    Hi

    I would like to detect a key down when i press a node expand in my tree view. In this way I can decide to expand all nodes on a tree if for example the Shift key is hold down why pressing the expand.

    Hi Jeppe,

    Checkout the following client side code which shows how to check whether Shift key is pressed when expanding the node using keyboard.

    javascript:
     
    <script type="text/javascript"> 
    function OnClientNodeExpanding(sender, args) 
    { 
        alert('KeyCode is :'+args.get_domEvent().keyCode); 
        if(args.get_domEvent().shiftKey) 
        { 
            alert("shiftKey is pressed"); 
        } 
    } 
    </script> 

    -Shinu.

    Thanks for the answer.

    I am not sure how I can use that server side to call a ExpandAllNodes function?

    Anyway I solved it by adding a context menu item to the nodes instead. So to expand only current node press the the +, else right click and expand all.
