I am trying to call javascript function LoadItem when the contextmenu Item will be clicked. here is my codebehind file.

protected void RadTreeView1_NodeClick(object sender, RadTreeNodeEventArgs e)
        {
            this.NodeText = e.Node.Value;

        }

protected void RadTreeView1_ContextMenuItemClick(object sender, RadTreeViewContextMenuEventArgs e)
        {
            if (e.MenuItem.Text == "Add New Page")
            {
                //radpanel1.Visible = true;
                //txtTile.Text = this.NodeText;
                e.MenuItem.NavigateUrl = "http://www.google.com";
                e.MenuItem.Target = "contentview";
            }
            else if (e.MenuItem.Text == "Remove")
            {
                RadTreeView1.SelectedNode.Remove();
            }
        }

Hi,
I have solved the issue. just called javascript function in the following way:
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "tt", "LoadItem('test','http://www.google.com');", true);
it works.
Thanks.
