Button click event handler fired on page refresh

Anonymous User 1888 22-Aug-2014

I have an asp.net control, which seems to fire the button click event handler on a page refresh. Why does this happen and how could I avoid it?

Hi Ankita, 
try this:

protected void Page_Load(object sender, EventArgs e)
    {
        if(!IsPostBack)
           
Session["update"] =Server.UrlEncode(System.DateTime.Now.ToString());
    }
    protected override void OnPreRender(EventArgs e)
    {
       
ViewState["update"] = Session["update"];
    }
    protected void btnProceed_Click(object sender, EventArgs e)
    {           
        if(Session["update"].ToString() ==ViewState["update"].ToString())
           
DisplayInfo();
    }
    private void DisplayInfo()
    {
        // Do what ever thing you want to do
       
Session["update"] =Server.UrlEncode(System.DateTime.Now.ToString());  
    }
