Hi Try like this in your firstpage.aspx create one Application Variable for maintaining the list of clicked button protected void Button1_Click(object sender EventArgs e) { AddVistedButton(BUTTON1); } private void AddVistedButton(string btnId) { string data = string.Empty; if (Application[VisitedButton] != null) { data = Application[VisitedButton].ToString(); } data =data+  + btnId; Application[VisitedButton] = data; } private void HideButton() { if (Application[VisitedButton] != null) { string data = Application[VisitedButton].ToString(); string[] arrayData = data.Split(.ToCharArray()); foreach (var s in arrayData) { switch (s) { case BUTTON1 : BUTTON1.Visible = false; break; case BUTTON2: BUTTON2.Visible = false; break; case BUTTON3: BUTTON3.Visible = false; break; //so on } } } } call HideButton() from page_load Regards Iftikar

BUTTON1	BUTTON2	BUTTON9
BUTTON4	BUTTON5	BUTTON6
BUTTON7	BUTTON8	BUTTON9
