Custom Attributes on a RadTreeNode checkbox

[Dave]

I've been searching around and I can't find anything pointing me in the right direction to do this. I need to add a custom attribute to each checkbox associated with a RadTreeNode inside of a RadTreeView. Not every node is checkable, but for the ones that are I need to figure out a way to add a custom attribute to those checkboxes. Does anyone have any suggestions?

Let me know if you need more info to help me out.

Hello Dave,

Try the following client side code in pageLoad.

Javascript:

<script type="text/javascript">
    function pageLoad()
    {
        var treeview = $find("<%= RadTreeView1.ClientID %>");
        var i;
        for (i = 0; i < treeview.get_allNodes().length; i++)
       {
            var currentNode = treeview.get_allNodes()[i];
            var checkBoxElement = currentNode.get_checkBoxElement();//accessing the checkbox
            checkBoxElement.setAttribute("NewAttribute", " AttributeValue");//adding custom attribute.
            alert(checkBoxElement.getAttribute("NewAttribute"));
       }
    }
</script>

Thanks,
Princy.

Hello Princy,

That should be the way!
I would only correct it to cache what's gathered by get_allNodes function, something like the following:

function pageLoad()
{
    var treeview = $find("<%= RadTreeView1.ClientID %>");
    var allNodes = treeview.get_allNodes();
    for (var i = 0; i < allNodes.length; i++)
   {
        var currentNode = allNodes[i];
        var checkBoxElement = currentNode.get_checkBoxElement();//accessing the checkbox
        checkBoxElement.setAttribute("NewAttribute", " AttributeValue");//adding custom attribute.
        alert(checkBoxElement.getAttribute("NewAttribute"));
   }
}

Thanks a ton! That worked perfectly.

I was trying to do all of that from the code-behind initially and just kept hitting into walls.
