Create One Method and Call at refresh button.

like that....

public void ClearAll(form frm)
{
     foreach(Control ctl in frm.Controls)
     {
        if(ctl is Textbox)
          {
             ctl.text="";
          }
        if(ctl is checkBox)
          {
            ctl.selectedIndex=0;
          }
     }
}

hi sanjeev,

you can find when refresh browser like this

C#

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            Session["CheckRefresh"] = Server.UrlDecode(System.DateTime.Now.ToString());
        }
if (Session["CheckRefresh"].ToString() == ViewState["CheckRefresh"].ToString())
        {
            Label1.Text = "Hello";
            Session["CheckRefresh"] = Server.UrlDecode(System.DateTime.Now.ToString());
        }
        else
        {
            Label1.Text = "Page Refreshed";
            string str = "your code will save here or call save() method here";
//and here you can call clearallfields() method
        }


    }

C#

protected void Page_PreRender(object sender, EventArgs e)
    {
        ViewState["CheckRefresh"] = Session["CheckRefresh"];
    }
