Is it possible to load usercontrol in RadMenu OnClientItemClicked?

[Arun]

protected void RadMenu1_ItemClick(object sender, Telerik.Web.UI.RadMenuEventArgs e)
    {
        if (e.Item.AccessKey.ToString() == "1")
        {
            Control control = LoadControl("home.ascx");
            control.ID = control.ToString();
            ContentPlaceHolder1.Controls.Clear();
            ContentPlaceHolder1.Controls.Add(control);
        }
        else
        {
            Control control = LoadControl("abt.ascx");
            control.ID = control.ToString();
            ContentPlaceHolder1.Controls.Clear();
            ContentPlaceHolder1.Controls.Add(control);
        }
    }

The above code works fine. And the refresh is eliminated using RadAjaxManager, but for further development process we need do do the above function in client side. I dnt hve an idea whether its is possible, or is there any better method that can be followed to do this in client side.

Thanks in Advance.
