypes/etc. and send it to flytreeview.asp ** 9rays.net
So I can modify it locally and send it back to you.

Didn't receive anything.
It could be blocked by mail server.
You can also put your project to FTP:
ftp://download.9rays.net/9r_incoming/
