In codebehind of my asp.net page has a button and when single-click her open a RadWindow, don't have a problem.
The problem is when somebody close the radwindows, because to open is necessary double-click. I don't like this.
For me control refresh to disable the double-click page I use:
 Boolean IsPageRefresh;
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            ViewState["postids"] = System.Guid.NewGuid().ToString();
            Session["postid"] = ViewState["postids"].ToString();
        }
        else
        {
            if (ViewState["postids"].ToString() != Session["postid"].ToString())
            {
                IsPageRefresh = true;
            }
            Session["postid"] = System.Guid.NewGuid().ToString();
            ViewState["postids"] = Session["postid"].ToString();
        }
    }
But don't work, somebody use F5 or click in button the radwindow open again.
How can I detect to difference when use F5 and Click button?
