asp.net - .net using and reaching public value -

i wrote code in .net. when want change ‘s’ clicking button2, doesn’t change. mean after clicking button2 , click button1 see changes nothing changes. how can change , access value of ‘s’ properly. doing wrong?

public string s;  public void button1_click(object sender, eventargs e) {     label1.text = s; }  public void button2_click(object sender, eventargs e) {     s = textbox1.text;   } 

you need understand how web applications work.

in each post instance of class handles page loaded, when click on button 1, page post , loads again, way variable s isn't loaded content.

to make code work, need save s values on page viewstate.

try replacing "public string s;" this:

public string s {     {  return (string)viewstate["myvalue"]; }     set [ viewstate["myvalue"] = value };  }
