Select Multiple Nodes --> Select/Click events in server Side

[July]

I have a RastreeView... such as:


Every node has an attribute
Folders has attribute["Type"] = "F"
and documents has attribute["Type"] = "D"

When create a TV for every node assign ContextMenu
Document has --> document Context Menu
Folder has --> Folder Context Menu

I NEED change contextMenu if user do:
-- click on Documents and Folders --> Change to COMMON MENU

I do this in RastreeView ClickNode event , but does not work if I selected every node with Control+click or shift+click

Where I can catch all selected nodes and change on runtime ContextMenu??

Hi Julieta,

In the NodeClick event of RadTreeView the selected nodes are already changed so you need an event that will fire until the nodes are still selected. One possible way is to add new context menu item and change the context menu in  OnContextMenuItemClick.

Hope this will be helpful.

Hi Julieta,

 
You can get the selected nodes in the onClientNodeClicking event as in the code bellow and send it to server through AjaxRequest:

function OnClientNodeClicking(sender, args) {

                sender.trackChanges;
                for (var index in sender.get_selectedNodes()) {

                alert(   sender.get_selectedNodes()[index].get_text());
                }
                sender.commitChanges;

            }

Hope this will help.
