Hi,
i want to display the number of currently selected nodes of my radTreeView (clientside).

so i have the nodeClicked event working fine.

var tree = $find("<%= radTreeView.ClientID %>");
var nodes = tree.get_selectedNodes();

i get the treeview object. i also got a object from the get_selectedNodes method.

But i cant get the Count fomr this array of nodes.

I tried .Count() .count() and get_count(), always getting an exception, stating that this object does'nt own such a method.

What may be helpfull?

thanks Mario

Hello Mario,


Use nodes.length for getting the count of the nodes.

Client code:
function getSelected() {
    var tree = $find("<%= treeview1.ClientID %>");
    var nodes = tree.get_selectedNodes();
    alert(nodes.length);
}

function nodeSelecting(sender, args) {
var nodes = sender.get_selectedNodes();
alert(nodes.length);
}

Where sender is a radtreeview,

It always returns 0, am I missing a property somewhere?

 

Thank You

Hi Daniel,

Please make sure that the time for executing this logic is appropriate and the nodeSelecting function is not called too. You can check that by temporarily transferring your script logic to a button client-side click handler.
