I have a treeview set with multi-Node selection.

When I make a single selection (click a node with no key pressed) I have a postback and it's OK.
When a hold a shift key and click a row to have multiple selections, I do not get a postback? Is there a way to get a postback in this situation?

Hi Stanley Speer,

Thank you for contacting Telerik Support!

I think this is a normal behavior - when you have the Shift key pressed and MultiSelect is enabled, then PostBack is not fired because the tree expects you to select another node.
Can you tell me what do you want to achieve?


All the best,

Hi,

I also have a problem with this.  What I want to do is dynamically output the list of selected nodes as they are muli-selected but as there does not seem to be any postback during this process I'm not sure how to accomplish it.

Any ideas?

Hello Neil,

You can accomplish this client-side - subscribe to the OnClientNodeClicking event and update the label with the node's text:

function OnClientNodeClickingHandler(sender, eventArgs) 
    var text = eventArgs.get_node().get_text(); 
    var label = document.getElementById("Label1"); 
    label.innerHTML += text + "<br>"

I hope this will get you started.




Best wishes,
