[Solved] Disabled nodes loaded from web service appear enabled

[Mick]

I'm seeing pretty strange behaviour from the RadTreeView control.  The treeview is load on demand...

                <telerik:RadTreeView ID="tvLocation" runat="server" AllowNodeEditing="False" OnClientNodeClicked="toggleTreeNodeExpansion"
                    OnClientNodeExpanding="toggleTreeNodeExpansion" DataFieldID="ID" DataFieldParentID="Parent" 
                    DataTextField="Name" DataValueField="ID" OnClientLoad="onLocationTreeClientLoad" OnClientNodeChecking="clearRtinTree"
                    Skin="Default" TabIndex="1" CheckBoxes="True" Height="100%" CheckChildNodes="true">
                    <WebServiceSettings Method="LoadLocationTreeNode" />


The toggleTreeNodeExpansion enables disabled nodes to be expanded...

function toggleTreeNodeExpansion(sender, args) {
    var node = args.get_node();
    if (!node.get_enabled()) {
        node.set_enabled(true);
        if (node.get_expanded())
            node.collapse();
        else
            node.expand();
        node.set_enabled(false);
    }
}

The nodes I'm returning nodes from the web service are disabled.  This is what I'm seeing...

The first and last nodes loaded have the rtDisabled style however the nodes inbetween do not, until you click on them, after which they do get the style and they appear as disabled.

Hello Mick,

The described functionality is quite unusual indeed but I could not replicate it at my side with the code provided. I am attaching my test page. Please review it and let me know what else have to be added to observe the issue.

Would you please elaborate what exactly are you trying to achieve when you click on the node because it is not quite clear from the explanation provided?
