Add this in your class:

#region Browser Refresh
private bool refreshState;
private bool isRefresh;

protected override void LoadViewState(object savedState)
{
    object[] AllStates = (object[])savedState;
    base.LoadViewState(AllStates[0]);
    refreshState = bool.Parse(AllStates[1].ToString());
    if (Session["ISREFRESH"] != null && Session["ISREFRESH"] != "")
        isRefresh = (refreshState == (bool)Session["ISREFRESH"]);
}

protected override object SaveViewState()
{
    Session["ISREFRESH"] = refreshState;
    object[] AllStates = new object[3];
    AllStates[0] = base.SaveViewState();
    AllStates[1] = !(refreshState);
    return AllStates;
}

#endregion 

And in your button click do this:

protected void Button1_Click(object sender, EventArgs e)
{
    if (isRefresh == false)
    {
        Insert Code here
