How can i remove the postback when i click in a node of the RadTree??

As far as i know, PostBack happens when i handle the event 'onnodeclick', but i need to use this method to catch the value of the clicked node.

Not use "__doPostBack()"

How can i acomplish that?

$create(Telerik.Web.UI.RadTreeView, {"_postBackDEFANGED_OnClick":true,"_postBackOnContextMenuItemClick":true,"_postBackReference":"__doPostBack(\u0027ctl00$filas$dckFilas$C$tevFilasPublicas\u0027,\u0027arguments\u0027)","_scrollPosition":0,"_skin":"Default","_uniqueId":"ctl00$filas$dckFilas$C$tevFilasPublicas","clientStateFieldID":"ctl00_filas_dckFilas_C_tevFilasPublicas_ClientState","collapseAnimation":"{\"type\":12,\"duration\":100}","contextMenuIDs":["MainContextMenu"],"expandAnimation":"{\"duration\":100}","nodeData":[{"value":"1"},{"value":"2"},{"value":"3"},{"value":"4"},{"value":"5"},{"value":"6"},{"value":"7","selected":1},{"value":"8"},{"value":"9"},{"value":"10"}],"selectedIndexes":["6"]}, null, null, $get("ctl00_filas_dckFilas_C_tevFilasPublicas"));

Hi fabio,

You can suspend the node click event and postback after a confirmation, as shown in this kb article:

Using radprompt and radconfirm with Telerik navigational controls 

Is this what you need?

Hello fabio,

You can either set the PostBack property of the node in code-behind, or cancel the OnClientNodeClicking client-side event using the set_cancel() method.
