When I select a node in a TreeView, I'd like the ability to unselect it without selecting a different node by clicking the node (to toggle it selected or unselected)

<telerik:RadTreeView ID="blocks"  ShowLineImages="false" runat="server" OnClientNodeClicked="BlockClicked" MultipleSelect="true">
    <NodeTemplate >
......
    </NodeTemplate>
</telerik:RadTreeView>

This JavaScript doesn't seem to do what I thought...

function BlockClicked() {
        var tree = $find("<%= blocks.ClientID %>");
        var node = tree.get_selectedNode();
        if (node.IsSelected == false) {
            alert('Selected');
            node.unselect();
        }
        else {
            alert('Not Selected');
            node.select();
        }
    }

Hello,


You could enable the default checkboxes of RadTreeView and try teh following client code to accomplish your requirement.

Code:

Any way to  do this without using the checkboxes?

Seems the "OnClientNodeClicking" event did the trick:
