[Farshad]

Hi there,

I have created a webpart include a RadTreeView in Sharepoint 2010. However, when I open the IE to see webpart , I see following  script error:

Message: 'RadTreeView1_NodeClicked' is undefined
Line: 1481
Char: 5
Code: 0
URI: http://kms/SitePages/Home.aspx

My Visual Webpart code(.ascx) is such as follow:

Hi,

As far as I understand - you are trying to handle the server-side NodeClick event of the RadTreeView.

However in your code you have attached the "RadTreeView1_NodeClicked" event handler to OnClientNodeClicked - which is not correct. That is the reason why you receive an error.

NodeClick is a server-side event and OnClientNodeClicked is a client-side event.
